xlib: Make display a cairo_device_t
The code now uses the locking of the cairo_device_t instead of its own mutexes. The code was modified so that cairo_surface_t does no longer reference the display directly. Instead, it calls _cairo_xlib_display_acquire(). If a function assumes an already acquired display, it now requires the caller to provide a cairo_xlib_display_t parameter. Functions that do not require an acquired display will not require the display parameter or they will take the cairo_device_t instead.
