Comment:

 I'll put this into needs_review now. Here's a commit that bumps the
 version of webrtc and removes the need for the patch:
 https://github.com/cohosh/tor-browser-
 build/commit/873685ba2a4756176bf2a680563f09d297cd3a50

 And the rebased pion branch of snowflake:
 https://github.com/cohosh/snowflake/compare/pion

 While being able to
 [https://github.com/cohosh/snowflake/commit/ef59d09f7cef7970e34efa18da0612e38f8f5002
 being able to use the pion logs] would be nice, we need Go 1.13 to do it
 nicely, and we haven't yet bumped the version for Tor Browser builds. I
 would like to cherry-pick
 [https://github.com/cohosh/snowflake/commit/f370a4f296de432c392c6fc2f204fd3877a60429
 adding locks to safelog] though.

 Note also that starting with
 [https://github.com/pion/webrtc/releases/tag/v2.1.4 v2.1.4], pion/webrtc
 is moving to Go 1.13. I'm not sure yet if it can still be built with Go
 1.12.
