This reverts commit 4fdd51b73240bf9c8d9472fcc45df699f0714755.
See the ticket for concerns with this implementation; it will be revisited.

Avoided introducing a new regex-based SQL splitter in the migrations
framework, before we're bound by backwards compatibility.
Adapted this change to the legacy "initial SQL data" feature, even
though it's already deprecated, in order to facilitate the transition
to migrations.
sqlparse becomes mandatory for RunSQL on some databases (all but
PostgreSQL). There's no API to provide a single statement and tell
Django not to attempt splitting. Since we have a more robust splitting
implementation, that seems like a good tradeoff. It's easier to add a
new keyword argument later if necessary than to remove one.
Many people contributed to both tickets, thank you all, and especially
Claude for the review.

Since all state is maintained on the connection at this time and none in
the atomic, it doesn't matter, but it could introduce some subtle bugs
if the implementation changed in the future.

As part of the app-loading updates the old test runner was changed to not
require a models module. This introduced a regression in behavior so
applabel.TestCase failed for tests defined in a directory.
The fix is thanks to yakky and rtnpro.
Forward ported code from 1.5 that adds backwards compatibility with legacy message length.
See commit 9e7183073f64e541587e8dcfd8bb3ddeb47f8162 for details.
Thanks to Ofir Ovadia for the initial patch.

Thanks Benjamin Bach for the report and initial patch.
This is a security fix; disclosure to follow shortly.

Changed the migration autodetector to remove models last so that FK
and M2M fields will not be left as dangling references. Added a check
in the migration state renderer to error out in the presence of
dangling references instead of leaving them as strings. Fixed a bug
in the sqlite backend to handle the deletion of M2M fields with
"through" models properly (i.e., do nothing successfully).
Thanks to melinath for report, loic for tests and andrewgodwin and
charettes for assistance with architecture.

The warning hint of `_check_test_runner` of 1.6 compatibility had a link
to a general release note. The link should be edited to refer the
relevant "Backwards incompatible changes in 1.6" section that documents
the cause and the possible solutions and workarounds of the warning.

3857 is now the official EPSG code for the Google spherical mercator
projection and some recent versions of GDAL do not recognize 900913
any longer.
Thanks Tim Graham for the report and initial patch.

Thanks intgr for the report.
This commit doesn't include a test because I don't know how to emulate a
database disconnection in a cross-database compatible way.
Also simplified a 'backends' test that was constrained by this problem.

Refs #15802 -- Reverted #7c657b24 as BaseDatabaseWrapper.close() now
has a proper "finally" clause that may need to preserve self.connection.
