Terminate the block of environment variables with NUL. Previously the block was left unterminated which could cause subprocess spawn failures depending on the array contents after the last item.
The feature test macro is nonstandard and not available on older GCC
version, which causes build failure despite the compiler does support
__builtin_mul_overflow.
Since there are no fallback when __builtin_mul_overflow is not
available, there is no need to check, so simply remove it.
If __builtin_mul_overflow is not supported compilation will still fail
just like currently.
The XDG Base Directory specification says “All paths set in these
environment variables must be absolute. If an implementation encounters
a relative path in any of these variables it should consider the path
invalid and ignore it.”
Add a new MP_CKD_MUL macro which does a multiplication with overflow
checking, backed by either the C23 ckd_mul standard function, or the
GCC/Clang __builtin_mul_overflow otherwise.
Currently, all fopen uses in mpv do not set cloexec flag, resulting
in fd leak whenever mpv creates a process.
This makes mpv use mp_fopen on all platforms, and always set O_CLOEXEC
on the opened fd. This is required because the "e" flag for fopen is
nonstandard and UB in C11, and unsupported on macOS.
This had been done similarly in other projects. e.g.

The previous commit to dynamically load VapourSynth R74 would fail to work
for VapourSynth R73 and before on Linux due to load mode RTLD_LOCAL. To
make it work on all VapourSynth version, switch to use RTLD_GLOBAL mode.
This unifies --drag-and-drop handling to a single place. All platforms
currently only support normal drop (mapped to "replace") and shift click
drop (mapped to "append").

Add library handle closing in drv_vss_uninit for completeness.
VapourSynth R74 changed two things relevant to mpv build process:
1) VSScript no longer has static library to link to, and only support runtime loading.
This is reflected on the new VSScript example in VapourSynth SDK.
2) The VSScript library name is changed from libvapoursynth-script to libvsscript for Linux
and MacOS.
The new VSScript initialization code is modified from their SDK example to utilize
mpv's mechanisms. Build dependency is also updated accordingly.
The dynamic allocation of this strings is completelly pointless. It adds
complexity with mp_exec_once to init aexit() to free the string, which
was leaked anyway, because the structure is thread_local and atexit only
data from the main thread was freed.
Remove all this, and just use static buffer.
Move PathCchRemoveFileSpec after actually getting the file size. It must
have been swapped at some point by accident.
Also use correct unit for the size.

The system preferred language is the language used during Windows
install. It doesn't have much purpose except that it is the backend
language for core Windows internals. All user facing dialogs and text
should follow the user preferred language, as this is what the user
selected and uses on daily basis.
It makes no sense to include system language in track selection.
Commit baf2fd2f28 fixed this for 2nd call
to GetSystemPreferredUILanguages(), but apparently regressed the 1st
call, duh.
To retrieve the size both buffer has to be NULL and size 0.
Memory has a lot of zeros, because it has been working quite
consistently on CI.
duration and position properties were observed as double which lead to a
lot of updates per second (high granularity). it is recommended to not
update the position of the touchbar too frequently, why we had a manual
1 second rate limit.
instead of manually rate limiting the property, just observe it as int64
which only updates every second. it also causes a bit less pressure for
our core.

since we have a mapping layer between vulkan and metal (MoltenVK) we
don't actually know which colorspace is used/mapped to.
log colorspace changes to actually see which colorspace was chosen.

those 9 formats are valid for a CAMetalLayer.

This ensures that we test format string for the actual impl that is
being used. Depending if UCRT is used and if __USE_MINGW_ANSI_STDIO is
defined the implementation capabilities may differ.
Note that we don't explicitly define __USE_MINGW_ANSI_STDIO anymore,
this is defined implicitly in mingw headers, if needed. We don't support
ancient mingw versions that does not define it correctly for c11.
Some protocols may not exist, add them so the mapping to url handler
works correctly. Note that protocols are not removed, only the handler
is. They will remain unassociated, after unregister.

UniformTypeIdentifiers is only available since macOS 11.
added in 6b0e4f7 and #15859.
guard the allowedContentTypes UTType property of the NSOpenPanel and
add a dummy struct UTType and dummy allowedContentTypes property on
macOS versions that don't have those available.
currently we use the withLock function with NSCondition and NSLock,
which are not available on swift versions lower than 5.7. we only added
compatibility fallbacks for NSCondition though. introduced in 1364c80
and #14334.
instead of only adding the fallback to a specific class add it to the
whole protocol all the locking classes use, similar to the actual
implementation.
