When a FileField value has been saved, a new validation should not
regenerate a new filename when checking the length. Refs #9893.

This commit tackles a couple of issues. First, in certain cases there
were some mixups if field.attname or field.name should be deferred.
Field.attname is now always used.

Another issue tackled is a case where field is both deferred by
.only(), and selected by select_related. This case is now an error.

A lot of thanks to koniiiik (Michal Petrucha) for the patch, and
to Andrei Antoukh for review.

Thanks Rob Golding for helping on the patch.

Thanks aldaran for the patch.

Added ability to use receiver decorator in the following way:

    @receiver([post_save, post_delete], sender=MyModel)
    def signals_receiver(sender, **kwargs):
        ...

``include`` calls shouldn't have a $ sign at the end of the url pattern.

django.core.context_processors.tz was missing from default
TEMPLATE_CONTEXT_PROCESSORS in the template api documentation.

Thanks to ambv for the report

Thanks volrath and copelco for their work on the patch.

Previously, the closing token for the verbatim tag was specified as the
first argument of the opening token. As pointed out by Jannis, this is
a rather major departure from the core tag standard.

The new method reflects how you can give a specific closing name to
{% block %} tags.

Moved HAS_SPATIALREFSYS back into the tests namespace since it only operates
on the default database and isn't a global flag like HAS_GDAL.
