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.
Thanks Tim Graham for writing the docs.

Michal Petrucha c339a5a6f7 Refs #16508 -- Renamed the current "virtual" fields to "private". 
The only reason why GenericForeignKey and GenericRelation are stored
separately inside _meta is that they need to be cloned for every model
subclass, but that's not true for any other virtual field. Actually,
it's only true for GenericRelation.

Patryk Zawadzki 7628f87e2b Fixed #25750 -- Made Options._expire_cache() faster 
Avoided unnecessary list operations and delattr() calls that result
in an exception being raised as it causes call frame reconstruction
which is very costly, especially so in a function that is called
millions of times.

Anssi Kääriäinen 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.
