Merge branch 'master' of git://github.com/django/django

Ensued that SQL indexes are alwasy created in the same name.

Previous this used Python's builtin hash() function, which has never been guarnteed to be stable across implementations (CPython/Jython/etc.) or 32/64 bitness. However, this in practice it was stable. However, with the impending release of Python 3.3 hash randomizations is enabled by default, which would mean the index name changed between program invocations.
Fixed #17888 -- no longer silence exceptions inside of check_test. Thanks to brutasse for the patch.
