[PATCH 2/3] AVRCP: Metadata item #7 should return TrackDuration

Should be total playing time of the track (TrackDuration)
in msec, not current position within track.

track_len is initialized with 0xFFFFFFFF, because as per spec when it
has this value it means it's not available (see media_info_init())


Otherwise seems good.

Actually that's not quite what I meant. The idea was this:

MEDIA_INFO_PLAYING_TIME = 7,
MEDIA_INFO_LAST,

That way you can just keep adding new entries above MEDIA_INFO_LAST and
its value will always be the last "real" value + 1 (which also means
that the comparison in the for-loop changes from <= to <).

+++++ Thanks. As you can tell, C is not my most frequently used language...
I'll take care of it and resubmit.
