Peter Hutterer 421f5dfdd8 DRI2: Don't return junk reply instead of blocking in glXWaitForSbcOML() 
DRI2WaitSBC() didn't block if requested targetSBC wasn't yet reached.

Instead it returned a xreply with uninitialized junk return values, then
blocked the connection until targetSBC was reached.

Therefore the client didn't block, but continued with bogus return
values from glXWaitForSbcOML.

This patch fixes the problem by implementing DRI2WaitSBC similar
to the clean and proven DRI2WaitMSC implementation.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
following article:
