Description
During caps negotiation, we currently don't receive events, so we don't know the details of the audio/video format.
Ideas:- Start the listener earlier so we can look at events and "autodetect" the audio/video format
- Add a tiny RPC interface to the streaming sources that allows retrieving the audio/video format
Further thought:
Independent of this issue maybe we should introduce .rst.AudioFormat and .rst.VideoFormat as toplevel data definitions in RST and use these in .rst.ImageMessage and .rst.SoundMessage)

- src/gst_rsb_src_base.{h,cpp}: added
gst_rsb_src_base_ensure_listener, gst_rsb_src_base_ensure_format,
gst_rsb_src_base_set_format; these are used to obtain format
information from initial event and store it in the element - src/gst_rsb_audio_src.{h,cpp}: added gst_rsb_audio_src_set_format
which extracts format information from an rst::audition::SoundChunk
object - src/gst_rsb_video_src.{h,cpp}: similar gst_rsb_video_src_set_format
