for-each-ref: introduce new structures for better organisation

Browse source 
Introduce 'ref_filter_cbdata' which will hold 'ref_filter'
(conditions to filter the refs on) and 'ref_array' (the array
of ref_array_items). Modify the code to use these new structures.

This is a preparatory patch to eventually move code from 'for-each-ref'
to 'ref-filter' and make it publicly available.
