Fixed #11857 -- Added missing 'closed' property on TemporaryFile class.

- TemporaryFile now minimally mocks the API of the Python standard
  library class tempfile.NamedTemporaryFile to avoid AttributeError
  exceptions.
- The symbol django.core.files.NamedTemporaryFile is actually assigned
  as a different class on different operating systems.
- The bug only occurred if Django is running on Windows, hence why it
  was hard to diagnose.
Fixed versionadded and ordering of note in admin/index.txt
Added new AdminSite attributes to 1.7 release notes
Fixed #21049 -- Fixed autoreload for Python 3

a runtime error of "dictionary changed size during iteration".

Fixed #21043 -- Made resolve() handle reverse_lazy objects.

Thanks Keryn Knight for the report.
Fixed #20646 -- Clarified the use of AbstractBaseUser.REQUIRED_FIELDS

Thanks craigbruce.
Fixed some sphinx errors and added some links.
Added tests for missing pyyaml.

This test makes sure an YAML import errors are communicated to the
caller rather than stating the serializer does not exist.
Adding 'sqlmigrate' command and quote_parameter to support it.
Added yaml directly into BUILTIN_SERIALIZERS.

The serializer definitely exists, but the dependent yaml module may not
be installed.  The register_serializer() function will catch exceptions
and will stub in a fake serializer object that will raise the exception
when the serializer is used.
Moved get_serializer() call in dumpdata command.

Moved the get_serializer() call within the condition that checks public
serializers.  This will allow exceptions other than
SerializerDoesNotExist to be raised in order to provide the caller with
useful information, e.g when pyyaml is not installed.
