Re: xcb_register_for_special_event, xcb_unregister_for_special_event,
xcb_check_for_special_event, and xcb_wait_for_special_event.

There was some push-back the last time something similar to this came
up, on the theory that it should be in a separate library from xcb[1].
That said, we may have reached the point where it's just too useful to
not have in libxcb.

Does this interface work for the rest of the things needed for GLX?

This hunk doesn't appear to be related to event queue splitting. Should
it be in a separate commit?
