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

modesetting: Implement page flipping support for Present.
Based on code by Keith Packard, Eric Anholt, and Jason Ekstrand.
v2:
- Fix double free and flip_count underrun (caught by Mario Kleiner).
- Don't leak flip_vblank_event on the error_out path (Mario).
- Use the updated ms_flush_drm_events API (Mario, Ken).
v3: Hack around DPMS shenanigans. If all monitors are DPMS off, then
there is no active framebuffer; attempting to pageflip will hit the
error_undo paths, causing us to drmModeRmFB with no framebuffer,
which confuses the kernel into doing full modesets and generally
breaks things. To avoid this, make ms_present_check_flip check that
some CRTCs are enabled and DPMS on. This is an ugly hack that would
get better with atomic modesetting, or some core Present work.
v4:
- Don't do pageflipping if CRTCs are rotated (caught by Jason Ekstrand).
- Make pageflipping optional (Option "PageFlip" in xorg.conf.d), but
enabled by default.
v5: Initialize num_crtcs_on to 0 (caught by Michel Dänzer).
[airlied: took over]
v6: merge async flip support from Mario Kleiner
free sequence after failed vblank queue
handle unflip while DPMS'ed off (Michel)
move flip tracking into its own structure, and
fix up reference counting issues, and add comments.
