dcaparse: Expose frame size in caps
...
This exports the size of the frame (number of bytes from one sync point
to the next) as the "frame_size" field in caps.

depth and this allows better negotiation.

baseparse: tune QUERY_SEEKING response

Even if we currently do not have a duration yet, assume seekable if
it looks like we'll likely be able to determine it later on
(which coincides with needed information to perform seeking).

mpegaudioparse: Post CBR bitrate as nominal bitrate
...
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.

Don't unref the event if it hasn't been handled, because the caller
