Continue removing die() calls from ref-filter formatting logic,
so that it could be used by other commands.
Change the signature of parse_ref_filter_atom() by adding
strbuf parameter for error message.
The function returns the position in the used_atom[] array
(as before) for the given atom, or -1 to signal an error.
Upon failure, error message is appended to the strbuf.
