2f121dfe63 Fixed #17051 -- Removed some 'invalid' field error messages 
When the 'invalid' error message is set at field level, it masks
the error message raised by the validator, if any.

6b4834952d Fixed #16649 -- Refactored save_base logic 
Model.save() will use UPDATE - if not updated - INSERT instead of
SELECT - if found UPDATE else INSERT. This should save a query when
updating, but will cost a little when inserting model with PK set.

Also fixed #17341 -- made sure .save() commits transactions only after
the whole model has been saved. This wasn't the case in model
inheritance situations.

The save_base implementation was refactored into multiple methods.
A typical chain for inherited save is:
save_base()
    _save_parents(self)
        for each parent:
            _save_parents(parent)
            _save_table(parent)
    _save_table(self)

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.

3bdc7a6a70 Deprecated transaction.is_managed(). 
It's synchronized with the autocommit flag.

ba5138b1c0 Deprecated transaction.commit/rollback_unless_managed. 
Since "unless managed" now means "if database-level autocommit",
committing or rolling back doesn't have any effect.

Restored transactional integrity in a few places that relied on
automatically-started transactions with a transitory API.

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.

7aacde84f2 Made transaction.managed a no-op and deprecated it. 
enter_transaction_management() was nearly always followed by managed().

In three places it wasn't, but they will all be refactored eventually.
The "forced" keyword argument avoids introducing behavior changes until
then.

This is mostly backwards-compatible, except, of course, for managed
itself. There's a minor difference in _enter_transaction_management:
the top self.transaction_state now contains the new 'managed' state
rather than the previous one. Django doesn't access
self.transaction_state in _enter_transaction_management.
