681f7e2b13 Fixed #20577 -- Deferred filtering of prefetched related querysets. 
Added internal interface to QuerySet that allows to defer next filter
call till .query is accessed. Used it to optimize prefetch_related().

Thanks Simon Charette for the review.

Subquery expression objects, when pickled, were evaluating the QuerySet
objects saved in its _constructor_args attribute.

8f30556329 Renamed Field.rel attribute to remote_field 
Field.rel is now deprecated. Rel objects have now also remote_field
attribute. This means that self == self.remote_field.remote_field.

In addition, made the Rel objects a bit more like Field objects. Still,
marked ManyToManyFields as null=True.

f95122e541 Fixed #24381 -- removed ForeignObjectRel opts and to_opts 
These cached properies were causing problems with pickling, and in
addition they were confusingly defined: field.rel.model._meta was
not the same as field.rel.opts.

Instead users should use field.rel.related_model._meta inplace of
field.rel.opts, and field.rel.to._meta in place of field.rel.to_opts.

3e4dc5ecf2 Fixed #21853 -- Fixed Manager.__module__ to properly return 'django.db.models.manager'. 
The combination of BaseManager.from_queryset() and RenameMethodsBase results in
Manager.__module__ having the wrong value. This can be an issue when trying to
pickle the Manager class.

31fadc1202 Fixed #20625 -- Chainable Manager/QuerySet methods. 
Additionally this patch solves the orthogonal problem that specialized
`QuerySet` like `ValuesQuerySet` didn't inherit from the current `QuerySet`
type. This wasn't an issue until now because we didn't officially support
custom `QuerySet` but it became necessary with the introduction of this new
feature.

Thanks aaugustin, akaariai, carljm, charettes, mjtamlyn, shaib and timgraham
for the reviews.
