Rework the audio caps similar to the video caps. Remove width/depth/endianness/signed fields and replace with a simple string format and media type audio/x-raw. Create a GstAudioInfo and some helper methods to parse caps. Remove duplicate code from the ringbuffer and replace with audio info. Use AudioInfo in the base audio filter class. Port elements to new API.
