Keryn Knight a697424969 Fixed #32996 -- Cached PathInfos on relations. 
PathInfo values are ostensibly static over the lifetime of the object
for which they're requested, so the data can be memoized, quickly
amortising the cost over the process' duration.

Tom Forbes b5e12d490a Fixed #31007 -- Allowed specifying type of auto-created primary keys.

Simon Charette 1d16c5d562 Refs #27666 -- Ensured relationship consistency on delayed reloads. 
Delayed reloads of state models broke identity based relationships
between direct and non-direct ancestors.

Basing models.Options related objects map of model labels instead of
their identity ensured relationship consistency is maintained.

Refs #30966.

Fixed #29998 -- Allowed multiple OneToOneFields to the parent model. 
We assumed that any OneToOneField's in a child model must be the
parent link and raised an error when parent_link=True was not
specified. This patch allows to specify multiple OneToOneField's to
the parent model.

OneToOneField's without a custom related_name will raise fields.E304
and fields.E305 so this should warn users when they try to override
the auto-created OneToOneField.

Adam Chainz d2a26c1a90 Optimized Model instantiation a bit. 
* Avoid some unnecessary attribute lookups, e.g. access signals directly rather than from module
* Alias some repeat accesses inside the method to use the slightly faster local lookups
* Use tuple to iterate remaining kwargs as it's faster to construct
* Cache Field.get_default() to avoid running through all the logic on every call
* Use a cached list of the properties on the model class to avoid repeat isinstance() calls

Loïc Bistuer ed0ff913c6 Fixed #10506, #13793, #14891, #25201 -- Introduced new APIs to specify models' default and base managers. 
This deprecates use_for_related_fields.

Old API:

class CustomManager(models.Model):
    use_for_related_fields = True

class Model(models.Model):
    custom_manager = CustomManager()

New API:

class Model(models.Model):
    custom_manager = CustomManager()

    class Meta:
        base_manager_name = 'custom_manager'

Refs #20932, #25897.

Thanks Carl Meyer for the guidance throughout this work.
