This is mainly a refactor. I'm hoping it will make some things easier in the future due to cleanly separating codec metadata and stream metadata. Also, declare that the "codec" field can not be NULL anymore. demux.c will set it to "" if it's NULL when added. This gets rid of a corner case everything had to handle, but which rarely happened.
