Changeset 8131 for django/trunk/tests/regressiontests/model_regress

Message:

Fixed #7560 -- Moved a lot of the value conversion preparation for
loading/saving interactions with the databases into django.db.backend. This
helps external db backend writers and removes a bunch of database-specific
if-tests in django.db.models.fields.

Great work from Leo Soto.
