Introduced an AbstractBaseSession model and hooks providing the option
of overriding the model class used by the session store and the session
store class used by the model.
The session record is now only created if/when the session is modified. This
prevents a potential DoS via creation of many empty session records.
This is a security fix; disclosure to follow shortly.
Changed _session_key attribute to a property and implemented basic
validation in the setter. The session key must be 'truthy' and
at least 8 characters long. Otherwise, the value is set to None.
Changed SessionBase.pop's second argument to explicitly be default=None
rather than *args since _session is always a dict. Thanks gabor for the
report and Tim Graham for the review.
Previously, when logging out, the existing session was overwritten by a
new sessionid instead of deleting the session altogether.
This behavior added overhead by creating a new session record in
whichever backend was in use: db, cache, etc.
This extra session is unnecessary at the time since no session data is
meant to be preserved when explicitly logging out.
Thanks Curtis Malony and Florian Apolloner.

Fixed TransactionManagementError in tests.
Previous commit introduced an additional check to prevent running
queries in transactions that will be rolled back, which triggered a few
failures in the tests. In practice using transaction.atomic instead of
the low-level savepoint APIs was enough to fix the problems.
commit 4a639b059ea80aeb78f7f160a7d4b9f609b9c238

Allowed nesting constraint_checks_disabled inside atomic.
Since MySQL handles transactions loosely, this isn't a problem.
commit 2a4ab1cb6e83391ff7e25d08479e230ca564bfef
Author: Aymeric Augustin <aymeric.augustin@m4x.org>

Prevented running queries in transactions that will be rolled back.
This avoids a counter-intuitive behavior in an edge case on databases
with non-atomic transaction semantics.
It prevents using savepoint_rollback() inside an atomic block without
calling set_rollback(False) first, which is backwards-incompatible in
tests.

commit 8e3db393853c7ac64a445b66e57f3620a3fde7b0
Author: Aymeric Augustin <aymeric.augustin@m4x.org>
Date: Sun Sep 22 22:14:17 2013 +0200
Replaced manual savepoints by atomic blocks.
This ensures the rollback flag is handled consistently in internal APIs.
Added settings.SESSION_SERIALIZER which is the import path of a serializer
to use for sessions.
