These files were added as part of #12658, which pertained to the old django.test.simple test runner. No tests call them anymore.

Thanks Jon Foster for the report.

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.

Thanks tobami at gmail.com for the report.

Binary mode added in ed532a6a is not supported by ZipFile.
Refs #22399.

This might help on systems where default encoding is not UTF-8 (and
on Python 3).
Thanks bacilla for the report.

Thanks to aruseni for the report.

Fixed #22464 - included contrib/gis/static in tarball

After switching to setuptools in commit 66f546b9,
contrib/gis/static isn't included in tarball anymore, this commit adds
that path to be `recursive-include` in `MANIFEST.in`

This reverts commit 00e3b9a2.

It's causing a regression when tested with the proxy_model_inheritance tests.

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.

Thanks Karen Tracey for the report.

Thanks Loic for the report.

Use the stdlib's PBKDF2 implementation when available.

Include an 'extra_requires' for bcrypt

Refs #22456.

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.

This is a bit faster than ours, which is good, because it lets you increase
the iteration counts.

This will be used on Python 3.4+, and, pending the acceptance of PEP466, on
newer Python 2.7s.

Revert "Fixed #22401 -- Deprecated regular expression parsing of initial SQL in favor of installing sqlparse."

This introduced a regression on MySQL and custom SQL is deprecated.

Thanks tomwys for the suggestion.

Thanks EvilDMP for the suggestions.

Thanks maciej.pawlisz for the report, and charettes for the review.
