c1284c3d3c Fixed #20571 -- Added an API to control connection.needs_rollback. 
This is useful:
- to force a rollback on the exit of an atomic block without having to
  raise and catch an exception;
- to prevent a rollback after handling an exception manually.

6633eeb886 Changed API to disable ATOMIC_REQUESTS per view. 
A decorator is easier to apply to CBVs. Backwards compatibility isn't an
issue here, except for people running on a recent clone of master.

Fixed a few minor problems in the transactions docs while I was there.

83a416f5e7 Made atomic usable when autocommit is off. 
Thanks Anssi for haggling until I implemented this.

This change alleviates the need for atomic_if_autocommit. When
autocommit is disabled for a database, atomic will simply create and
release savepoints, and not commit anything. This honors the contract of
not doing any transaction management.

This change also makes the hack to allow using atomic within the legacy
transaction management redundant.

None of the above will work with SQLite, because of a flaw in the design
of the sqlite3 library. This is a known limitation that cannot be lifted
without unacceptable side effects eg. triggering arbitrary commits.

ac37ed21b3 Deprecated TransactionMiddleware and TRANSACTIONS_MANAGED. 
Replaced them with per-database options, for proper multi-db support.

Also toned down the recommendation to tie transactions to HTTP requests.
Thanks Jeremy for sharing his experience.

d7bc4fbc94 Implemented an 'atomic' decorator and context manager. 
Currently it only works in autocommit mode.

Based on @xact by Christophe Pettus.

5e27debc5c Enabled database-level autocommit for all backends. 
This is mostly a documentation change.

It has the same backwards-incompatibility consequences as those
described for PostgreSQL in a previous commit.

8312b85c97 Added support for savepoints to the MySQL DB backend. 
MySQL provides the savepoint functionality starting with version 5.0.3
when using the MyISAM storage engine.

Fixes #15507.

6314a1b42e Fixed #9964 -- Ensure that all database operations make transactions dirty, not just write operations. Many thanks to Shai Berger for his work and persistence on this issue. 
This is BACKWARDS INCOMPATIBLE for anyone relying on the current behavior that allows manually managed read-only transactions to be left dangling without a manual commit or rollback.

Congratulations to Alex for a job well done.

Ensure to read the documentation before blindly enabling this: requires some
