for-each-ref: rename some functions and make them public
Rename some of the functions and make them publicly available. This is a preparatory step for moving code from 'for-each-ref' to 'ref-filter' to make meaningful, targeted services available to other commands via public APIs. Functions renamed are: parse_atom() -> parse_ref_filter_atom() verify_format() -> verify_ref_format() get_value() -> get_ref_atom_value() grab_single_ref() -> ref_filter_handler() sort_refs() -> ref_array_sort() show_ref() -> show_ref_array_item() default_sort() -> ref_default_sorting() opt_parse_sort() -> parse_opt_ref_sorting() cmp_ref_sort() -> cmp_ref_sorting() Rename 'struct ref_sort' to 'struct ref_sorting' in this context.
