Now that the old way of building lookups isn't supported any more, we
could restructure build_filter(). Steps included:
- Remove related field's get_lookup_constraint(), instead write proper
lookups for relational fields, too.
- Do not use lookup_name in build_filter(), instead use Lookup flags
where needed.
- Ultimate goal could be usage of resolve_ref() in build_filter()
instead of direct use of setup_joins(). In this case build_filter() would
be simplified a lot. It is uncertain if this goal is achievable.
