Merge NullBooleanField with BooleanField(allow_null=True) (#7122)
* Make `NullBooleanField` subclass `BooleanField`

This removes a lot of the redundancy that was in place becuase we
were not doing this. This maintains the `None` initial value that
was previously present, as well as disallowing `allow_null` to be
passed in.

* Remove special case for mapping `NullBooleanField`

In newer versions of Django, the `NullBooleanField` is handled the
same way as a `BooleanField(null=True)`. Given that we also support
that combination, and that our own `NullBooleanField` behaves in the
same manner, it makes sense to remove the special casing that exists
for it.

* Add test for BooleanField(null=True, choices)

* Remove special case for NullBooleanField

* Adjust mapping tests for NullBooleanField

* Fixed linting error

* Raise deprecation warning when NullBooleanField is used

* Fix linting issue in imports

d985c7cbb9 Remove a few no longer needed compat checks and references (#7092)
* serializers: removes no longer needed compat checks

UUIDField and DurationField are both supported in all supported Django
versions.

IPAddressField was removed in Django 1.9, which is no longer supported.

* serializers: move related code closer together

This way it's easier to see all of the mappings in one place.

* serializers,docs: remove some DRF 2.x references

The last release of DRF 2.x was 5 years ago, it seems fine to remove
these references now.

3242adf058 Enforce allow_empty=False during partial validation of parent serializer (#6512)
Refs #6509

This enforces allow_empty=True when a ListSerializer is a child of another serializer and partial validation is being performed on the parent serializer.

This is because partial validation should allow fields to be omitted, but should not cause values that are invalid without partial validation to become valid.

This effectively reverts #4222. None of the tests added in that PR fail if the associated change is removed, so I‘m not sure what that PR was trying to fix.

ccd9b71c0a Don't cache _readable_fields and _writable_fields (#6689)
It might be useful for a serializer with many many fields which uses
read_only and write_only on a large percentage of the fields. But the
memory usage and statefulness it adds are not worth it for the common
case.

3f19e66d9f Replace all usage ugettext functions with the non-u versions (#6634)
On Python 3, the ugettext functions are a simple aliases of their non-u
counterparts (the 'u' represents Python 2 unicode type). Starting with
Django 3.0, the u versions will be deprecated.

https://docs.djangoproject.com/en/dev/releases/3.0/#id2

> django.utils.translation.ugettext(), ugettext_lazy(), ugettext_noop(),
> ungettext(), and ungettext_lazy() are deprecated in favor of the
> functions that they’re aliases for:
> django.utils.translation.gettext(), gettext_lazy(), gettext_noop(),
> ngettext(), and ngettext_lazy().

ffe3dbb1b1 Perfer iter(dict) over iter(dict.keys()) (#5736)
Calling dict.keys() is unnecessary. The two are functionally equivalent
on modern Pythons.

PyCon 2017.

Set literals are available on all supported Python versions. They are

$ python3 -m timeit 'dict()'
10000000 loops, best of 3: 0.104 usec per loop

$ python3 -m timeit '{1, 2, 3}'
10000000 loops, best of 3: 0.0754 usec per loop
$ python3 -m timeit 'set([1, 2, 3])'

4c2d6b9bb7 Do not ignore source when building fields dynamically
This commit fixes the issue when you set the keyword argument `source`
and your have not set the serializer fields explicitly. Then the
construction of field failed because there is not actually any model
field with that name.

However, you are still able to imply the name of model field by
providing the `source` keyword argument.
