The code seems to use `continue` and `break` as if both refer to the
surrounding `while` loop. But because `break` breaks out of the
`switch`, they actually have the same effect.
This may have caused the loop not to terminate when it should. E.g. when
`skip_backwards_streams` drops a buffer we should abort the aggregation
and wait for all pads to be filled again. Instead, we might have just
selected a subsequent pad as our new "best".
Replace `break` with `done = TRUE; break`, and `continue` with `break`.
Then simplify the code a bit.

gst_v4l2_open() is called by gst_v4l2_device_provider_probe_device(),
where the GstV4l2Object is created without an associated GstElement.
If gst_v4l2_open() fails, it raises a bus message, but without an
element, a precondition check fails on
gst_element_message_full_with_details() generating a crash if running
with fatal-warnings debug mode.
GstV4l2Error is a helper to raise error bus messages when it is
appropiated. This patch changes the direct bus messages to this
helper, and the elements will actually send the error message.

When we are dropping a buffer in find_best_pad (e.g. waiting for a
keyframe, or skipping backwards timestamp), return
GST_AGGREGATOR_FLOW_NEED_DATA to make sure we have enough data at the
next run. Otherwise, a stream that accidentally fell behind (e.g.
relinking race, or just waiting for a keyframe) will never get the
opportunity to catch up to the other one, because the other one will
always keep advancing.

With Qt 5.15 multiple qmlgloverlay elements would produce:
ASSERT: "!m_gl->property(QSG_RENDERCONTEXT_PROPERTY).isValid()" in file /path/to/qt5/qtdeclarative/src/quick/scenegraph/qsgdefaultrendercontext.cpp, line 121
Workaround by setting the (seeminigly unused) property before
initialization.

* Trying to disconnect a stream from a running splitmuxsink by flushing
it results in the FLUSH_START blocking in the stream queue's
gst_pad_pause_task because the flush did not unblock
complete_or_wait_on_out, so add a check for ctx->flushing there.
* Add a GST_SPLITMUX_BROADCAST_INPUT so check_completed_gop notices
flushing changed and the incoming push is unblocked.
* Pass the FLUSH_STOP along to the muxer without waiting.

GCC 10 was complaining like following. It really is complaining about default cases returning
with potentially unitialized *desval, but those cases in the switch should never be hit.

We claim output buffers are nal-aligned, but that wasn't
actually true: We would push out a partial nal in case
the nal doesn't fit into the max encoder-selected output
buffer size, and then the next buffer would not start
with a sync marker. That's not right and makes h264parse
unhappy.
Instead accumulate buffers until we have a full frame
(we can't rely on the NAL_END flag, it's always set).

Make extra sure all the required mmal libs such as libmmal_vc_client.so
actually get linked and stay linked. Otherwise the above error happens
it seems.

This identifiers are registered in the MPEG-RA and defined
to be used by the Dolby Vision AVC/HEVC streams.
This is a first step to present the stream to the decoder.
Additional box parsing of DOVIConfigurationBox is necessary
to complete the media presentation with proper Dolby Vision
enhancements.
