(show_all_fs):

(show_all_fs):
Revert to boolean value; the old negative value is
now in show_local_fs.
(show_local_fs): New variable.
(show_dev): New args me_dummy and me_class.  Use show_local_fs
and boolean show_all_fs in combination with these new args
to decide whether to show a device.
(show_disk): Pass flags to show_dev.
(show_point): Use a non-dummy mount entry if possible.
(show_all_entries): Pass flags to show_dev.
(main): --local sets show_local_fs now.  Ask for file system types if
show_local_fs is nonzero, since ME_REMOTE might need them.
