From: Karthik Nayak <karthik.188@xxxxxxxxx>
Add a function called 'for_each_reftype_fullpath()' to refs.{c,h}
which iterates through each ref for the given path without trimming
the path and also accounting for broken refs, if mentioned.
Add 'filter_ref_kind()' in ref-filter.c to check the kind of ref being
handled and return the kind to 'ref_filter_handler()', where we
discard refs which we do not need and assign the kind to needed refs.
