Merge branch 'exception-handler-context' of git://github.com/jpadilla/django-rest-framework into jpadilla-exception-handler-context

Same context as renderers which include: the view,
args, kwargs, and request.

This provides enough contextual information to the
exception handlers to handle errors better.

In a use case like #1671, a custom handler
would allow Sentry to log the request properly.

Change serializers.Field to serializers.ReadOnlyField for 3.x compatibility

Using this code snippet as-is on DRF 3.0.1 results in a NotImplementedError
being raised for to_representation due to 3.0's changed behavior with
serializers.Field. The code snippet should be updated to use
serializers.ReadOnlyField instead.

Further discussion here:

Better errors when serializer has incorrectly named field.

Improve error checking for nested writes.
