Pickling a `SimpleLazyObject` wrapping a model did not work correctly; in
particular it did not add the `_django_version` attribute added in 42736ac8.
Now it will handle this and other custom `__reduce__` methods correctly.

This commits lifts the restriction that the outermost atomic block must
be declared with savepoint=False. This restriction was overly cautious.
The logic that makes it safe not to create savepoints for inner blocks
also applies to the outermost block when autocommit is disabled and a
transaction is already active.
This makes it possible to use the ORM after set_autocommit(False).
Previously it didn't work because ORM write operations are protected
with atomic(savepoint=False).

Too much field exclusions in form's construct_instance() in _post_clean()
could lead to some unexpected missing ForeignKey values.
Fixes a regression from 45e049937. Refs #13776.

Moved data loss check when assigning to a reverse one-to-one relation on
an unsaved instance to Model.save(). This is exactly the same change as
e4b813c but for reverse relations.

This also fixes a test failure on Python 2 when Django is installed in a
non-ASCII path. This problem cannot happen on Python 3.

* Added helpers to test uncached and cached access.
* Fixed test_project_root_locale: it duplicated test_locale_paths_setting.

* When some old files contain errors, the second call to
gen_filenames() should return them.
* When some new files contain errors, the first call to
gen_filenames(only_new=True) should return them.

Ensured squashed migrations are recorded as applied when the
migrate command is run and all of the original migrations
have been previously applied.

Django ignores the value of the TEMPLATE_* settings if TEMPLATES is also
set, which is confusing for users following older tutorials. This change
adds a system check that warns if any of the TEMPLATE_* settings have
changed from their defaults but the TEMPLATES dict is also non-empty.
Removed the TEMPLATE_DIRS from the test settings file; this was marked
for removal in 1.10 but no tests fail if it is removed now.

Thanks João Silva for reporting the problem and Tim Graham for finding the
problematic RE and for review.
This is a security fix; disclosure to follow shortly.
The session record is now only created if/when the session is modified. This
prevents a potential DoS via creation of many empty session records.
This is a security fix; disclosure to follow shortly.
