254df3a3bb Fixed #34791 -- Fixed incorrect Prefetch()'s cache for singly related objects. 
Changed the cache name used for singly related objects to be the
to_attr parameter passed to a Prefetch object. This fixes issues with
checking if values have already been fetched in cases where the Field
already has some prefetched value, but not for the same model attr.

Fixed #33984 -- Reverted "Fixed #32980 -- Made models cache related managers." 
This reverts 4f8c7fd9d9 and adds
two regression tests:
- test_related_manager_refresh(), and
- test_create_copy_with_m2m().

Thanks joeli for the report.

Relaxed some query ordering assertions in various tests. 
It accounts for differences seen on MySQL with MyISAM storage engine.

Removed redundant QuerySet.all() calls in docs and tests. 
Most QuerySet methods are mapped onto the Manager and, in general,
it isn't necessary to call .all() on the manager.

Refs #33476 -- Refactored problematic code before reformatting by Black. 
In these cases Black produces unexpected results, e.g.

def make_random_password(
    self,
    length=10,
    allowed_chars='abcdefghjkmnpqrstuvwxyz' 'ABCDEFGHJKLMNPQRSTUVWXYZ' '23456789',
):

or

cursor.execute("""
SELECT ...
""",
    [table name],
)

f5233dce30 Fixed #32511 -- Corrected handling prefetched nested reverse relationships. 
When prefetching a set of child objects related to a set of parent
objects, we usually want to populate the relationship back from the
child to the parent to avoid a query when accessing that relationship
attribute. However, there's an edge case where the child queryset
itself specifies a prefetch back to the parent. In that case, we want
to use the prefetched relationship rather than populating the reverse
relationship from the parent.

assertSequenceEqual()/assertCountEqual() where appropriate.

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.

54ea290e5b Fixed #30651 -- Made __eq__() methods return NotImplemented for not implemented comparisons. 
Changed __eq__ to return NotImplemented instead of False if compared to
an object of the same type, as is recommended by the Python data model
reference. Now these models can be compared to ANY (or other objects
with __eq__ overwritten) without returning False automatically.
