This code is going to be extended to support GBM BOs soon. This small
abstraction removes a lot of direct dumb_bo access, so we can add that
support in one place, rather than putting conditionals at every
pitch/handle/etc access.

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.

When no devicename is found in the option then the driver probes
by PciInfo no matter if it's valid or not. Instead of doing this
use PciInfo only when it's valid and fall back to the devicename
otherwise. With devicename probing use open_hw() to fall back
on the KMSDEVICE environment variable or to the default device.
