Jeff Hostetler 4875c9791e list-objects-filter-options: support --no-filter
Teach opt_parse_list_objects_filter() to take --no-filter
option and to free the contents of struct filter_options.
This command line argument will be automatically inherited
by commands using OPT_PARSE_LIST_OBJECTS_FILTER(); this
includes pack-objects.
