Use EGL fence sync objects to emit timepoints for the beginning and the
end of rendering on the GPU. The timepoints are emitted asynchronously
using the sync file fds associated with the fence sync objects. The sync
file fds are acquired using the facilities provided by the
EGL_ANDROID_native_fence_sync extension.
The asynchronous timepoint submissions are stored in a list in
gl_output_state until they are executed, and any pending submissions
that remain at output destruction time are cleaned up.
If timelining is inactive or the required EGL extensions are not
present, then GPU timepoint processing and emission are skipped.
Note that the GPU timestamps returned by sync files are in the
CLOCK_MONOTONIC clock domain, and are thus compatible with the
timeline timestamps (which also are in the CLOCK_MONOTONIC domain).

The sync file functionality is required by the upcoming GPU render
timeline work, but it's only available in relatively new linux kernel
versions (4.7 and above).
This commit provides a "sanitized" version of the required sync file
definitions. On systems that don't have the sync file header (due to
having an older kernel), we will be able to fall back to our own
definitions when building.

All planes being displayed have a framebuffer. What makes 'fb_plane'
special is that it's being displayed as the primary plane by KMS.
Previous patchsets renamed this to 'primary_plane' to match the KMS
terminology, namely the CRTC's base plane, which is controlled by
drmModeSetCrtc in the legacy API, and identified by PLANE_TYPE ==
"Primary" in the universal-plane API.
However, Weston uses 'primary_plane' internally to refer to the case
where client content is _not_ directly displayed on a plane, but
composited via the renderer, with the result of the compositing then
shown.
Rename to 'scanout_plane' as our least-ambiguous name, and document it a

sprite creation code is useful.
The removal code now actually removes the plane from the list.
In doing this, the gymnastics required to exact the CRTC ID the plane
was last on when making a disabling drmModeSetPlane call have been
removed; specifying the CRTC is not necessary when disabling a plane.

only when manipulating the lists.
