Move mark_atom_in_object_info() from cat-file to ref-filter and
start using it in verify_ref_format().
It also means that we start reusing verify_ref_format() in cat-file.
Start from simple moving of mark_atom_in_object_info(),
it would be removed later by integrating all needed processes into
ref-filter logic.
