When used together with `USE_OPENSSL`. `USE_QUICHE` always implies
`USE_OPENSSL`.

dnscache: own source file, improvements
- Rename `Curl_resolv_unlink()` to `Curl_dns_entry_unlink()`.
- Change `Curl_dnscache_get()` to return CURLcode result. Returns
  now `CURLE_COULDNT_RESOLVE_HOST` for "negative" cache entries.
- Add `Curl_dnscache_add_negative()` to put a "negative" entry
  into the cache.

OpenSSL: check reuse of sessions for verify status
OpenSSL records its peer verification status inside its SSL_SESSION
objects. When a session is later reused, the SSL connection inherits
this verify status.

Session keys prevent reuse of sessions between connections that verify
the peer and those who do not. However, when Apple SecTrust is used
to verify a connection, this does not update the Sessions verify
status (and there is no setter). On session reuse, OpenSSL fails
the verification and Apple SecTrust cannot verify either since the
certificate peer chain is not available.

Fix this by checking the verification status on session reuse and
remove the session again if the peer needs to be verified, but the
session is not.

pytest: improve stragglers
A fix for the tests that took the longest:
- test_05: make the server close the HTTP/1.1 connection when
  simulating an error during a download. This eliminates waiting
  for a keepalive timeout
- test_02: pause tests with slightly smaller documents, eliminate
  special setup for HTTP/2. We test stream window handling now
  elsewhere already
- cli_hx_download: run look in 500ms steps instead of 1sec, resuming
  paused tranfers earlier.

build: stop overriding standard memory allocation functions
Before this patch curl used the C preprocessor to override standard
memory allocation symbols: malloc, calloc, strdup, realloc, free.
The goal of these is to replace them with curl's debug wrappers in
`CURLDEBUG` builds, another was to replace them with the wrappers
calling user-defined allocators in libcurl. This solution needed a bunch
of workarounds to avoid breaking external headers: it relied on include
order to do the overriding last. For "unity" builds it needed to reset
overrides before external includes. Also in test apps, which are always
built as single source files. It also needed the `(symbol)` trick
to avoid overrides in some places. This would still not fix cases where
the standard symbols were macros. It was also fragile and difficult
to figure out which was the actual function behind an alloc or free call
in a specific piece of code. This in turn caused bugs where the wrong
allocator was accidentally called.

To avoid these problems, this patch replaces this solution with
`curlx_`-prefixed allocator macros, and mapping them _once_ to either
the libcurl wrappers, the debug wrappers or the standard ones, matching
the rest of the code in libtests.

This concludes the long journey to avoid redefining standard functions
in the curl codebase.

Note: I did not update `packages/OS400/*.c` sources. They did not
`#include` `curl_setup.h`, `curl_memory.h` or `memdebug.h`, meaning
the overrides were never applied to them. This may or may not have been
correct. For now I suppressed the direct use of standard allocators
via a local `.checksrc`. Probably they (except for `curlcl.c`) should be
updated to include `curl_setup.h` and use the `curlx_` macros.

This patch changes mappings in two places:
- `lib/curl_threads.c` in libtests: Before this patch it mapped to
  libcurl allocators. After, it maps to standard allocators, like
  the rest of libtests code.
- `units`: before this patch it mapped to standard allocators. After, it
  maps to libcurl allocators.

Also:
- drop all position-dependent `curl_memory.h` and `memdebug.h` includes,
  and delete the now unnecessary headers.
- rename `Curl_tcsdup` macro to `curlx_tcsdup` and define like the other
  allocators.
- map `curlx_strdup()` to `_strdup()` on Windows (was: `strdup()`).
  To fix warnings silenced via `_CRT_NONSTDC_NO_DEPRECATE`.
- multibyte: map `curlx_convert_*()` to `_strdup()` on Windows
  (was: `strdup()`).
- src: do not reuse the `strdup` name for the local replacement.
- lib509: call `_strdup()` on Windows (was: `strdup()`).
- test1132: delete test obsoleted by this patch.
- CHECKSRC.md: update text for `SNPRINTF`.
- checksrc: ban standard allocator symbols.

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: avoid overriding system symbols for fopen functions
By introducing wrappers for them in the curlx namespace:
`curlx_fopen()`, `curlx_fdopen()`, `curlx_fclose()`.

The undefine/redefine/`(function)()` methods broke on systems
implementing these functions as macros. E.g. AIX 32-bit's `fopen()`.

Also:
- rename `lib/fopen.*` to `lib/curl_fopen.*` (for `Curl_fopen()`)
  to make room for the newly added `curlx/fopen.h`.
- curlx: move file-related functions from `multibyte.c` to `fopen.c`.
- tests/server: stop using the curl-specific `fopen()` implementation
  on Windows. Unicode isn't used by runtests, and it isn't critical to
  run tests on longs path. It can be re-enabled if this becomes
  necessary, or if the wrapper receives a feature that's critical for
  test servers.

tls: CURLINFO_TLS_SSL_PTR testing
Add tests of CURLINFO_TLS_SSL_PTR and its returned value in test client
'hx-download'. Use obtained pointer to look up the negotiated TLS

Update manpage of CURLINFO_TLS_SSL_PTR to also describe the behaviour of
wolfSSL similar to OpenSSL. Fix the wolfSSl implementation for TCP to
behave like that. Update the QUIC queries.

Fix rustls `get_internals()` to return the rustls_connection* and not

tests: merge clients into libtests, drop duplicate code
libtests and clients were built the same way after recent overhauls.
libtests are used by runtests, clients by pytests.

Merge clients into libtests, aligning their entry function signature,
dropping common utility functions, and simplifying the build.

Note: After this patch `CURLDEBUG` applies to cli tests, when enabled.

Also:
- lib552: drop local copy-paste debug callback in favor of testtrace.
- lib552: drop local copy-paste dump function in favor of testtrace.
- clients: use `long` for HTTP version, drop casts.
- clients: replace local dump function in favor of testrace clone.
- sync cli test entry function prototype with libtests'.
- h2_serverpush: replace local trace callback with testtrace.
- de-duplicate 3 websocket close, ping, ping, functions. Kept the pong
  iteration from `ws_pingpong`. Note: the pong clone in `lib2304` was
  returning an error when `curl_ws_recv()` returned non-zero and
  the payload matched the expected one anyway. After this patch, this
  case returns success, as it does in `ws_pingpong`.
  `lib2304` keeps passing, but I'm not sure if the previous behavior
  was intentional.
- display full value in websocket close, ping, pong, drop casts.
