Eliminate filename length restrictions, remote ofmt->filename()

Get rid of remaining dependencies on FILENAME_MAX, which ought to have
been removed a long time ago.

Remove ofmt->filename(); all implementations pretty much do the same
thing and there is absolutely no reason to duplicate that
functionality all over the place.
