           Summary: [typefinding] certain flac-in-ogg files not detected any

Playback of certain flac-in-ogg files is broken because oggdemux doesn't
recognise them properly any longer. These files aren't framed according to the
ogg mapping spec, but basically just contain the flac bytestream in ogg
packets. These files then have a 4-byte packet as first ogg packet, and we need
to detect the right type from these 4 bytes. The typefinder, however, requires
at least 6 bytes and hence fails to detect the stream properly.

Sample file: samples-mplayer/flac.samples/Yesterday.ogg
