Merged requested to merge nickm/tor:bug40645_045 into maint-0.4.5
crash with an assertion failure if
low_timeout was greater than
high_timeout. That wasn't possible in practice because of checks
channelpadding_update_padding_for_channel, but it's better not
to have a function whose correctness is this tricky to prove.
Fixes #40645 (closed). Bugfix on 0.3.1.1-alpha.
I've made this patch against 0.4.5 in case we decide to Backport.
