Merge master (0.19.1, TARIFF-24) into OPT-27 so the work has the weather hold to build on

release/1.0 (4a1f6cc) does not yet contain TARIFF-24 (PR #212, merged into
hotfix-0.19.1, then master 2932f3a). OPT-27 is about that code (the 1.5x
no-weather widening, _wx_track/weather_held), so it needs it. This is the
planned master -> release/1.0 merge's content, taken at 2932f3a; clean merge,
no conflicts.
