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.

We've supported indirect rendering pbuffers for a while, but not direct
rendering pbuffers. The way we do this is by creating a hidden pixmap
and wrap that in a GLX pbuffer. This only works when we have DRI2 on
the server, but if the server doesn't have DRI2, it won't expose configs
with pbuffer bits enabled.
