This fixes faults when loading from read-only memory and avoids
cache line bouncing across cores which reduces performance.

Now this keeps one FBO for each SDL_TEXTUREACCESS_TARGET texture, and doesn't
reuse it. We check if the FBO is "complete" once, at creation time, and
setting a render target merely has to bind the right FBO and never look back.
This simplifies the code and removes a guaranteed pipeline stall when setting
a new render target.
Fixes#15524.

Some compositors may dispatch this too early, during the initial empty commit, when subsurfaces are attached to a toplevel window, but a buffer has yet to be committed to the parent surface. Don't set the frame callback until the initial empty commit is done, so it will be called when the actual parent surface frame is committed.
(cherry picked from commit e3393e6304)
Some compositors send the frame callback as part of the initial configuration sequence, so the window may already be past the "waiting for frame" state. Ensure that the exposure event is always sent.

Under the right conditions, this extension can result is smoother resizing when rendering with OpenGL, however, it is known to cause problems in certain cases, such as when handling presentation externally.
Gate it behind a hint, and disable it by default. Developers can selectively enable it when they verify that they meet the criteria for using it, and that it behaves correctly in their apps/games.

If the cursor was created with a temporary surface that was pointing at external memory, then when the cursor is used it might be referencing memory that had already been freed.

This was added so that the new thread definitely has its threadid set, via
SDL_GetCurrentThreadID(), before SDL_CreatThread returns, but this broke
Emscripten, which can't wait on a newly-created thread, since the thread won't
start until a later mainloop iteration.
Now we have the creating thread set this id in SDL_SYS_CreateThread, where
platform-specific logic can figure out how to calculate the new thread's ID
from the parent thread, without using SDL_GetCurrentThreadID().
Fixes#15509.

Natural scrolling affects both axes, and the compositor may not send the vertical axis orientation if the frame has no vertical scroll motion, so purely horizontal events need to be flagged as inverted as well.

controller.vendorName returns a generic name for Xbox controllers ("Controller"), so we have to give them proper names.

The code is using `controls.window` before checking if it isn't null.
I found this bug by accident when I tried to run `SDL_ShowSimpleMessageBox`.
It first tried using Wayland with `zenity`, but since I don't have `zenity`, it fallbacked to `X11_ShowMessageBoxImpl`.
For some reason it couldn't create a window, maybe something related to XWayland, so `controls.window` was `NULL`.

Without this lock, a concurrent call to SDL_ReleaseGPUBuffer, SDL_ReleaseGPUTransferBuffer or SDL_ReleaseGPUTexture can cause one of the arrays to be reallocated while METAL_INTERNAL_PerformPendingDestroys is iterating over it, causing a bad day all around.

Only parse when necessary, which it isn't when opening a file, so this is now
separated from creating the cached AAssetManager object.
(cherry picked from commit 9235ac4efd)
The AAssetManager won't supply this information to us, but it's just a zip
file, so we can read its central directory ourselves. We can still use
AAssetManager for file i/o to the APK's assets, so we don't have to deal with
compression and other zipfile features.
Fixes#15220.

- Add missing SDL_MemoryBarrierRelease() in the generic codepath
- Remove MSVC x86/x64 case which is now identical to the generic codepath
- Fix Solaris barrier to ensure prior stores are visible before unlocking
(cherry picked from commit 95ae0c194e)
On some platforms, SDL_MemoryBarrierRelease() is defined to
SDL_CompilerBarrier(). If SDL_CompilerBarrier() is also defined to
the fallback spinlock acquire/release, then we will infinitely
recurse in SDL_UnlockSpinlock(). Avoid this by not unlocking the
temporary spinlock we create.
