The new protocol adds support for more native communication of
fractional scaling.
Everything in the wayland backend already existed only our fractional
scale was calculated implicitly through a combination of output size
guesswork for fullscreen windows.
This new protocol makes that explicit, providing a more robust solution
and a solution for non-fullscreen surfaces. The fallback code is still
left in place for now whilst compositors gain support.
- do not overwrite error message set by SDL_InitFormat (SDL_AllocFormat)
- set proper error message (Cocoa_Metal_CreateView)
- protect against allocation failure (UIKit_Metal_CreateView)
(cherry picked from commit cf0cb44df8)
- SDL_CreateMutex returns NULL when the creation fails (ngage)
- SDL_SemValue returns 0 when the semaphore is NULL (n3ds)

`argv[0]`/`getexexname()` are not always absolute paths by default and can be modified to anything the developer wants them to be.
Consider using `readSymLink("/proc/self/path/a.out")` instead and `getexecname()` as the fallback, since the symlink will always be the correct absolute path (unless /proc is ot mounted, but it is by default on Solaris and Illumos platforms).

Explicitly include the Wayland protocol headers when statically linking against the Wayland libraries or older system headers might be used instead of the local versions.
(cherry picked from commit 836eb22442)
The typedef seems to be pulled in coincidentally with newer SDKs, but
older ones need to import the header explicitly.

This reverts commit 33a68f575f.
We don't want the G29 to show up as a gamepad, Steam will create a virtual Xbox controller for it, which breaks racing games.
When changing the window state from non-floating to floating (e.g. leaving fullscreen), libdecor can send bogus content sizes that are +/- the height of the window title bar and start 'walking' the window height in one direction or the other with every transition.
The floating window size is known, so use the cached value instead of the size reported by libdecor when restoring the floating state.
Some applications (and embarrassingly, testime is one of them) call
SDL_StartTextInput() or SDL_SetTextInputRect() every frame. On KDE/KWin
with fcitx5, this causes there to be several preedit events every frame
(particularly given some of the workarounds in Wayland_StartTextInput),
which slows testime down to an unusable crawl.
Instead, make SDL_StartTextInput() a no-op if text input is already
enabled, and cache the input rect, only changing it when the new rect is
actually different.
With these changes, we only get preedit events (and hence
SDL_TEXTEDITING events) when the preedit string actually changes. This
matches the behaviour under XWayland, and works very smoothly.
