This removes the dependency on DEMUXER_TYPE_* and the file_format parameter from the stream open functions. Remove some of the playlist handling code. It looks like this was needed only for loading linked mov files with demux_mov (which was removed long ago). Delete a minor bit of dead network-related code from stream.c as well.
