Fixed #29908 -- Fixed setting of foreign key after related set access if ForeignKey uses to_field.
...
Adjusted known related objects handling of target fields which relies on
from and to_fields and has the side effect of fixing a bug bug causing
N+1 queries when using reverse foreign objects.
Thanks Carsten Fuchs for the report.

Using lowercased model class names suggested that accessing the attribute
from instances of the class returned an instance of the descriptor, but
this is only the case when accessed from the model class.

The old names were downright confusing. Some seemed to mean the opposite
of what the class actually did.
The new names follow a consistent nomenclature:
(Forward|Reverse)(ManyToOne|OneToOne|ManyToMany)Descriptor.
I mentioned combinations that do not exist in the docstring in order to
help people who would search for them in the code base.
