DRI2: add support for new DRI2 protocol requests

Browse Source 
Support the new DRI2 2.2 protocol requests: DRI2SwapBuffers, DRI2GetMSC,
DRI2WaitMSC, DRI2WaitSBC and DRI2SwapInterval.

These requests allow the server to support the SGI_video_sync,
SGI_swap_interval, and OML_sync_control GLX extensions if DDX support is
present.  The new DDX APIs are documented in dri2.h.
