This extension provides fences and frame count information to direct
display contexts. It uses new kernel ioctls to provide 64-bits of
vblank sequence and nanosecond resolution.
v2:
Rework fence integration into the driver so that waiting for
any of a mixture of fence types (wsi, driver or syncobjs)
causes the driver to poll, while a list of just syncobjs or
just driver fences will block. When we get syncobjs for wsi
fences, we'll adapt to use them.
v3: Adopt Jason Ekstrand's coding conventions
Declare variables at first use, eliminate extra whitespace between
types and names. Wrap lines to 80 columns.
