    dri2: Track event mask in client code.

    When direct rendering is being used, DRI2 BufferSwapComplete events are
    sent unconditionally to clients, even if they haven't been requested.
    This causes error messages to be printed by every freeglut application
    of the form

      freeglut (./gears): Unknown X event type: 104

    and might confuse other clients.

    This is a fixed up version of the patch by Jesse Barnes, which drops
    BufferSwapComplete events if they are not requested by clients.

    Fixes fdo bug 27962.
