Add a parser for metadata

Original commit message from CVS:
Add a parser for metadata
(demux_metadata): Given the buffer containing the metadata, look through it and
get the info out of it.
(wav_new_chunk_callback): Change the if statement to a switch statement.
Handle GST_RIFF_TAG_LIST by changing what the type of list it is and parsing out
metadata if it is "INFO".
