song: converted typedef Song to struct song

Again, a data type which can be forward-declared.

[ew:
 * used "struct mpd_song" instead to avoid token duplication
   (like I did with "struct mpd_tag") as there's no good
   abbreviation for "song" and identical tokens on the same
   line don't read well
 * rewritten using
     perl -i -p -e 's/\bSong\b/struct mpd_song/g' src/*.[ch]
   since it was too hard to merge
 * also, I don't care much for forward declarations
