819f6ae75b EGL: Ensure the platform extensions exist before using them

b3aa7083e2 x11: Explicitly specify EGL platform 
Mesa's eglGetDisplay() chooses the native EGL platform from
EGL_PLATFORM, limited autodetection, or the build-time default. If that
selects Wayland while SDL is using the X11 video backend, Mesa can treat
the X11 Display pointer as a wl_display and crash during
eglInitialize().

d07d39b0da atomic: Fix infinite recursion in SDL_CompilerBarrier() fallback 
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.

7751494160 atomic: Use DMB ISHLD for aarch64 acquire barrier

c3b0e62850 atomic: Use __atomic_thread_fence() when available 
This avoids requiring inline assembly for each architecture.

It also fixes some weakly ordered architectures which lacked
said inline assembly (RISC-V, MIPS, LoongArch, etc) and were
thus disasterously broken.

c8ebb1456e Backport VIRPIL Controls device IDs to SDL2 
Backport of SDL3 fix (libsdl-org/SDL#15418).

VIRPIL Controls (VID 0x3344) flight sticks are
misclassified as gamepads by SDL's axis-count
heuristic because they report exactly 6 axes,
matching SDL_GAMEPAD_AXIS_COUNT. Adding them to
the appropriate device lists ensures correct
classification.

Tested on Linux (Fedora 43, kernel 6.19) with:
- R-VPC Stick MT-50CM3 (PID 0x4391)
- L-VPC Stick MT-50CM3 (PID 0x8390)
- VPC VMAX Prime Throttle (PID 0x0196)

30de669b32 atomic: Fix missing full memory barrier on GCC/Clang 
__sync_lock_test_and_set() is designed for creating locks, not as
a general atomic exchange function. As a result, it only provides
an acquire memory barrier and isn't guaranteed to actually store
the provided value (though it does on architectures we care about).

__atomic_exchange_n() is supported on GCC/Clang for the last ~10
years, so let's use that instead if available. We will keep the
__sync_lock_test_and_set() fallback around for ancient platforms,
but add a full memory barrier to match the documented behavior.

2d28ee6eb7 CLAUDE.md: Just copy the text from AGENTS.md in here for now. 
Someone mentioned that Claude sees this file's previous text and adds "look at
AGENTS.md" to it's TODO list instead of treating it as the thing it should do
first.

If everything decides to prefer AGENTS.md at some point, we'll delete this
file.

A symlink would apparently also work, but it would be the only symlink in the
SDL git repo, so it seemed less disruptive to just copy the file over for now.

5a9caa7432 CLAUDE.md: added. 
Apparently Claude Code won't read AGENTS.md by default at this moment, but
since that's the direction we're moving, let's just add the file Claude
currently looks for and tell it that the actual instructions are in AGENTS.md.

I thought these things were supposed to be less complicated that interacting
with humans, lol.
