When initializing the Wayland driver, check if the application is being started in, or trying to connect to, a Wayland session and skip to another driver if not. If neither WAYLAND_DISPLAY nor XDG_SESSION_TYPE are set, try to start anyway, and if the Wayland library is missing or no Wayland sessions are started, initialization will fail later in the process as it previously did.
This fixes the case where a Wayland session is running on a different VT, but an application wishes to run via KMSDRM on the current VT.

Hiding the decorations while not unreferencing the frame was a workaround for an internal libdecor use-after-free bug that was fixed some time ago. Revert to unreferencing the window when hiding to ensure that it is properly destroyed.

Previously, if acting on a surface with less than 32 bits per pixel,
this code was placing the pixel value from the surface in the first
few bytes of the Uint32 to be decoded, and unrelated data from a
subsequent pixel in the remaining bytes.
Because SDL_GetRGBA takes the bits to be decoded from the
least-significant bits of the given value, ignoring the higher-order
bits if any, this happened to be correct on little-endian platforms,
where the first few bytes store the least-significant bits of an
integer.
However, it was incorrect on big-endian, where the first few bytes are
the most-significant bits of an integer.
The previous implementation also assumed that unaligned access to a
32-bit quantity is possible, which is not the case on all CPUs (but
happens to be true on x86).
These issues were not discovered until now because
SDLTest_CompareSurfaces() is only used in testautomation, which until
recently was not being run routinely at build-time, because it contained
other assumptions that can fail in an autobuilder or CI environment.

The data device leave function is intended for drag offers, not selections, and the function as was previously written was a no-op.

Battle for Wesnoth apparently relies on being able to disable rendering

If a compositor tries to change the decoration mode when initially creating a window, the hidden flag might not yet be unset if the decoration mode is changed during the initial roundtrip in Wayland_ShowWindow(). As hiding the window destroys the decoration manager object, the hidden flag check is unnecessary, as the decoration configuration listener will never be entered when the window is hidden.

On some system like MacBook Pro Intel with AMD card, asking for the default device will always return the AMD GPU.
This is not an issue for 99% of the case when the renderer context is here to provide the maximum performance level like for game.
However, for video application using GPU for 1 quad and 1 texture, using the discrete GPU for that lead to an important power consumption (4 to 8W), heat increase, and fan noise.
With this patch, I successfully amend ffplay to only use the integrated GPU (i.e. the Intel one), instead of the discrete GPU (i.e. the AMD one).
