Russell Keith-Magee 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.

Russell Keith-Magee d1cd53d9cf Changeset r15232 refactored transactions so that all transaction state is maintained on the connection. This changeset continues that work, moving all transaction control to the connection, too. The transaction control functions in django.db.transaction are left as a generic way to easily apply a transaction control function based on a DB alias. Refs #9964.

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 a1cbeb9afb If an SQL query doesn't specify any ordering, avoid the implicit sort
that happens with MySQL when a "GROUP BY" clause is included. This is a
backend-specific operation, so any other databases requiring similar
encouragement can have a function added to their own backend code.

Malcolm Tredinnick 220993bcc5 Added savepoint support to the transaction code.
This is a no-op for most databases. Only necessary on PostgreSQL so that we can
do things which will possibly intentionally raise an IntegrityError and not
have to rollback the entire transaction. Not supported for PostgreSQL versions
prior to 8.0, so should be used sparingly in internal Django code.
