sws: pass in socket reference to allow function to close it
The function service_connection() now passes in a reference to the
socket instead of by value since the sub function http_connect() might
close it and set *infdp = CURL_SOCKET_BAD. This would previously not be
detected when service_connection() returned and potentially cause a
double close of the socket.

curlx: move Curl_strerror, use in src and tests, ban strerror globally
Also:
- tests/server: replace local `sstrerror()` with `curlx_strerror()`.
- tests/server: show the error code next to the string, where missing.
- curlx: use `curl_msnprintf()` when building for src and tests.
  (units was already using it.)
- lib: drop unused includes found along the way.
- curlx_strerror(): avoid compiler warning (and another similar one):
  ```

checksrc: reduce directory-specific exceptions
By making them defaults, then fixing and/or reshuffling remaining
exceptions as necessary.

- checksrc: ban by default: `snprintf`, `vsnprintf`, `sscanf`, `strtol`.
- examples: replace `strtol` with `atoi` to avoid a checksrc exception.
- tests/libtest: replace `strtol` with `atol`.
- tests/server: replace most `strtol` with `atol`.
- tests/server: replace most `strtoul` with `atol`/`atoi`.
- tests/server: drop no longer used `util_ultous`.
- fix typo in checksrc rules: `vsnprint` -> `vsnprintf`.
- update local exceptions.

Also:
- examples: ban curl printf functions. They're discouraged in user code.
- examples: replace curl printf with system printf.
  Add `snprintf` workaround for <VS2015.
- examples/synctime: fix `-Wfloat-equal`.
- examples/synctime: exclude for non-Windows and non-UWP Windows.
- examples/synctime: build by default.

build: disable TCP_NODELAY for emscripten
In WebAssembly, using `TCP_NODELAY` fails with:
```
* Could not set TCP_NODELAY: Protocol not available
```

Add a new feature macro in `curl_setup.h` telling whether `TCP_NODELAY`
is known to be supported at runtime, when defined at compile-time.

Keep `TCP_NODELAY` guards at their current positions to ensure the
necessary headers (e.g. `netinet/tcp.h` and `netinet/in.h`) define it.

tests: make individual test sources compile cleanly
Tidy up headers and includes to ensure all individual test source
compile cleanly (but not link). To allow running clang-tidy (and
possibly other static analyzers) on them. It also improves readability
and allows to verify them locally, without the bundle logic.

clang-tidy ignores #included C files, so it's blind to bundle C files
the include these tests. The current workaround of embedding has
a couple of downsides:. meaningless filenames and line numbers,
missing issues, messing up self header paths. Thus, running it on
individual sources would be beneficial.

Also:
- de-duplicate includes.
- untangle some includes.
- formatting/indentation fixes.
- merge `getpart.h` into `first.h`.

tests: always make bundles, adapt build and tests
Make test bundles the default. Drop non-bundle build mode.
Also do all the optimizations and tidy-ups this allows, simpler builds,
less bundle exceptions, streamlined build mechanics.

Also rework the init/deinit macro magic for unit tests. The new method
allows using unique init/deinit function names, and calling them with
arguments. This is in turn makes it possible to reduce the use of global
variables.

Note this drop existing build options `-DCURL_TEST_BUNDLES=` from cmake
and `--enable-test-bundles` / `--disable-test-bundles` from autotools.

Also:
- rename test entry functions to have unique names: `test_<testname>`
  This removes the last exception that was handled in the generator.
- fix `make dist` to not miss test sources with test bundles enabled.
- sync and merge `tests/mk-bundle.pl` into `scripts/mk-unity.pl`.
- mk-unity.pl: add `--embed` option and use it when `CURL_CLANG_TIDY=ON`
  to ensure that `clang-tidy` does not miss external test C sources.
  (because `clang-tidy` ignores code that's #included.)
- tests/unit: drop no-op setup/stop functions.
- tests: reduce symbol scopes, global macros, other fixes and tidy-ups.
- tool1621: fix to run, also fix it to pass.
- sockfilt: fix Windows compiler warning in certain unity include order,

curlx: move into to curlx/
Move curlx_ functions into its own subdir.

The idea is to use the curlx_ prefix proper on these functions, and use
these same function names both in tool, lib and test suite source code.
Stop the previous special #define setup for curlx_ names.

The printf defines are now done for the library alone. Tests no longer
use the printf defines. The tool code sets its own defines. The printf
functions are not curlx, they are publicly available.

The strcase defines are not curlx_ functions and should not be used by
tool or server code.

dynbuf, warnless, base64, strparse, timeval, timediff are now proper
curlx functions.

When libcurl is built statically, the functions from the library can be
used as-is. The key is then that the functions must work as-is, without
having to be recompiled for use in tool/tests. This avoids symbol
collisions - when libcurl is built statically, we use those functions
directly when building the tool/tests. When libcurl is shared, we
build/link them separately for the tool/tests.

tests/server: give global path variable a more descriptive name
Use a more descriptive global variable name in server code, also
to avoid colliding with this name used elsewhere in libcurl.

This isn't causing an issue at this time, but makes the code prone

argument of the `curlx_win32_stat()` function.

core: stop redefining E* macros on Windows, map EACCES, related fixes
Before this patch, standard `E*` errno codes were redefined on Windows,
onto matching winsock2 `WSA*` error codes, which have different values.
This broke uses where using the `E*` value in non-socket context, or
other places expecting a POSIX `errno`, e.g. file I/O, threads, IDN or
interfacing with dependencies.

Fix it by introducing a curl-specific `SOCKE*` set of macros that map to
`WSA*` on Windows and standard POSIX codes on other platforms. Then
verify and update the code to use `SOCKE*` or `E*` macro depending on
context.

- Add `SOCKE*` macros that map to either winsock2 or POSIX error codes.
  And use them with `SOCKERRNO` or in contexts requiring
  platform-dependent socket error codes.

  This fixes `E*` uses which were supposed be POSIX values, not `WSA*`
  socket errors, on Windows:
  - lib/curl_multibyte.c
  - lib/curl_threads.c
  - lib/idn.c
  - lib/vtls/gtls.c
  - lib/vtls/rustls.c
  - src/tool_cb_wrt.c
  - src/tool_dirhie.c

- Ban `E*` codes having a `SOCKE*` mapping, via checksrc.
  Authored-by: Daniel Stenberg

- Add exceptions for `E*` codes used in file I/O, or other contexts
  requiring POSIX error codes.

Also:
- ftp: fix missing `SOCKEACCES` mapping for Windows.
- add `SOCKENOMEM` for `Curl_getaddrinfo()` via `asyn-thread.c`.
- tests/server/sockfilt: fix to set `SOCKERRNO` in local `select()`
  override on Windows.
- lib/inet_ntop: fix to return `WSAEINVAL` on Windows, where `ENOSPC` is
  used on other platforms. To simulate Windows' built-in `inet_ntop()`,
  as tested on a Win10 machine.
  Note:
  - WINE returns `STATUS_INVALID_PARAMETER` = `0xC000000D`.
  - Microsoft documentation says it returns `WSA_INVALID_PARAMETER`
    (= `ERROR_INVALID_PARAMETER`) 87:
    https://learn.microsoft.com/windows/win32/api/ws2tcpip/nf-ws2tcpip-inet_ntop#return-value
- lib/inet_ntop: drop redundant `CURL_SETERRNO(ENOSPC)`.
  `inet_ntop4()` already sets it before returning `NULL`.
- replace stray `WSAEWOULDBLOCK` with `USE_WINSOCK` macro to detect
  winsock2.
- move existing `SOCKE*` mappings from `tests/server` to
  `curl_setup_once.h`.
- add missing `EINTR`, `EINVAL` constants for WinCE.

tests/server: fix to check against winsock2 error codes on Windows
Windows's winsock2 returns socket errors via `WSAGetLastError()` and
not via `errno` like most systems out there. This was covered by
switching to the `SOCKERRNO` curl macro earlier. But, on Windows the
returned socket error codes have different values than the standard
POSIX errno values. Existing code was using the POSIX values for all
these checks. Meaning they never actually matched on Windows.

This patch defines a set of `SOCKERRNO` constants that map to the
correct socket error values for Windows and other platforms.

The reverse issue exists in core curl code, which redefines POSIX errno
values to winsock2 ones, breaking non-socket uses on Windows.

tests: reformat error messages to avoid tripping MSBuild
Change the format of error messages sent to stderr from tests and test
servers. As a workaround to avoid triggering Visual Studio's MSBuild
tool's built-in regexp matcher, and making it mark builds failed for
reasons we don't want them to hard fail.

Roughly, the pattern to avoid is the word "error" (case-insensitive)
in the same line with a colon `:`.

It affected GHA/windows MSVC CI jobs, causing flakiness:
```

build: add Windows CE / CeGCC support, with CI jobs
Make it possible to build curl for Windows CE using the CeGCC toolchain.
With both CMake and autotools, including tests and examples, also in CI.
The build configuration is the default one with Schannel enabled. No
3rd-party dependencies have been tested.

Also revive old code to make Schannel build with Windows CE, including
certificate verification.

Builds have been throughougly tested. But, I've made no functional tests
for this PR. Some parts (esp. file operations, like truncate and seek)
are stubbed out and likely broken as a result. Test servers build, but
they do not work on Windows CE. This patch substitutes `fstat()` calls
with `stat()`, which operate on filenames, not file handles. This may or
may not work and/or may not be secure.

About CeGCC: I used the latest available macOS binary build v0.59.1
r1397 from 2009, in native `mingw32ce` build mode. CeGCC is in effect
MinGW + GCC 4.4.0 + old/classic-mingw Windows headers. It targets
Windows CE v3.0 according to its `_WIN32_WCE` value. It means this PR
restores portions of old/classic-mingw support. It makes the Windows CE
codepath compatible with GCC 4.4.0. It also adds workaround for CMake,
which cannot identify and configure this toolchain out of the box.

Notes:
- CMake doesn't recognize CeGCC/mingw32ce, necessitating tricks as seen
  with Amiga and MS-DOS.
- CMake doesn't set `MINGW` for mingw32ce. Set it and `MINGW32CE`
  manually as a helper variable, in addition to `WINCE` which CMake sets
  based on `CMAKE_SYSTEM_NAME`.
- CMake fails to create an implib for `libcurl.dll`, due to not
  recognizing the platform as a Windowsy one. This patch adds the
  necessary workaround to make it work.
- headers shipping with CeGCC miss some things curl needs for Schannel
  support. Fixed by restoring and renovating code previously deleted
  old-mingw code.
- it's sometime non-trivial to figure out if a fallout is WinCE,
  mingw32ce, old-mingw, or GCC version-specific.
- WinCE is always Unicode. With exceptions: no `wmain`,
  `GetProcAddress()`.
- `_fileno()` is said to convert from `FILE *` to `void *` which is
  a Win32 file `HANDLE`. (This patch doesn't use this, but with further
  effort it probably could be.)
  https://stackoverflow.com/questions/3989545/how-do-i-get-the-file-handle-from-the-fopen-file-structure
- WinCE has no signals, current directory, stdio/CRT file handles, no
  `_get_osfhandle()`, no `errno`, no `errno.h`. Some of this stuff is
  standard C89, yet missing from this platform. Microsoft expects
  Windows CE apps to use Win32 file API and `FILE *` exclusively.
- revived CeGCC here (not tested for this PR):
  https://building.enlyze.com/posts/a-new-windows-ce-x86-compiler-in-2024/

On `UNDER_CE` vs. `_WIN32_WCE`: (This patch settled on `UNDER_CE`)

- A custom VS2008 WinCE toolchain does not set any of these.
  The compiler binaries don't contain these strings, and has no compiler
  option for targeting WinCE, hinting that a vanilla toolchain isn't
  setting any of them either.
- `UNDER_CE` is automatically defined by the CeGCC compiler.
  https://cegcc.sourceforge.net/docs/details.html
- `UNDER_CE` is similar to `_WIN32`, except it's not set automatically
  by all compilers. It's not supposed to have any value, like a version.
  (Though e.g. OpenSSL sets it to a version)
- `_WIN32_WCE` is the CE counterpart of the non-CE `_WIN32_WINNT` macro.
  That does return the targeted Windows CE version.
- `_WIN32_WCE` is not defined by compilers, and relies on a header
  setting it to a default, or the build to set it to the desired target
  version. This is also how `_WIN32_WINNT` works.
- `_WIN32_WCE` default is set by `windef.h` in CeGCC.
- `_WIN32_WCE` isn't set to a default by MSVC Windows CE headers (the
  ones I checked at least).
- CMake sets `_WIN32_WCE=<ver>`, `UNDER_CE`, `WINCE` for MSVC WinCE.
- `_WIN32_WCE` seems more popular in other projects, including CeGCC
  itself. `zlib` is a notable exception amongst curl dependencies,
  which uses `UNDER_CE`.
- Since `_WIN32_WCE` needs "certain" headers to have it defined, it's
  undefined depending on headers included beforehand.
- `curl/curl.h` re-uses `_WIN32_WCE`'s as a self-guard, relying on
  its not-(necessarily)-defined-by-default property:
  25b445e479/include/curl/curl.h (L77)

1a36923d73 tests: change the behavior of swsbounce
- Change the swsbounce keyword to override the part number on a
  subsequent request to the previous part number + 1.

Note the previous part number in this case is the part number that
was returned as a response to the previous request and contained
the swsbounce keyword.

Prior to this change swsbounce incremented the part number of the
subsequent request instead of overriding it, and did so in a more
limited fashion that prevented chaining swsbounce in multiple responses.

For example, if the test makes a request that causes the sws server to
return `<data>` as a response and that response contains `swsbounce`
then for the next response the sws server returns `<data1>`. If
`<data1>` also contains `swsbounce` then for the next response the sws
server now returns `<data2>` instead of the requested part.

Makefile.mk: drop in favour of autotools and cmake (MS-DOS, AmigaOS3)
`Makefile.mk` supported MS-DOS and Amiga, but `./configure` also
supported them in a better tested and more flexible way.

This patch also adds CMake support for MS-DOS/DJGPP and Amiga OS 3.

`Makefile.mk` was not maintained. Delete it in favour of first-tier
build methods.

Also include some non-MS-DOS/AmigaOS-specific tidy-up, see details at
the end of this message.

Details:

- fix/silence all MS-DOS/DJGPP build warnings and issues.
- add MS-DOS support to cmake.
  - default to `ENABLE_THREADED_RESOLVER=OFF` for MS-DOS.
  - add support for `WATT_ROOT`.
  - use static libcurl with MS-DOS.
  - fixup default CMake suffixes/prefixes for DJGPP.
  - disable hidden symbols for MS-DOS. Not supported on MS-DOS.
  - opt-in MS-DOS into `USE_UNIX_SOCKETS`.
- improve MS-DOS support in autotools.
  - default to `--disable-threaded-resolver` for MS-DOS.
- make sure to use `close_s()` (from Watt-32) with autotools and cmake.
  `Makefile.mk` used it before this patch.
- GHA: add DJGPP cmake (~30s) and autotools (~60s) build jobs.
  Also build tests and examples with cmake.
- improve AmigaOS support in autotools:
  - configure: detect `CloseSocket()` when it's a macro.
  - configure: fix `IoctlSocket` detection on AmigaOS.
  - curl-amissl.m4: pass AmiSSL libs to tests/servers.
- add AmigaOS3 support to cmake:
  - cmake: fix `HAVE_IOCTLSOCKET_CAMEL` and
    `HAVE_IOCTLSOCKET_CAMEL_FIONBIO` detections.
  - set necessary system libs.
  - add AmiSSL support.
  - inet_ntop, inet_pton: fix using it for AmigaOS. cmake detects them,
    and they did not compile with AmigaOS.
  - cmake: better sync `gethostname` detection with autotools.
    Fixes detection for AmigaOS, where `gethostname` is a macro.
  - cmake: fix `sys/utime.h` detection on AmigaOS.
  - cmake: force-disable `getaddrinfo` for AmigaOS.
  - cmake: tweak threading and static/shared default for AmigaOS.
  - cmake: rely on manual variable `AMIGA` to enable the platform.
- GHA: add AmigaOS cmake and autotools (~45s) jobs.
  Also build tests and examples with cmake.
- INSTALL: update MS-DOS and AmigaOS build instructions.
- amigaos: fix `-Wpointer-sign` and
  `zero or negative size array '_args'` in `Printf()`.
- amigaos: fix `-Wpointer-sign`
- amigaos: fix `-Wredundant-decls` `errno` and `h_errno`.
- amigaos: brute-force silence `lseek()` size warnings.
- amigaos: server/resolve: silence `-Wdiscarded-qualifiers`.
- amigaos: server/resolve: fix `-Wpointer-sign`.
- amigaos: fix `CURL_SA_FAMILY_T` type.
- nonblock: prefer `HAVE_IOCTLSOCKET_CAMEL_FIONBIO` for AmigaOS.
  `ioctl` is also detected, but fails when used. Make the above override
  it for a successful build.

- configure: sync `ADDRESS_FAMILY` detection signals with cmake.
- doh: use `CURL_SA_FAMILY_T`.
- lib: drop mingw-specific `CURL_SA_FAMILY_T` workaround.
- cmake: extend instead of override check-specific
  configurations/requirements.
  This allows to honor global requirements added earlier.
  Necessary for AmigaOS for example.
- cmake: omit warning on disabled IPv6 for MS-DOS and AmigaOS.
  No IPv6 support on these platforms. Also sync with autotools.
- lib1960: use libcurl `inet_pton()` wrapper.
- cmake: detect LibreSSL (to match autotools).
- cmake: say the specific OpenSSL flavour detected.
- hostip: add missing `HAVE_SOCKADDR_IN6_SIN6_SCOPE_ID` guard.

build: fix MSVC UWP builds
The MSVC UWP job in CI did not actually enable UWP. Fix this and
the fallouts discovered after enabling it.

- GHA/windows: make sure to enable UWP in MSVC vcpkg UWP job.
  Use the CMake options and C flags already used for mingw-w64, but use
  `WINAPI_FAMILY_PC_APP` instead of the deprecated `WINAPI_FAMILY_APP`.
  (The former is not supported by mingw-w64, so leave it there as-is.)
  Follow-up to cb22cfca69 #14077

- GHA/windows: by default the MSVC UWP job became 2x-3x slower than
  others after actually enabling UWP. Most of it is caused by
  CMake/MSBuild automatically building full APPX containers for each
  `.exe` target. This includes 21 CMake feature detections. Each
  detection app is built into a 15MB APPX project, with code signing,
  logos, etc. Example:
    https://github.com/curl/curl/actions/runs/12056968170/job/33620610958
  Disable this overhead for curl build targets via custom
  `CMAKE_VS_GLOBALS` options. I've found no way to apply them to feature
  detection targets, so those remain slow.

- cmake: automatically enable Unicode for UWP builds. It's required.
  Also stop enabling it manually in the existing CI job.

- tests: fix `getpid()` use for Windows UWP:
  ```
  tests\server\util.c(281,21): warning C4013: 'getpid' undefined; assuming extern returning int
  ```
  Ref: https://github.com/curl/curl/actions/runs/12061215311/job/33632904249#step:11:38

- src/tool_doswin: disable `GetLoadedModulePaths()` for UWP.
  mingw-w64 UWP was okay with this, but MS SDK headers are not.
  This makes `--dump-module-paths` return empty for UWP builds.
  ```
  src\tool_doswin.c(620,3): error C2065: 'MODULEENTRY32': undeclared identifier
  src\tool_doswin.c(626,11): warning C4013: 'CreateToolhelp32Snapshot' undefined; assuming extern returning int

  ```
  Ref: https://github.com/curl/curl/actions/runs/12055081933/job/33614629930#step:9:35

  to make it build with MSVC UWP:
  ```
  include\curl\curl.h(143,16): error C2061: syntax error: identifier 'curl_socket_t'
  include\curl\curl.h(143,16): error C2059: syntax error: ';'

  ```

  ```

  ```
  Ref: https://github.com/curl/curl/actions/runs/12055696808/job/33616629610#step:11:38

cmake: allow building tests in unity mode
Makes building tests noticeably faster.

Apply changes/fixes/workarounds to make Unity work:
- rename test variables to avoid collisions or shadowing each other when
  combined into single units.
- add workaround to avoid applying `lib/memdebug.h` overrides to system
  headers declaring/defining `getaddrinfo()`/`freeaddrinfo()` for
  `tests/server/resolve.c`. This replaces a previous workaround that
  worked for that specific source.
- rename test macro `CTRL` clashing with Cygwin `sys/ioctl.h`.
- add include guard to `test.h`.

- exclude `tests/http/clients` which are all single-source. (like
  `docs/examples`.)
