[tor-commits] [onionoo/master] Fixes for reverse DNS resolver

commit 4b05f840fc19d81d5e05f8b0b89c80473024f07a Author: Iain R. Learmonth irl@fsfe.org Date: Tue Aug 14 12:51:40 2018 +0100

Fixes for reverse DNS resolver

* SortedSets are used in place of Lists to ensure deterministic ordering of looked up names * The NodeStatus serialization is extended to include verified and unverified host names * The existing host name field in NodeStatus serializations is removed and a placeholder inserted * The last reverse DNS lookup time is now only updated on successful lookups * The host name field is removed from summary and details documents * Tests are updated to use SortedSets in place of Lists
