Russell Keith-Magee f0d75dbe3e Fixed #10833 -- Corrected load_backend so that it actually loads the requested backend, rather than always loading settings.DATABASE_BACKEND. Thanks to Alex Gaynor for the report and fix.

Jacob Kaplan-Moss c485e236bd Fixed #8193: all dynamic imports in Django are now done correctly. I know this because Brett Cannon borrowed the time machine and brought Python 2.7's '`importlib` back for inclusion in Django. Thanks for the patch-from-the-future, Brett!

Adrian Holovaty 315145f7ca Fixed #10459 -- Refactored the internals of database connection objects so that connections know their own settings and pass around settings as dictionaries instead of passing around the Django settings module itself. This will make it easier for multiple database support. Thanks to Alex Gaynor for the initial patch.
This is backwards-compatible but will likely break third-party database backends. Specific API changes are:

* BaseDatabaseWrapper.__init__() now takes a settings_dict instead of a settings module. It's called settings_dict to disambiguate, and for easy grepability. This should be a dictionary containing DATABASE_NAME, etc.

* BaseDatabaseWrapper has a settings_dict attribute instead of an options attribute. BaseDatabaseWrapper.options is now BaseDatabaseWrapper['DATABASE_OPTIONS']

* BaseDatabaseWrapper._cursor() no longer takes a settings argument.

* BaseDatabaseClient.__init__() now takes a connection argument (a DatabaseWrapper instance) instead of no arguments.

Malcolm Tredinnick 98be841549 Fixed #8238 -- If an invalid database backend is mentioned in settings and the
environment doesn't support os.listdir(), we crashed whilst trying to construct
the friendly error message. This was not so friendly.

This patch handles that case (which occurs in real life in Google App Engine).
Patch from Guido van Rossum.

Malcolm Tredinnick 844089de07 Fixed #8315 -- If an exception is raised whilst trying to rollback a
transaction (after another exception in the code), make sure the original
exception is reported, rather than the rollback-generated one. The latter is
almost certainly a consequence of the former. Patch from Karen Tracey.

Jacob Kaplan-Moss 34a3bd5225 Major refactoring of django.dispatch with an eye towards speed. The net result is that signals are up to 90% faster.
Though some attempts and backwards-compatibility were made, speed trumped compatibility. Thus, as usual, check BackwardsIncompatibleChanges for the complete list of backwards-incompatible changes.

Thanks to Jeremy Dunck and Keith Busell for the bulk of the work; some ideas from Brian Herring's previous work (refs #4561) were incorporated.

Documentation is, sigh, still forthcoming.

Fixes #6814 and #3951 (with the new dispatch_uid argument to connect).
