Fixed #20117 -- Added missing translation override to fix flatpages test.
Fixed #9055 -- Standardized behaviour of parameter escaping in db cursors

Previously, depending on the database backend or the cursor type,
you'd need to double the percent signs in the query before passing
it to cursor.execute. Now cursor.execute consistently need percent
doubling whenever params argument is not None (placeholder substitution
will happen).
Thanks Thomas Güttler for the report and Walter Doekes for his work
on the patch.

Fixed #17550 -- Removed a workaround for a bug in flup 1.0.1.

This reverts commit 948a833eb7fd9be0bc2d585c92a407f036ef42b2.

flup appears to be dead, and this fix breaks legitimate uses of Django.

Fixed 19385 -- Added ORM support for multicolumn joins

This patch iproved two major parts in Django. First, the fields.related
was refactored. The main addition there was ForeignObject. Second, the
ORM now handles multicolumn joins in most cases, though there are still
cases that do not work correcly (split_exclude() for example).

In addition there were extesive changes to how GenericRelation works.
Before it was a fake m2m field, now it is a pure virtual fields and is
based on ForeignObject.

There is still much room for improvement. The related fields code is
still somewhat confusing, and how fields are represented in model._meta
should also be revisited.

This patch was written mostly by Jeremy Tillman with some final polish
by the committer.
Doc: "value" is arg not kwarg in HttpResponse.set_signed_cookie
