It's reasonable to assume that any of them might need a display and an
audio backend. We run them with SDL_VIDEODRIVER and SDL_AUDIODRIVER
set to dummy anyway.

If a specific audio driver was requested for testing, don't loop over all drivers in the init, open/close, and pause/unpause tests.
Additionally, drivers can fail if attempting to open an audio device when no underlying output is present, which is a valid case if the system has no audio hardware available. Check for the presence of audio output devices before attempting to open them.
Fixes automated tests with various drivers on Windows and Linux.
If the error behaviour in one of these cases was wrong, that could have
been hidden by the error indicator remaining set from a previous test.

A surface of width (0x7fff'ffff) / 2 = 0x3fff'ffff is not quite large
enough to make the pitch overflow in the way we wanted to test here:
with a 32-bit format, that makes each row 0xffff'fffc bytes, which
(just) fits in a 32-bit unsigned size_t. Increasing it to 0x4000'0000
pixels per row is enough to trigger the overflow we intended to test.
In SDL 2, this test bug was hidden by the fact that allocating
0xffff'fffc bytes on a 32-bit platform is very likely to fail, and SDL 2
reported both "malloc() failed" and "this amount of memory is too large
for a size_t" with the same error code.

Adding 3 bytes of alignment to 0x7fff'ffff is not enough to make it
overflow a 4-byte unsigned size_t, so this test was not exercising
the intended failure mode. We cannot actually make this overflow
with a signed 32-bit width and an 8-bit format: the maximum width is
not enough to achieve that. However, if we switch to a 24-bit format,
we can make the calculation overflow.
In SDL 2, this test bug was hidden by the fact that allocating
0x7fff'ffff bytes on a 32-bit platform will usually fail, and SDL 2
reported both "malloc() failed" and "this amount of memory is too large

AUDIO_F32 is an alias for AUDIO_F32LSB, 32-bit floating point with least
significant byte first, resulting in audio_resampleLoss() failing on
big-endian machines. This particular test generates a buffer with
native-endianness float values, so it ought to be using AUDIO_F32SYS,
which is 32-bit floating point in the native endianness.
Already fixed by commit 47bcb078 "Fixed some incorrect SDL_AUDIO_F32 uses"
on the SDL 3 branch.

We can't rely on irrational numbers like pi being represented exactly,
particularly when compiling for i386, where the i387 floating-point
interface carries out calculations in registers that have higher
precision than the actual double-precision variable. The 1980s were a
strange time.

If testautomation is running with only a specific audio driver enabled, we shouldn't try to open other ones, as they might fail.

Changes to the SDL3 video system required some changes to the test suite since the video system always reports the true window size and position.
While SDL2 doesn't directly require these changes, they are needed for SDL2-Compat and committed here to keep the two test suites in sync.
Don't do it in POST_BUILD to avoid multiple parallel builds
stepping on each others toes.
Also don't use copy_if_different, but unconditionally copy it.
The build system should take care of dependencies.

Mesa and Nvidia handle it differently, and one or the other may fix their
implementation in the future, so test which way it works at runtime.
Reference Issue #8004.

Error messages are not part of the ABI, so we can't validate those.
Technically SDL_AllocFormat() on a FOURCC format in SDL2 should fail, but SDL3 supports it and we don't expect SDL2 applications to actually do this, so skip that test.

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
This fixes:
