Without this, Django's ValidationErrors will bypass the error collection
from ListField's children.
Here is an example that illustrates this change.
Consider a Serializer that uses ListField like this:
```python
class SomeSerializer(serializers.Serializer):
uuids = serializers.ListField(
child=serializers.PrimaryKeyRelatedField(
queryset=Model.objects.something(),
validators=[SomeCustomValidator()]
)
)
```
Validating data that looks like this works fine:
```python
{uuids: ['some-valid-uuid', 'some-valid-uuid']}
```
Raising a DRF ValidationError for one of the children works fine, giving
an error object like:
```python
{'uuids': {0: ErrorDetail(string='Some validation error')}}
```
Raising a Django ValidationError for one of the children works
differently (which serializers.PrimaryKeyRelatedField can do in some
cases, like when the uuid is malformed). It gives an error object like:
```python
{'uuids': ["'X' is not a valid UUID."]}
```
Handling Django's ValidationErrors in ListField explicitly (like in this
pull request), will maintain a regular error interface in this case:
```python
{'uuids': {0: ErrorDetail(string="'X' is not a valid UUID.")}}
```
Scripts with type="application/json" or "text/plain" are not executed, so we can
use them to inject dynamic CSRF data, without allowing inline-script execution
in Content-Security-Policy.

Importing anything `rest_framework` causes `django.test` to be imported.
This is because DRF registers a receiver on the
`django.test_signals.setting_changed` signal.
This is not really a problem, but it is good to avoid this because it
bloats the memory with unnecessary modules (e.g. `django.test`,
`django.core.servers.basehttp`, `socketserver`) and increases the
startup time. It also doesn't feel right to import test code into
non-test code.
Try to import the signal from a core module if possible.
Note that there's another `django.test` import in `MultiPartRenderer`,
however this import is done lazily only if the functionality is used so
can be easily avoided.
`PendingDeprecationWarning` means "we plan to deprecate, but haven't
yet." A feature that's to be deleted in the next release is not planned
to be deprecated; it **is** deprecated.
> Base class for warnings about features which are obsolete and expected
> to be deprecated in the future, but are not deprecated at the moment.
>
> This class is rarely used as emitting a warning about a possible
> upcoming deprecation is unusual, and DeprecationWarning is preferred for
> already active deprecations.

When DRF 3.14 is released, these exception classes will be meaningless,
so we can delete them (this has always been done).
A previous PR removed the last incidence of `RemovedInDRF313Warning`,
but didn't outright delete the class for fear of shipping a breaking

* Remove deprecated NullBooleanField.
* Change openapi _get_reference removal to 3.15
This deprecation was never released in the 3.13.x series and therefore
can't be removed at the same time the replacement is released.

* Change semantic of OR of two permission classes
The original semantic of OR is defined as: the request pass either of the two has_permission() check, and pass either of the two has_object_permission() check, which could lead to situations that a request passes has_permission() but fails on has_object_permission() of Permission Class A, fails has_permission() but passes has_object_permission() of Permission Class B, passes the OR permission check. This should not be the desired permission check semantic in applications, because such a request should fail on either Permission Class (on Django object permission) alone, but passes the OR or the two.
My code fix this by changing the semantic so that the request has to pass either class's has_permission() and has_object_permission() to get the Django object permission of the OR check.

* Fixes that namespaced views now also appear in the extra actions
Before this fix, namespaced views would not appear in the extra actions. With this fix they do.
* Flake fix
Per the deprecation warnings (which have been raised since DRF 3.11),
`set_context()` was planned not to be supported in DRF 3.13. I think we
can safely delete it, in favor of `requires_context`.
From the 3.11 announcement:
> Previous our approach to this was that implementations could include a
> `set_context` method, which would be called prior to validation. However
> this approach had issues with potential race conditions. We have now
> move this approach into a pending deprecation state. It will continue to
> function, but will be escalated to a deprecated state in 3.12, and
> removed entirely in 3.13.
Why keep `RemovedInDRF313Warning` around?
=========================================
It's a bit odd that version 3.13 includes an exception class describing
things which are to be deleted in 3.13, but I've opted to keep the (now
unreferenced) class around, for fear of breaking others' setup.
(For example, if projects have a `filterwarnings` setup meant to
intercept `rest_framework.RemovedInDRF313Warning`, an error will be
thrown due to an unresolvable reference).
PR #7531 resolved issue #7433 by updating `ErrorDetails.__eq__` to correctly
handle the `NotImplemented` case. However, Python 3.9 continues to issue the
following warning:
DeprecationWarning: NotImplemented should not be used in a boolean context
This is because `__ne__` still doesn't handle the `NotImplemented` case
correctly. In order to avoid this warning, this commit makes the same change
for `__ne__` as previously made for `__eq__`.
Add a backwards compatibility shim for Django versions that have no (or an incompatible)
django.utils.http.parse_header_parameters implementation.
