I updated .clang-format and ran clang-format 14 over the src and test directories to standardize the code base.
In general I let clang-format have it's way, and added markup to prevent formatting of code that would break or be completely unreadable if formatted.
The script I ran for the src directory is added as build-scripts/clang-format-src.sh

Vista and later provide the SleepConditionVariableCS() function for this.
Since SDL_syscond_srw.c doesn't require SRW locks anymore, rename it to
SDL_syscond_cv.c which better reflects the implementation of condition
variables rather than the implementation of mutexes.
Fixes#4051.
When SleepConditionVariableSRW() releases the SRW lock internally, it causes
our SDL_mutex_srw state to become inconsistent. The lock is unowned yet inside,
the owner is still the sleeping thread and more importantly the owner count is
still 1.
The next time someone acquires the lock, they will bump the owner count from 1
to 2. At that point, the lock is hosed. From the internal lock state, it looks
to us like that owner has acquired the lock recursively, even though they have
not. When they call SDL_UnlockMutex(), it will see the owner count > 0 and not
call ReleaseSRWLockExclusive().
Now when someone calls SDL_CondSignal(), SleepConditionVariableSRW() will start
the wakeup process by attempting to re-acquire the SRW lock. This will deadlock
because the lock was never released after the other thread had used it. The
thread waiting on the condition variable will never be able to wake up, even if
the SDL_CondWaitTimeout() function is used and the timeout expires.
Is automatically used when the SRW SDL_mutex implementation is active.
Otherwise falls back to the generic implementation.
v2: - Rebase onto master fa3ea1051a4b
v2: - Add SRW definitions as suggested by Ozkan Sezer
Allows building against older platform headers.
- Rename "hidden" function parameter `mutex_` to `_mutex`
v3: - Use GetModuleHandle instead of LoadLibrary
- Fix typo in comment
WinRT 8.0 (Phone and non-Phone) didn't offer an API to set an already-created
thread's priority. WinRT 8.1 offered this API, along with several other
Win32 thread functions that were previously unavailable (in WinRT).
This change makes WinRT 8.1+ platforms use SDL's Win32 backend.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
