Instead of using SCRIPT_NAME / FORCE_SCRIPT_NAME, PATH_INFO
and their associated issues, update urls.py to add the subpath
to all routes. This allows us to get rid of several hacks:
* the uwsgi.ini magic which parses SITE_ROOT, sets SCRIPT_NAME
and fixes PATH_INFO
* set_script_prefix() in sendalerts
* chopping the subpath off an URL in hc.accounts.views._allow_redirect
The idea comes from @apollo13
in https://code.djangoproject.com/ticket/35985#comment:5

* set post-buffering (buffer for POST data) to 16192
* add auto-procname for friendlier process names
* add strict, uwsgi won't start if uwsgi.ini contains invalid options
