Anssi Kääriäinen 1893467784 Fixed #19274 -- Made db connection creation overridable in subclasses
Connection creation was done in db backend ._cursor() call. This
included taking a new connection if needed, initializing the session
state for the new connection and finally creating the connection.

To allow easier modifying of these steps in subclasses (for example to
support connection pools) the _cursor() now calls get_new_connection()
and init_connection_state() if there isn't an existing connection. This
was done for all non-gis core backends. In addition the parameters used
for taking a connection are now created by get_connection_params().

We should also do the same for gis backends and encourage 3rd party
backends to use the same pattern. The pattern is not enforced in code,
and as the backends are private API this will not be required by
documentation either.

Ramiro Morales f758bdab5e Fixed #18271 -- Changed stage at which TransactionTestCase flushes DB tables.
Previously, the flush was done before the test case execution and now
it is performed after it.

Other changes to the testing infrastructure include:

* TransactionTestCase now doesn't reset autoincrement sequences either
  (previous behavior can achieved by using `reset_sequences`.)
  With this, no implicit such reset is performed by any of the provided
  TestCase classes.

* New ordering of test cases: All unittest tes cases are run first and
  doctests are run at the end.

THse changes could be backward-incompatible with test cases that relied
on some kind of state being preserved between tests. Please read the
relevant sections of the release notes and testing documentation for
further details.

Thanks Andreas Pelme for the initial patch. Karen Tracey and Anssi
Kääriäinen for the feedback and Anssi for reviewing.

This also fixes #12408.

Anssi Kääriäinen a18e43c5bb Made get_indexes() consistent across backends.
Fixed #15933, #18082 -- the get_indexes() method introspection was
done inconsitently depending on the backend. For example SQLite
included all the columns in the table in the returned dictionary,
while MySQL introspected also multicolumn indexes.

All backends return now consistenly only single-column indexes.

Thanks to andi for the MySQL report, and ikelly for comments on
Oracle's get_indexes() changes.

Ramiro Morales 287565779d Added support for modifying the effect of ``DISTINCT`` clauses so they
only consider some fields (PostgreSQL only).

For this, the ``distinct()`` QuerySet method now accepts an optional
list of model fields names and generates ``DISTINCT ON`` clauses on
these cases. Thanks Jeffrey Gelens and Anssi Kääriäinen for their work.

Fixes #6422.

Aymeric Augustin 549c495875 Used symbolic constants for psycopg2 isolation levels.
Django used the value 1 = ISOLATION_LEVEL_READ_UNCOMMITTED in some places, but
PostgreSQL doesn't provide "read uncommited", it uses "read committed" instead:
http://www.postgresql.org/docs/9.1/static/transaction-iso.html. For clarity,
this commit uses ISOLATION_LEVEL_READ_COMMITTED = 2 where 1 was previously used.

Ramiro Morales 569aa34ea5 Fixed #16250 -- Made test database creation support code in the PostgreSQL DB backend compatible with psycopg2 2.4.2.
Implemented this by adding an internal hook for work that should be performed
before that point.

Also, regarding the `DatabaseCreation.set_autocommit()` method:
 * Stop using it for such tasks
 * Stop providing an implementation that tries to cover all the possible
   idioms a third party database backend DB-API 2 driver could need to activate
   autocommit. It is now left for third party backends to implement.

This can be backwards incompatible in the case of user applications that:
 * Had started using this method
 * Use a third a party database backend

Ramiro Morales f2dca72afd Fixed #11065, #11285 -- Streamlined PostgreSQL version detection, fixing incompatibility with multi-db. Thanks findepi for the report.
Changed our internal representation of the PostgreSQL version from tuples to
integers as used by libpq and psycopg2. This simplifies version comparison
operations.

Also, using the associated libpq/psycopg2 API allows to remove the need for
manually issuing in-band ``SELECT version()`` SQL queries to obtain the server
version (or at least reduce its number if version of psycopg2 in use is older
than 2.0.12). Refs #10509.
