sqlall will be removed in Django 1.9, so now's a good time to remove
its usage where it's not important.

Initial SQL data will be removed in Django 1.9 so changes to it
aren't relevant.

This removes the need to load django.test when not testing.

The migrations autodetector now issues AlterModelOptions operations for
Meta.managed changes instead of DeleteModel + CreateModel.

Thanks iambibhas for the report and Simon and Markus for review.

Also used schema editor in migrate to sync unmigrated apps (sync_apps).
Refs #22340. Thanks Tim Graham for the review.

Based on Daniel Wiesmann's raster branch. Thanks Daniel Wiesmann
and Tim Graham for the reviews. Refs #23804.

Thanks Philip Mountifield for the report and excellent analysis, and
Simon Charette for the review.

A test failed on Python 2 32-bit.

This reduces how frequently this logic is run significantly.

Thanks to Anssi for the suggestion.

Use INTERVAL DAY(9) TO SECOND(6) for Durationfield on Oracle rather than
storing as a NUMBER(19) of microseconds.

There are issues with cx_Oracle which require some extra data
manipulation in the database backend when constructing queries, but it
handles the conversion back to timedelta objects cleanly.

Thanks to Shai for the review.
