Patch to the hal spec

The Sansa Fuze mp3 player stores playlists in the m3u format, but with
two quirks:

1) playlists must use dos format (i.e <cr><lf> line endings and
   \ pathname separators)
2) The entries in the playlist must be relative paths starting
   at the playlist file. Absolute paths are not supported by the
   current version of the firmware. 

The patch defines two new hal quirks:
portable_audio_player.quirk.playlist_dos_encoded
and
portable_audio_player.quirk.use_relative_paths

I am attaching a patch to the hal spec, and also to 
another patch to the fdi file in order to enable these for the
Sansa Fuze. 

There is also a corresponding patch to rhythmbox which allows 
it to write playlists on these devices.
