Russell Keith-Magee 7d03ca9e86 Fixed #10161 -- Modified evaluation of query expressions to allow for operators that take the form of functions. This is mostly for the benefit of Oracle, but it should prove useful later on. Thanks to Ian for the report and feedback on the fix.

Russell Keith-Magee 542709d0d1 Fixed #10182 -- Corrected realiasing and the process of evaluating values() for queries with aggregate clauses. This means that aggregate queries can now be used as subqueries (such as in an __in clause). Thanks to omat for the report.
This involves a slight change to the interaction of annotate() and values() clauses that specify a list of columns. See the docs for details.

Karen Tracey 11bfe72366 Fixed #10121: Restored code lost in r9766 that prevented overwriting an already-set blank=True FileField with blank. This would happen, for instance, in the admin if an object with a FileField was edited/saved but the file not re-uploaded, resulting in the association to the previously-uploaded file being lost. Adding the ability to re-blank FileFields when they are once set is the subject of a different ticket (#7048), for now the pre-9766 behavior here has just been restored in order to avoid unexpected data loss. Thanks to Alex for help in understanding how to fix this without un-doing the intent of r9766.

Karen Tracey 344f16e220 Fixed #8138 -- Changed django.test.TestCase to rollback tests (when the database supports it) instead of flushing and reloading the database. This can substantially reduce the time it takes to run large test suites.
This change may be slightly backwards incompatible, if existing tests need to test transactional behavior, or if they rely on invalid assumptions or a specific test case ordering.  For the first case, django.test.TransactionTestCase should be used.  TransactionTestCase is also a quick fix to get around test case errors revealed by the new rollback approach, but a better long-term fix is to correct the test case.  See the testing doc for full details.

Many thanks to:
* Marc Remolt for the initial proposal and implementation.
* Luke Plant for initial testing and improving the implementation.
* Ramiro Morales for feedback and help with tracking down a mysterious PostgreSQL issue.
* Eric Holscher for feedback regarding the effect of the change on the Ellington testsuite.

Malcolm Tredinnick f747b61c20 Nested query support.
This extends previous functionality that allowed passing Query objects as the
rvals to filters. You can now pass QuerySets, which requires less poking at
opaque attributes. See the documentation of the "__in" lookup type for the
details.

Malcolm Tredinnick 062a94ef45 Reconciling where- and having-clause behaviour.
Extricated the code that works directly with SQL columns (standard
"where" stuff) from the the code that takes SQL fragments and combines
it with lookup types and values. The latter portion is now more
generally reusable. Any existing code that was poking at Query.having
will now break in very visible ways (no subtle miscalculations, which is
a good thing).

This patch, en passant, removes the existing "having" test, since the
new implementation requires more setting up than previously. The
aggregates support (currently in a separate codebase) has tests for this
functionality that work as a replacement for the removed test.
