[PATCH v10 10/20] ref-filter: introduce refname_atom_parser_internal()

From: Karthik Nayak <redacted>
Since there are multiple atoms which print refs ('%(refname)',
'%(symref)', '%(push)', '%(upstream)'), it makes sense to have a common
ground for parsing them. This would allow us to share implementations of
the atom modifiers between these atoms.
Introduce refname_atom_parser_internal() to act as a common parsing
function for ref printing atoms. This would eventually be used to
introduce refname_atom_parser() and symref_atom_parser() and also be
internally used in remote_ref_atom_parser().
