modesetting: Add support for DRI2 with glamor.
This is derived from the intel driver DRI2 code, with swapchain and
pageflipping dropped, functions renamed, and vblank event management
shared code moved to a vblank.c for reuse by Present.
This allows AIGLX to load, which means that you get appropriate
visuals exposed in GL, along with many extensions under
direct-rendering that require presence in GLX (which aren't supported
in glxdriswrast.c).
v2: Drop unused header includes in pageflip.c, wrap in #ifdef GLAMOR.
Drop triple-buffering, which was totally broken in practice (I'll
try to fix this later). Fix up some style nits. Document the
general flow of pageflipping and why, rename the DRI2 frame event
type enums to reflect what they're for, and handle them in a
single switch statement so you can understand the state machine
more easily.
v3: Drop pageflipping entirely -- it's unstable on my Intel laptop
(not that the normal 2D driver is stable with pageflipping for
me), and I won't get it fixed before the merge window. It now
passes all of the OML_sync_control tests from Jamey and Theo
(except for occasional warns in timing -fullscreen -divisor 2).
v4: Fix doxygen at the top of vblank.c
