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.
