    xwayland: handle global object destruction
    
    Certain global objects, such as outputs, can be destroyed during
    the session. We must handle that and not crash.

    xwayland-shm: don't create alpha buffers if the window doesn't have alpha
    
    If the window is using a 24 bit visual, we must request a buffer
    format without alpha, or garbage is rendered.

    configure: Track updated version of libxtrans
    
    XWayland fails to initialize in some systems complaining about realloc
    problems on libxtrans (when ListenOnOpenFD() is called). It got fixed in
    libxtrans version 1.2.7, more specifically:

    xkb: Add XkbCompileKeymapFromString()
    
    This new function compiles a keymap from an in-memory string.  We use it
    to add a new keyooard device init function,
    InitKeyboardDeviceStructFromString(), which inits a keyboard device with
    a keymap specified as a string instead of a rmlvo set.

    dbe: Cleanup in CloseScreen hook not ext CloseDown
    
    Instead of registering an extension CloseDownProc when adding the dbe
    extension this patch hooks into pScreen->CloseScreen so that the chain
    of pScreen->DestroyWindow hooks remains valid until all windows have
    been destroyed. Previously it was possible for DbeResetProc to be called
    before the root window had been destroyed and the unwrapping of
    pScreen->DestroyWindow would clobber the chain of callbacks.
    
    This is needed for xwayland to be able to know when the root window is
    destroyed so it can unredirect root sub-windows.
