Replace result code `CURLE_SSL_CIPHER` with
`CURLE_BAD_FUNCTION_ARGUMENT` in case of a low-level digest function
fails. Functionality is related to vauth, not SSL, and the operation is
a digest, not a cipher.
Also fix a indentation.

Drop redundant `#undef`s, casts, `#endif` comments, includes, drop
intermediate variables, sync include and macro order.

Macros have been deleted upstream and never defined in OpenSSL 1.1.0+:
474e469bbd
BoringSSL deleted the last internals uses in 2014:
457112e197
LibreSSL refers to them internally and in two public headers, but never
set them via `openssl/opensslfeatures.h` / `openssl/opensslconf.h`.

- asyn-thrdd.c: scope an include.
- apply more clang-format suggestions.
- tidy-up PP guard comments.
- delete empty line from the top of headers.
- add empty line after `curl_setup.h` include where missing.
- fix indent.
- CODE_STYLE.md: add `strcpy`.

To make it available for all files. Drop includes from individual
sources. This header was already included from most sources and not
specific to any internal subsystem.
Also to ensure that two system symbol redefines on Windows (`read()` and
`write()`) get applied to all sources. Move them to `curl_setup.h`.
Closes#20056
- curl_range: replace `sendf.h` with direct header dependency
`curl_trc.h`.
- drop `curl/curl.h` includes from internal sourcees in favor of the
include made from `curl_setup.h`. Replace it with the latter where
it's the only include.
- include `curl_setup.h` before using macros, where missing.
- drop redundant `stdlib.h`, `string.h` includes, in favor of
`curl_setup_once.h` including them.
- drop redundant `limits.h` in favor of `curl_setup.h` including it.
- fake_addrinfo.h: fix typo in comment.
- curl_setup_once.h: drop `stdio.h` in favor of earlier include in
`curl_setup.h`.
- drop stray, unused, `stddef.h` includes.
- memdebug.h: add missing `stddef.h` include. (relying on accidental
includes via other headers before this patch.)
- stddef.h: document why it's included.
- strerr: drop `curl/mprintf.h` in favor of `curl/curl.h` including it
via `curl_setup.h`.

It also means that all supported OpenSSL versions and forks support
TLSv1.3 after this patch.
It reduces `openssl.c` size by more than 10%, or 400 LOC.

- dllmain, curl_sha512_256: formatting.
Closes#18387
These libraries do not support TLS 1.3 and have been marked for removal
for over a year. We want to help users select a TLS dependency that is
future-proof and reliable, and not supporting TLS 1.3 in 2025 does not
infer confidence. Users who build libcurl are likely to be served better
and get something more future-proof with a TLS library that supports
1.3.
Closes#16677
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.

To reduce the number `-Wunused-macro` compiler warnings:
- delete unused macros.
- comment out unused macro that are part of a set.
- move macros into the scope they are used.
This may be useful to enable by default, but there are tricky cases that
I didn't manage to fix and paused the effort. E.g. internal features
checks in `openssl.c`. There is more, once those are fixed.
Closes#16279
- drop version guard for `__inline`.
Supported since `_MSC_VER` 1000.
Visual C++, 32-bit, version 4.0 (1996)
- drop version guard for `__declspec(noreturn)` and `__forceinline`.
Supported since `_MSC_VER` 1200.
Visual C++, 32-bit, version 6.0 (1998)
For ancient versions, it's possible to override the default behaviour
by setting these macros via `CPPFLAGS`: `CURL_NORETURN`, `CURL_INLINE`,
`CURL_FORCEINLINE`
Closes#15946
Instead of redefining the `inline` keyword, introduce curl's own
`CURL_INLINE` macro and set it depending on the compiler's capabilities,
or use its value set via custom C flags.
Also keep honoring a custom `inline` macro, if set.
Closes#15523
`SHA512_256_BLOCK_SIZE`, `SHA512_256_DIGEST_SIZE` macros were both
defined within curl and also in the nettle library required by GnuTLS.
Fix it by namespacing the curl macros.

This is a follow-up for PR #12897.
