This reverts commit 1e016fd5ea.
In order to use low latency mode, you need to set low latency callbacks. This has always been recommended and is apparently required on Android 15. SDL3 has these implemented correctly but SDL2 does not, so we should revert this for now.

This reverts commit 120b8d4189.
The issue this was patching over in Vanilla-Conquer was the lack of an exposure event when showing a window, which has since been remedied.
Attaching EGL window objects can also cause protocol violations now that the explicit sync protocol is in use, if SDL creates one and then the client tries to attach one itself, so they really shouldn't be created unless the client specifically requested it.
Suppose host has some three-finger gesture. Then we get the following sequence
of events:
DOWN-DOWN-DOWN-MOTION-CANCEL
Note that there is no UP in this sequence. So if we don't handle CANCEL then
we end up thinking that fingers are still touching the screen. Ideally we
should inform the application that cancel has happened as not to trigger
spurious taps but still this is way better than being stuck with phantom
finger touch.
UpdateDevice() can be called at an arbitrary rate, so we need to
pace ourselves to avoid filling up the rumble queue with these.

Modern kernels (v5.8+) allow non-root usage of drmDropMaster(), so
we can hold on to our fd after dropping master on it. This fixes
populating drm_fd in the KMSDRM SysWMinfo when using Vulkan.
Also add a missing error check for open() while we're here.
This used a tiny stack, which apparently upsets Blender for various
technical reasons. Instead, just use the default stack size, which should
give it plenty of space to work.
If the thread failed to create, we would then wait on a semaphore that would
never trigger, so don't do that anymore!
Fixes#10806.

On most Unix platforms supported by SDL, the canonical name used to load
a library at runtime includes its ABI major version, and the name
without a version is not guaranteed to exist on non-developer systems.
libX11-xcb.so.1 is correct on Linux, and probably on other Unix
platforms like FreeBSD.
A notable exception is OpenBSD, which apparently does not use
ABI-suffixed names, so continue to use libX11-xcb.so there.

We make sure we initialize XInput first, so that anything checking whether it's enabled gets a valid result based on whether we were able to load it or not.

Send the fake warp coordinates when emulating warps with relative mode to ensure that it appears that the cursor is always reset to where the application expects it to be.
Fixes cases where games can continue moving the camera if the mouse is lifted during motion.
Cursor visibility in the SDL input layer only reflects whether ShowCursor/HideCursor was called. In the case of relative mode, the cursor can be hidden, but the SDL_Mouse visibility flag will be true.
Track cursor visibility separately in the X11 driver. Fixes the cursor becoming visible when using the warping relative mode with XWayland.
