Adds an audio source and audio capsfilter/queue/convert, creating
a new branch on camerabin2 that is used to feed encodebin with
audio buffers for video recording.
Adds properties to check what caps are supported on the
viewfinder (from the camerasrc viewfinder pad) and another
one to set a caps for the viewfinder.
Use video_renegotiate and image_renegotiate booleans to make
the videosrc negotiate the capture caps on the first capture because
the caps might be set before wrappercamerabinsrc goes into PLAYING
and pads drop the internal renegotiate event.
This is required as the output-selector is using the 'none' negotiation
mode.
When setting the internal capsfilter caps for capture we should put
the full caps instead of trying to fixate it ourselves. This way we let
the elements (and mostly the source) select the best format instead
of defaulting to what the pad fixation function picks.
This element analyses video buffers to identify if they are progressive,
interlaced or telecined and outputs buffers with appropriate flags for a
downstream element (which will be the deinterlace element, after some
forthcoming modifications) to be able to output progressive frames and
adjust timestamps resulting in a progressive stream.
Remove bogus freeing of pad element_private data that we
never set (collectpads uses it, which causes confusion here).
Also, check that our collectpads instance exists before using
it. Partial fix for #636011.

Fixes#641047.
If videobin/imagebin was never set to READY state the ownership
of elements created and set by application were never taken by
bin and therefore gst_object_sink is called for these elements
before unreffing (they may still be in floating state and not
unreffed properly without sinking first)
Even if VBR headers are missing, we can't guarantee that a stream is in
fact a CBR stream, so it's safer to let baseparse calculate the average
bitrate rather than assume a CBR stream. However, in order to make
/some/ metadata available before the requisite number of frames have
been parsed, this posts the bitrate from the non-VBR headers as the
nominal bitrate.
