The uvcsink was limited to only transfer YUY2 and MJPEG. For the
uncompressed formats there is no technical reason not to support them.
Since gst_video_format_to_string is already supporting more fourcc than
only YUY2 we use the default path in gst_v4l2uvc_fourcc_to_bare_struct
to create structures for more formats and bail out if the returned
format is not from the uncompressed type.

A zero-sized box is not really a problem and can be skipped to look at any
possibly following ones.
BMD ATEM devices specifically write a zero-sized bmdc box in the sample
description, followed by the avcC box in case of h264. Previously the avcC box
would simply not be read at all and the file would be unplayable.

This notably follow the way we order the template and keeps the
format:Interlaced caps at the end. This change also fixes
an early skip check, that would skip if a driver only supports
alternate interlacing for a specific format. It also fixes
a bug where only the last resolution of a discrete frame size
was allowed to use format:Interlaced. Finally, similar to template
caps code, simplify the caps for earch featurs, making the debug output
manageable and (marginally) improve negotiation speed.
This change will make it easier to introduce memory:DMABuf.

In qml6glsrc, we capture the application by copying the back buffer into
our own FBO. The afterRendering() signal is too soon as from the apitrace, the
application has been rendered into a QT internal buffer, to be used as a cache
for refresh.
Use afterFrameEnd() signal instead. This works with no delay on GLES. With GL
it seems to reduce from 2 to 1 frame delay (this may be platform specific). A
different recording technique would need to be used to completely remove this
delay.

In fact, the va decoder is just a internal helper class and its access
is under the control of all dec elements. So far, there is no parallel
operation on it now.
At the other side, some code scan tools report race condition issues.
For example, the "context" field is just protected with lock at _open()
but is not protected at _add_param_buffer().
So we just delete all its lock usage.

Timestamps are untouched by default, but the new mode can now be enabled to replace RTP timestamps
with ones generated from the buffer PTS. Making it an enum in case different modes are needed in the future.
That allows for a rtpjitterbuffer to do proper drift compensation, so that the stream coming out of gst-rtsp-server
is not drifting compared to the pipeline clock and also not compared to the RTCP NTP times.
Most of the code is borrowed from rtpbasepayload, as it's exactly its behaviour which I wanted to bring here.

Be smarter when allocating sink and source memory pools to reduce the
memory footprint. Use gst_v4l2_decoder_get_render_delay() to know the
need number of buffers for downstream element.
Handle errors in case of memory allocation failures.
