Prevents a failure from being ignored.
This provides an API wrapper around the kernel interface for queueing
a vblank event, simplifying all of the callers.
v2: Fix missing '|' in computing vbl.request.type
v3: Remove spurious bit of next patch (thanks, Michel Dänzer)

The glamor_egl module that the GLAMOR paths are using is only built if
GLAMOR_HAS_GBM is true, and there's no plan for implementing the
module without GBM. Simplify modesetting's code as a result.

The "if (pixmap) ..." block this commit removes is inside an
"if (pixmap == NULL) ..." block, so it will never execute.

glamor_name_from_pixmap and glamor_fd_from_pixmap return CARD16 and
CARD32 values via pointers. The current code uses uint16_t and
uint32_t which will probably be the same but it's safer to use the
datatypes as specified by the function.

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
