We change the video info base on the received buffer. We need to
rollback these changes whenever we want to copy into our internal
pool of buffers.
https://bugzilla.gnome.org/show_bug.cgi?id=790057
The SHM interface does not allow passing arbitrary strides and offsets,
for this reason, we simply disable this feature from the proposed pool.
This fixes video artifact seen when using the FFMPEG based video
decoder.

When the sink receives a buffer that is neither a wl_shm one nor a
dmabuf one, this buffer is copied to an internal wl_shm buffer before
being sent to the display.
In that case, the actual size of the received buffer (which may differ
from the one negotiated in the caps) must be used.

Unless the video format has an alpha component (ARGB, ...), set the
video_surface opaque.
In the usual case where the black area_surface has the same size as the
video_surface (eg: run gst-play-1.0 video.mp4), this makes the black
surface totally occluded which makes weston compositor's life easier
since it can ignore that surface.
Also unconditionally set the black area_surface opaque.

Reset redraw_pending at display disconnection, so we can re-connect
later from a clean state (avoid endless buffer drops).
Add a log to inform of dropped buffers.

Support the wayland zwp_linux_dmabuf_unstable_v1 protocol.
SHM formats and DMABuf formats are exposed differently in caps: the
DMABuf formats are flagged with GST_CAPS_FEATURE_MEMORY_DMABUF.
No buffer pool is proposed for DMABuf buffers, it is the upstream
element responsibility to provide with such buffers.

This is specific to when the waylandsink is not being embedded. In
this patch we pass the render lock to the window so it can safely
call gst_wl_window_set_render_rectangle() with the new size.
https://bugzilla.gnome.org/show_bug.cgi?id=722343
We already take the render lock from the wlqueue thread in some other
place which indicates that there is no use of this atomic instead of
a proper locking mechanism.
When we don't have a viewporter (scaling support), we can't use the
1x1 scaleup image trick. Instead, we need to allocate a buffer with
the same size as the area that need to have black background.
This add support for non-standard strides to be used. Note that
some extra work is needed for multi-plane format which may have
a different GstMemory object per plane. This is not currently a
problem since SHM interface is limited to 1 memory.
The buffer pool API does not allow multiple of owner. This otherwise
lead to error when renegotiation take place. Aso consider the
allocation query "need_pool" boolean.
This makes the viewporter interface optional. The end result is
obviously far from optimal, though it greatly helps testing on older
compostitors or gnome-wayland. We can make it strictly needed later when
this new interface get widely adopted.

Waylandsink needs exception code in gst_wayland_sink_set_window_handle().
After making sink->window, User can call
gst_wayland_sink_set_window_handle(). It is the user's fault, but
Waylandsink needs to handle the exception, if not then sink->window is
changed and rendering fails.
https://bugzilla.gnome.org/show_bug.cgi?id=747482
Waylandsink needs exception code in gst_wayland_sink_set_context(). After
calling gst_wayland_sink_set_context(), below code is set.
GST_ELEMENT_CLASS (parent_class)->set_context (element, context); but, If
user can call onemore. It is user's fault. but waylandsink need to
exception.

This wl_display proxy is temporary only until waylandsink goes NULL,
at which point the connection to the display is disposed. Unfortunately,
if this is advertised as a GstContext, playbin will cache it and re-feed
it to the sink when it goes PLAYING again, but the wl_display pointer
will at that point be invalid and cause a crash.
Another solution to the problem would be to also cache the GstWlDisplay
object inside the GstContext, which would automatically ref-count
the display connection, but I see no reason in doing that at the moment,
as there are no known users of this GstContext outside waylandsink.
It's probably better to avoid chasing hidden refcounts.
