Clarified interactions between atomic and exceptions.

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.

Allowed nesting constraint_checks_disabled inside atomic.
Since MySQL handles transactions loosely, this isn't a problem.
commit 2a4ab1cb6e83391ff7e25d08479e230ca564bfef

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.
* Move the discussion of CachedStaticFilesStorage to the section about
HTTP. It's really about client-side caching. It doesn't fit with the
caching utilities from django.utils.functional.
* Tone down the warning against Pypy as per Alex' feedback. It's a valid
choice for advanced users who are comfortable using a non-standard
stack.
* Generally reworded the 'Using different versions of available software'
section.
* Some other minor adjustments to the document.
- Fixed some grammar and formatting mistakes
- Added the type and default for CULL_FREQUENCY
- Made the note on culling the entire cache more precise. (It's actually
slower on the filesystem backend.)
* override_settings may now be imported from django.test
* removed Approximate from django.test
* updated documentation for things importable from django.test
Thanks akaariai for the suggestion.
Added settings.SESSION_SERIALIZER which is the import path of a serializer
to use for sessions.
Thanks apollo13, carljm, shaib, akaariai, charettes, and dstufft for reviews.
