Implement the get_release request of the zwp_surface_synchronization_v1
interface.
This commit implements the zwp_buffer_release_v1 interface. It supports
the zwp_buffer_release_v1.fenced_release event for surfaces rendered by
the GL renderer, and the zwp_buffer_release_v1.immediate_release event
for other cases.
Note that the immediate_release event is safe to be used for surface
buffers used as planes in the DRM backend, since the backend releases
them only after the next page flip that doesn't use the buffers has
finished.
Changes in v7:
- Remove "partial" from commit title and description.
- Fix inverted check when clearing used_in_output_repaint flag.
Changes in v5:
- Use the new, generic explicit sync server error reporting function.
- Introduce and use weston_buffer_release_move.
- Introduce internally and use weston_buffer_release_destroy.
Changes in v4:
- Support the zwp_buffer_release_v1.fenced_release event.
- Support release fences in the GL renderer.
- Assert that pending state buffer_release is always NULL after a
commit.
- Simplify weston_buffer_release_reference.
- Move removal of destroy listener before resource destruction to
avoid concerns about use-after-free in
weston_buffer_release_reference
- Rename weston_buffer_release_reference.busy_count to ref_count.
- Add documentation for weston_buffer_release and ..._reference.
Changes in v3:
- Raise NO_BUFFER for get_release if no buffer has been committed,
don't raise UNSUPPORTED_BUFFER for non-dmabuf buffers,
so get_release works for all valid buffers.
- Destroy the buffer_release object after sending an event.
- Track lifetime of buffer_release objects per commit, independently
of any buffers.
- Use updated protocol interface names.
- Use correct format specifier for resource ids.
Changes in v2:
- Raise UNSUPPORTED_BUFFER at commit if client has requested a
buffer_release, but the committed buffer is not a valid linux_dmabuf.
- Remove tests that are not viable anymore due to our inability to
create dmabuf buffers and fences in a unit-test environment.

Implement the set_acquire_fence request of the
zwp_surface_synchronization_v1 interface.
The implementation uses the acquire fence in two ways:
1. If the associated buffer is used as GL render source, an
EGLSyncKHR is created from the fence and used to synchronize
access.
2. If the associated buffer is used as a plane framebuffer,
the acquire fence is treated as an in-fence for the atomic
commit operation. If in-fences are not supported and the buffer
has an acquire fence, we don't consider it for plane placement.
If the used compositor/renderer doesn't support explicit
synchronization, we don't advertise the protocol at all. Currently only
the DRM and X11 backends when using the GL renderer advertise the
protocol for production use.
Issues for discussion
---------------------
a. Currently, a server-side wait of EGLSyncKHR is performed before
using the EGLImage/texture during rendering. Unfortunately, it's not clear
from the specs whether this is generally safe to do, or we need to
sync before glEGLImageTargetTexture2DOES. The exception is
TEXTURE_EXTERNAL_OES where the spec mentions it's enough to sync
and then glBindTexture for any changes to take effect.
Changes in v5:
- Meson support.
- Make explicit sync server error reporting more generic, supporting
all explicit sync related interfaces not just
wp_linux_surface_synchronization.
- Fix typo in warning for missing EGL_KHR_wait_sync extension.
- Support minor version 2 of the explicit sync protocol (i.e., support
fences for opaque EGL buffers).
Changes in v4:
- Introduce and use fd_clear and and fd_move helpers.
- Don't check for a valid buffer when updating surface acquire fence fd
from state.
- Assert that pending state acquire fence fd is always clear
after a commit.
- Clarify that WESTON_CAP_EXPLICIT_SYNC applies to just the
renderer.
- Check for EGL_KHR_wait_sync before using eglWaitSyncKHR.
- Dup the acquire fence before passing to EGL.
Changes in v3:
- Keep acquire_fence_fd in surface instead of buffer.
- Clarify that WESTON_CAP_EXPLICIT_SYNC applies to both backend and
renderer.
- Move comment about non-ownership of in_fence_fd to struct
drm_plane_state definition.
- Assert that we don't try to use planes with in-fences when using the
legacy KMS API.
- Remove unnecessary info from wayland error messages.
- Handle acquire fence for subsurface commits.
- Guard against self-update in fd_update.
- Disconnect the client if acquire fence EGLSyncKHR creation or wait
fails.
- Use updated protocol interface names.
- User correct format specifier for resource ids.
- Advertise protocol for X11 backend with GL renderer.
Changes in v2:
- Remove sync file wait fallbacks.
- Raise UNSUPPORTED_BUFFER error at commit if we have an acquire
fence, but the committed buffer is not a valid linux_dmabuf.
- Don't put buffers with in-fences on planes that don't support
in-fences.
- Don't advertise explicit sync protocol if backend does not
support explicit sync.

Not having swap_buffers_with_damage could cause a performance impact on
some backends, but at least on GBM it causes no issues. It also seems to
confuse users into thinking it's a legitimate error which could explain
session slowness.
Similarly with buffer_age, whilst we do lose a little bit of performance
by not being able to do partial renders, it is not a great deal, and the
user is unlikely to be able to do anything about it in any event.
Remove the warning; we print the full extension list at startup, so we
already have enough information from the logs to easily diagnose any
real errors.

EGL_IMG_context_priority allows the client to request that their
rendering be considered high priority. For ourselves, this is important
as we are interactive and any delay in our rendering causes input-output
jitter; a less than smooth user interactive. So if the driver supports
setting the context priority, try and create our EGLContext as high
priority. The driver may reject our request due to system restrictions,
in which case it will fallback to normal priority, but if successful it
will reschedule our rendering and all of its dependencies to execute
earlier, especially important when the GPU is being hogged by background
clients.

zwp_linux_dmabuf_v1 allows clients to pass an explicit pitch for each
plane, but wl_shm only takes a single pitch parameter; the pitch for
secondary planes must be inferred.
Multi-plane sub-sampled textures have partial width/height, e.g.
YUV420/I420 has a full-size Y plane, followed by a half-width/height U
plane, and a half-width/height V plane.
GStreamer's waylandsink - the only user of wl_shm YUV formats - expects
the implementation to follow the example of Xv and implicitly divide the
pitch for secondary planes by the subsampling factor. gl-renderer was
not doing this, and instead just using the (larger) stride provided by
the client for all planes in the buffer.
Fix gl-renderer to divide pitch by the subsampling factor when uploading
from subsampled SHM buffers into GL textures, also dividing co-ordinates
when doing offset partial uploads.

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).
