Fixed #22626 -- Allow BinaryField defaults with SQlite.

Also fixes a slight issue in sqlite3.schema._remake_table where
default values where quoted with "column name" quoting rules.

Reference for quoting: http://www.sqlite.org/lang_expr.html

Thanks Shai Berger for the review. Refs #22424.
Fixed several flake8 errors, including one where a test wouldn't be run
Fixed #6668 -- Optimized utils.text wrap function

This fixes a failing test after applying an optimization of the
utils.text.wrap function by user SmileyChris.
Moved wordwrap test to their own function

The `wordwrap` tests were in the `test_wordcount()` method for some
reason. This moves them to their own method, and make consistent use of
double quotes where needed.
Fixed #22421 -- Regression in fixtures loading.

Loading fixtures were failing since the refactoring in 244e2b71f5 for
inheritance setups where the chain contains abstract models and the
root ancestor contains a M2M relation.

Thanks Stanislas Guerra for the report.

Refs #20946.
Fixed #22424 -- Fixed handling of default values for TextField/BinaryField on MySQL.

Thanks syphar for the review and suggestions.
Failing testcases for #22649.

Updated Django makemessages process

makemessages should now automatically distribute translatable
strings in the proper locale files, for Django too
(see 50a8ab7cd1e6).
Fixed #22368 -- clarified connecting to Oracle DB using service name

Used the official terminology listed in
http://docs.oracle.com/cd/B19306_01/network.102/b14212/glossary.htm#i997309

Thanks michael.cherkasov for the report.
Fixed #20477: Allowed settings.FORMAT_MODULE_PATH to be a list of modules.

Previously the FORMAT_MODULE_PATH setting only accepted one string (dotted
module path).

This is useful when using several reusable third party apps that define new
formats. We can now use them all and we can even override some of the formats
by providing a project-wide format module.
Removed locale dirs for single-message apps

Considering that these apps only translate their app name, it's not
worth having a whole bunch of po files just for that. The translatable
app name for those apps will be integrated in Django core catalog.
Revert "Fixed #20477: Allowed settings.FORMAT_MODULE_PATH to be a list of modules."

This reverts commit 950b6de16ac2f8135612f2ed5984c090dd8e4dcf.
Fixed #22652 -- Replaced UserModel.objects with UserModel._default_manager.
