find_lib() uses sort -V, which is a GNU extension. Users of non-GNU
operating systems should either install GNU coreutils (assumed to
provide a gsort executable), or use the CMake build system.

Clang 15 makes implicit function declarations fatal by default which
leads to some configure tests silently failing/returning
the wrong result.

This fixes linking to SDL2::SDL2-static on systems where external libraries such as X11 are not in a standard location.
Pthread also needs special care.
When minimizing a window, we get this sequence of events:
WM_WINDOWPOSCHANGING
WM_GETMINMAXINFO
WM_NCCALCSIZE
WM_WINDOWPOSCHANGED - IsIconic() is true
WM_MOVE
WM_SIZE - SDL sees minimized state here
When restoring a window, we get this sequence of events:
WM_WINDOWPOSCHANGING
WM_GETMINMAXINFO
WM_NCCALCSIZE
WM_NCPAINT
WM_ERASEBKGND
WM_WINDOWPOSCHANGED - IsIconic() is false
WM_MOVE
WM_SIZE - SDL sees restored state here
On Windows 10 a minimized window has a non-empty client rect, so we were delivering a minimized size before SDL knows that the window is minimized, and then ignoring the restored size when handling the restore message.
The fix is to use IsIconic() which returns the correct window state when WM_WINDOWPOSCHANGED is actually delivered.
If libdecor performs a commit with the frame title being undefined, a crash can occur within the library or its plugins. Always ensure that the title is set to a valid string to avoid this.
This prevents crashes when calling SDL joystick API functions from a different thread while disconnection is happening.
See https://github.com/libsdl-org/SDL/issues/6063 for a more thorough review of joystick locking.
Eliminate excessive calls to SetFullscreen by removing the calls in the libdecor and xdg-toplevel config callbacks.
These calls were being made there in case something explicitly called the window minimization function from within SDL, which unsets fullscreen, and as minimizing a window in Wayland is just a suggestion to the compositor and doesn't actually change the window state or communicate anything back to the application, it was necessary to call SetFullscreen in every call to the config functions just in case something minimized a window via SDL_MinimizeWindow() and later needed to restore it. GNOME in particular had issues when fullscreen set/unset operations were being hammered, leading to overlapping acks and commits when switching to fullscreen.
With the new video system flag to disable unsetting fullscreen when minimizing a window, these calls in the configuration functions are no longer needed and can be removed. This significantly reduces calls to the SetFullscreen() function, reverts #6044 while fixing the issue, and fixes a similar problem when hiding and showing a window initially created with fullscreen flags.
Add quirk flags to the video device struct and add flags to allow video backend drivers to disable mode switching and disable unsetting the fullscreen mode when minimizing a window. As certain platforms can have multiple video backends compiled in at once, #ifdefs, as used by other platforms, aren't suitable as different backends on the same platform may not need the same quirks.
This replaces the formerly dedicated 'disable_display_mode_switching' boolean as additional quirks are needed by the Wayland backend. Helper functions have also been added to simplify reading the flag states.
If the D-Bus subsystem is shutdown and restarted mid-execution, the cached connection will be invalid. Fetch it each time that it is used to ensure that the connection is always from the current context.
