Register the destroyed callback to handle cases where the IC is suddenly no longer valid (e.g. if ibus or fcitx dies).

If the previous selection offering was recursive, a nil selection should be ignored, or clearing the clipboard may clear the backing memory of the client's selection offering as well.
(cherry picked from commit cc2713c047)
The wl_fixes.ack_global_remove request signals the compositor that the
client will not bind the removed global. It can be used by the
compositor to decide when it is safe to actually destroy the
corresponding global. If a global is destroyed too soon, some clients may
get disconnected.

Some window managers will mark minimized or offscreen windows as unmapped. When hiding a window, unconditionally call XWithdrawWindow, and don't wait for an UnmapNotify event if the window is already in the unmapped state, or it will block indefinitely waiting for an event that never arrives.
(cherry picked from commit e442a9a5e1)
A fullscreen exit event doesn't always accompany an entry error, so ensure that all relevant state is cleared if the window fails to enter fullscreen.

The PS3 probing switches the HORI Horipad Mini into Nintendo Switch report mode, which we don't recognize since it's still using the Xbox 360 endpoint.

Generate activation tokens for new windows when necessary, and check the hint for activating windows when shown. This will allow new windows to correctly take focus in environments with elevated focus stealing prevention when possible, and it will try to prevent new windows from being activated if the hint is set to false.

We don't care _what_ the `sizeof` results are, we just want it to vaporize
the condition's code out of the build. So we check it with a `? 1 : 0`, so it
always boils down to a `sizeof (int)`, no matter what data type the condition
actually is.
This works with bitfields, pointers, anything that can be "truthy." If it
isn't truthy, it would fail when assertions are enabled anyhow.
Fixes#15990.

Before, MetalFence was implemented as simply a busy loop on an atomic
int on metal, meaning the cpu would busy wait on the gpu to finish
taking power from it and decreasing battery life. This was the only kind
of cpu-gpu syncing (apart from requesting a swapchain)
