[tor-commits] [tor/master] Add new warn_deprecated option to config_assign*().
commit f5dcab8072e4f8471cc0d4d8a28c79272467fb92
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date: Wed Aug 3 12:52:26 2016 -0400
Add new warn_deprecated option to config_assign*().
Also, collapse all the config_assign*() options into a flags
argument, since having two boolean arguments was already confusing.
