Fix track formatting problems in playlist.c

Some changes in behavior were made with filesystem code commit
for the sake of compatibility that changed expected behavior.

* Restore substitution of drive spec in fully-qualified DOS paths
with the playlists's volume spec (or root on univolume targets).
Drive-relative paths of the form "c:foo" (no separator after
':') will be treated as purely relative.

* Restore old behavior of preserving leading whitespace in the
source path and trimming only trailing tabs and spaces.

* Multivolume: Volume substition on fully-qualified UNIX/RB paths
has NOT been reintroduced (and perhaps wasn't intended in the
first place). They will not be modified because there is no
ambiguity to resolve. Doing so would prevent a playlist on
external storage from referencing a file on main storage without
qualifying it with "/<0>...".

* Plain relative paths are and always have been interpreted as
relative to the location of the playlist.
