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: Remove DRM_CRTC_SEQUENCE_FIRST_PIXEL_OUT flag. This has
been removed from the proposed kernel API.
Add NULL parameter to drmCrtcQueueSequence ioctl as we
don't care what sequence the event was actually queued to.
v3: Adapt to pthread clock switch to MONOTONIC
v4: Fix scope for wsi_display_mode andwsi_display_connector allocs
Suggested-by: Jason Ekstrand <jason@jlekstrand.net>
v5: Adopt Jason Ekstrand's coding conventions
Declare variables at first use, eliminate extra whitespace between
types and names. Wrap lines to 80 columns.
Use wsi_rel_to_abs_time helper function to convert relative
timeouts to absolute timeouts without causing overflow.
Suggested-by: Jason Ekstrand <jason.ekstrand@intel.com>
v6:
Change WSI fence wait function to return VkResult instead of
bool. This makes the meaning of the return value easier to
understand, and allows for the indication of failure.
Also change the WSI fence wait function to take only absolute
timeouts and not provide an option for a relative timeout. No
users wanted relative timeouts, and it's simpler if that option
isn't available.
Terminate the DPMS property loop once we've found the property.
Assert that the fence hasn't already been destroyed in
wsi_display_fence_destroy.
Rearrange the event handler function order in the file to place
routines in an easier to find order.

v7:
Adapt to API changes for surface_get_capabilities
v8:
Use wsi->alloc in register_display_event so that callers
don't have to dig out an allocator for us.
v9:
Fix a few minor formatting issues
Suggested-by: Jason Ekstrand <jason.ekstrand@intel.com>
v10:
Use wsi->alloc if none provided in wsi_display_fence_alloc.
Now that drivers are expected to pass the allocator argument
straight through from the application, we need to check those
for NULL everywhere.
