Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

x11/wayland: fix screensaver suspension via D-Bus b08b1bde introduced a subtle bug. Despite not using D-Bus types directly, the code used the SDL_USE_LIBDBUS definition set by SDL_dbus.h to conditionally compile calls SDL_DBus_ScreensaverTickle() and SDL_DBus_ScreensaverInhibit(). As a result, it still compiled without SDL_dbus.h included, but screensaver suspension silently failed to work. The D-Bus stuff could probably use some tweaks to be harder to accidentally break, but for now just restore the header includes.

Modifies WaitEvent and WaitEventTimeout to actually wait instead of polling When possible use native os functions to make a blocking call waiting for an incoming event. Previous behavior was to continuously poll the event queue with a small delay between each poll. The blocking call uses a new optional video driver event, WaitEventTimeout, if available. It is called only if an window already shown is available. If present the window is designated using the variable wakeup_window to receive a wakeup event if needed. The WaitEventTimeout function accept a timeout parameter. If positive the call will wait for an event or return if the timeout expired without any event. If the timeout is zero it will implement a polling behavior. If the timeout is negative the function will block indefinetely waiting for an event. To let the main thread sees events sent form a different thread a "wake-up" signal is sent to the main thread if the main thread is in a blocking state. The wake-up event is sent to the designated wakeup_window if present. The wake-up event is sent only if the PushEvent call is coming from a different thread. Before sending the wake-up event the ID of the thread making the blocking call is saved using the variable blocking_thread_id and it is compared to the current thread's id to decide if the wake-up event should be sent. Two new optional video device methods are introduced: WaitEventTimeout SendWakeupEvent in addition the mutex wakeup_lock which is defined and initialized but only for the drivers supporting the methods above. If the methods are not present the system behaves as previously performing a periodic polling of the events queue. The blocking call is disabled if a joystick or sensor is detected and falls back to previous behavior.

video: Add SDL_SetWindowMouseRect. This API and implementation comes from the Unreal Engine branch of SDL, which originally called this "SDL_ConfineCursor". Some minor cleanup and changes for consistency with the rest of SDL_video, but there are two major changes: 1. The coordinate system has been changed so that `rect` is _window_ relative and not _screen_ relative, making it easier to implement without having global access to the display. 2. The UE version unset all rects when passing `NULL` as a parameter for `window`, this has been removed as it was an unused feature anyhow. Currently this is only implemented for X, but can be supported on Wayland and Windows at minimum too.
