Add tweak for mingw-w64 when building tests/http/client programs to
avoid a bogus `-Wformat` warning when using mingw-w64 v7.0.0 or older.
The warning is bogus because these programs use curl's `printf()`
implementation that is guaranteed to support that format spec.
Add this for both CMake and autotools. (But only CMake is CI tested with
an old toolchain.)
Apply the workaround to `docs/examples`, and fix an example to use
curl's `printf()` with `CURL_FORMAT_CURL_OFF_T`.
Reintroduce curl `printf()` calls into `tests/http/client`, via #14625.
Also restore large number masks to a printf, changed earlier in #14382.

Sources used `lib/curlx.h` with both `ENABLE_CURLX_PRINTF` set and unset
before including it.
In a cmake "unity" batch where the first included source had it unset,
the next sources did not get the macros requested with
`ENABLE_CURLX_PRINTF` because `lib/curl.x` had already been included
without them.
Fix it by by making the macros enabled permanently and globally for
internal sources, and dropping `ENABLE_CURLX_PRINTF`.
This came up while testing unity builds with smaller batches. The full,
default unity build where all `src` is bundled up in a single unit, was
not affected.
Fixes:
```
$ cmake -B build -DCMAKE_UNITY_BUILD=ON -DCMAKE_UNITY_BUILD_BATCH_SIZE=15
$ make -C build

This changes the wording to say that 1 should be returned instad of
non-zero to return error from the callback. I did this to simplify, even
if other non-zero values still do the same thing I figure we might just
as well just leave out the others from the documentation.

Closes#14637
This value tells how many sources files to bundle in a single "unity"
compilation unit.
The CMake default is 8 sources, curl's CMake set this to 0, meaning
to bundle all sources into a single unit.
This patch makes it possible to override the 0 value, and potentially
optimize the build process further by better utilizing multiple cores
in conjunction with `make -jN`.
The number of sources in lib is 172 at the time of writing this. For
a 12-core CPU, this can give a job for them all:
`-DCMAKE_UNITY_BUILD_BATCH_SIZE=15`
(Compile time may be affected by a bunch of other factors.)
Closes#14626
Drop `find_package(libssh CONFIG)` detection method in favour of
the Find module that supports both `pkg-config`, and CMake-native
(since #14555) detection.
This aligns `libssh` detection with other dependencies. It makes the
build honor custom configuration via `LIBSSH_INCLUDE_DIR`,
`LIBSSH_LIBRARY`.
Also enable libssh in a GHA/macos cmake job for build coverage.
Fixing:
- curl-for-win requiring a hack to configure libssh:
4f9acbed92/curl.sh (L255-L263)
- after #14555, GHA/windows gnutls vcpkg job no longer auto-detected
libssh, due to a regression missing to enable libssh when
found via `find_package(libssh CONFIG)`.

Tested via #14614Closes#14617
For libssh, it fixes a "unity" build issue where libssh deprecation
warnings were not suppressed before this patch, because the suppression
macro was only set before just one of the two `libssh.h` includes.
If the other was compiled first in unity mode, the warnings appeared.
Seen in local curl-for-win build (`CW_CONFIG=test-x64-libssh-quictls`)
with libssh 0.11.0. (Also in a GHA/macos cmake job upcoming in #14614)
Use this opportunity to drop duplicate SSH header includes from the SSH
modules. It's enough to include them via the common `ssh.h` header.
Closes#14612
POSIX sed doesn't support extended regular expressions, so convert a
call to the basic format. This caused a problem on AIX. Also, use the
detected sed binary name instead of hard-coding one.
Change TLS proto version on the test httpd server to test setting
combinations of --tls13-ciphers and --ciphers.
To not let the changed config of the httpd server bleed into the next
test, clean and reload on each test. Because a reload is slow, only
do this if the config is different than the loaded config. For this
the httpd.reload_if_config_changed() method is added.
Overloading of autouse fixtures does not seem to work. For the test
httpd server to be reloaded with a clean config in test_18_methods,
to not be affected by the config changes in test_17_ssl_use, the two
class scope fixtures of test_18_methods are now combined.

With mbedTLS if the minimum version of TLS is set to 1.3,
MBEDTLS_SSL_VERIFY_OPTIONAL is not available in client mode. See:
https://github.com/Mbed-TLS/mbedtls/blob/2ca6c285/library/ssl_tls.c#L1357
Also, there might be plans to remove it completely in future mbedTLS
versions.
Switch to always use MBEDTLS_SSL_VERIFY_REQUIRED. If verifypeer or
verifyhost are disabled the corresponding error flags are cleared in the
verify callback function. That is also where verification errors are
logged.
Closes#14591
For: libgsasl, libidn2, libssh, libuv.
The new Find modules retain using `pkg-config` natively, not as a "hint"
for the CMake-native detection. Of the pre-existing Find modules, only
FindNettle, and FindGSS (with customized code) work this way. Align
detection code for the new modules and add version detection for the
CMake-native paths.
Also, add CMake-native detection for `libgsasl`.
The remaining outlier in `CMakeLists.txt` is GnuTLS, which has
a CMake built-in Find module, but which lacks `pkg-config` support,
required for vcpkg. It remains unchanged.
Another part-outlier is `libssh`, which keeps requiring the trick
`find_package(libssh CONFIG QUIET)` for reasons I could not yet figure
out.
Closes#14555
The original patch added the Find module and CMake option. But the logic
missed a `find_package(MSH3)` call to use that Find module, leaving the
referenced `MSH3_INCLUDE_DIRS`, `MSH3_LIBRARIES` variables undefined.
Blind fix.

Limits `pkg-config` to UNIX and MSVC with vcpkg, by default. Compared to
curl 8.9.1, this unlocks `pkg-config` on MSVC with vcpkg.
This condition might be updated in the future depending on where
`pkg-config` can be useful without breaking things. (e.g. to non-cross
MINGW, or all MINGW).
In the meantime everyone is free to override the default and test their
build with `pkg-config` by setting the `CURL_USE_PKGCONFIG=ON` CMake
option.

Our convention for naming Find modules (the part after the `Find`
prefix, also called as 'package name') is:
Always start with uppercase. Follow with lowercase, unless there is
a clear preference for a stylized name. E.g. the project itself uses it
that way with a matching `<Name>Config.cmake` file, or we use it that
way elsewhere, or the name is an acronym.

- fix BearSSL warning about name mismatch.
- fix Nettle Find module not found on Linux.
- tidy-up: drop quotes from a package name.
Package names must match case-sensitively to work on all platforms:
- `find_package(<NAME> ...)` in `CMakeLists.txt`.
- `CMake/Find<NAME>.cmake` filenames.
- `find_package_handle_standard_args(<NAME> ...` in Find modules.
- `message(STATUS "Found <NAME> ...` in Find modules.
(to match the message shown by `find_package_handle_standard_args()`)

-Wformat-overflow is not a warning that we want enabled as it does not
help us. It can only bring us false positives since it warns on bad uses
of sprintf and vsprintf ("that might overflow the destination buffer").
Two functions we explicitly ban in curl code.
The only way this flag triggers warnings in curl code is false positives
for functions we have marked with the CURL_PRINTF() macro.
Further: it seems -Wformat-trunaction option might in turn also enable
-Wformat-overflow, so if this second option is used, we need to
explicitly set -Wno-format-overflow - not just skip setting
-Wformat-overflow.
