In some cases we end with an operation between two `OperandHolder`.
This didn't work as it didn't knew how to deal with | or &
This fixes by adding those operations.
`x and y` actually returns object y when both are true. the means P & IsAuthenticated will fail with TypeError: unsupported operand type(s) for &: 'instance' and 'bool' as IsAuthenticated now returns a CallableBool which does not overload __ror__
* permissions: Allow permissions to be composed
Implement a system to compose permissions with and / or.
This is performed by returning an `OperationHolder` instance that keeps the
permission classes and type of composition (and / or).
When called it will return a AND/OR instance that will then delegate the
permission check to the operands.
* permissions: Add documentation about composed permissions
* Fix documentation typo in permissions
* Identify code that needs to be pulled out of/removed from compat.py
* Extract modern code from get_names_and_managers in compat.py and remove compat code
* Extract modern code from is_authenticated() in compat.py and remove.
* Extract modern code from is_anonymous() in compat.py and remove
* Extract modern code from get_related_model() from compat.py and remove
* Extract modern code from value_from_object() in compat.py and remove
* Update postgres compat
JSONField now always available.
* Remove DecimalValidator compat
* Remove get_remote_field compat
* Remove template_render compat
Plus isort.
* Remove set_many compat
* Remove include compat
Quietly catching `AttributeError` and `TypeError` when calling
`get_queryset()` is rather insidious, as those exceptions get caught no
matter where they might happen in the call stack.
