Django 1.11 upgrade (cover letter only)

Django 1.8 has gone out of support upstream, so here are the necessary changes to upgrade to Django 1.11.x (the next LTS release). Along the way I switched the Bulk Change feature to use OE's code for patching recipes, since that part was broken by the upgrade (and possibly broken otherwise).

I've posted the cover letter only to avoid too much noise for folks that aren't interested - see the branch for details.

The following changes since commit 611c96883c35240d3c291951146154d828745774:

requirements.txt: use the most recent Django 1.8 version (2018-03-26 08:29:27 +1300)

are available in the Git repository at:
