commit fd37bd0af93c8cbc66901e71a03f7cb52d57070e Author: teor teor@torproject.org Date: Mon Dec 9 16:02:12 2019 +1000

update: Rename fallback.whitelist to fallback_offer_list

The input list is a list of potential fallbacks, that relay operators have offered to have hard-coded in Tor. To avoid relay operator confusion, we should rename the list based on how we use it.

Preparation for 24839.
