24267	Simplify Query.build_filter()	Anssi Kääriäinen	Simon Charette	"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."	Cleanup/optimization	assigned	Database layer (models, ORM)	dev	Normal				Accepted	0	0	0	0	0	0
