gstwaylandsink: Add support for the "render-rectangle" property

We already implement the `set_render_rectangle` videooverlay interface,
thus install the videooverlay property accordingly.

gstwayland: Move reusable parts of the waylandsink into a library

In preparation for the new element `GstGtkWaylandSink`, move reusable
parts out of `GstWaylandSink` into the already exisiting but very
barebone library.

Notable changes include:
 - the `GstWaylandVideo` interface was dropped
 - support for `wl-shell` was dropped
 - lots of renaming in order to match established naming patterns
 - lots of code modernisations, reducing boilerplate
 - members were made private wherever possible

amfencoder: always empty the queue when pushing output samples

queueing up in AMFComponent whenever QueryOutput() returns AMF_REPEAT
(and do_wait is FALSE). This has negative impact on latency when the

d3d11screencapture: Fix missing/outdated cursor shape

d3d11screencapture can miss a cursor shape to draw or draw an outdated cursor shape.
 - AcquireNextFrame only provides cursor shape when there is one update
 - current d3d11screencapture skips cursor shape when mouse is not drawn

So, if a gstreamer application uses d3d11screencapture with cursor initially not drawn
"show-cursor"=false and then switches this property to true, the cursor will not be
actually drawn until AcquireNextFrame provides a new cursor shape.
This commit makes d3d11screencapture always update the cursor shape information, even
if the mouse is not drawn. d3d11screencapture will always have the latest cursor shape
when requested to draw it.

whenever it is not possible to share our buffers. This typically happen
when downstream does not support GstVideoMeta.

Not handling this would cause the decoder thread to exit silently and the
pipeline to stall.

webrtcbin: reuese the same fec/rtx/red payload types for the same media payload

WHen bundling, if multiple medias are used with the same media payload, then
each of the fec/rtx/red additions would add a distinct payload.  This could
very easily overflow the available payload space.

Instead, track the relationship between the media payload value and
the relevant fec/rtx/red payload values and reuse them whenever
necessary, even when bundling.

e.g.

...
a=group:BUNDLE video0 video1
m=video 9 UDP/SAVPF 96 97
a=mid:video0
a=rtpmap:96 VP8/90000
a=rtpmap:97 rtx/90000
a=fmtp:97 apt=96
...
m=video 9 UDP/SAVPF 96 97

a=rtpmap:96 VP8/90000
a=rtpmap:97 rtx/90000

d3d11device: Enhance format enumeration and debugging

* Enhance debug log to print human readable D3D11_FORMAT_SUPPORT flags
  value, instead of packed numeric flagset value.
* Only device supported format will be added to format table.
  Depending on device feature level (i.e., D3D9 feature devices),
  16bits formats will not be supported. Although there might be formats
  we deinfed but not supported, it will not be a major issue in practice
  since our D3D11 implementation does not support legacy devices already
  (known limitation) and also old d3dvideosink will be promoted in that case.
