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.
