ms_crtc_msc_to_kernel_msc attempts to work around kernel
inconsistencies in reporting msc values by comparing the expected
value with the reported value. If the kernel fails to
actually provide its current values, then just skip the work around
steps as there's really nothing better we can do.

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

If a device is not primary, the PCI device match fails because the
xf86-video-modesetting driver looks specifically for a PCI class match of
0x30000 with a mask of 0xffffff. This fails to match, for example, a
non-primary Intel VGA device, because it is reported as having a class of
0x38000.
Fix that by ignoring the low 16 bits of the class in the pci_id_match table.

A fixed-mode output device like a panel will often only inform of its
preferred mode through its EDID. However, the driver will adjust user
specified modes for display through use of a panel-fitter allowing
greater flexibility in upscaling. This is often used by games to set a
low resolution for performance and use the panel fitter to fill the
screen.
v2: Use the presence of the 'scaling mode' connector property as an
indication that a panel fitter is attached to that pipe.

So the kernel removes the device, and the driver processes the first
