Trybots are unhappy because it can't cleanly apply this patch without
https://codereview.chromium.org/1336143002/.

I have tests for token binding where I want token binding enabled, but channel
id disabled on the server. (This is because whether or not channel id is enabled
affects how the client loads its channel id/token binding key.)

Clearly I should ask you to update to tlslite 0.4.9 and take over maintaining
third_party/tlslite for me! :-D

(Not actually serious. Updating tlslite is a huge pain, and I'm not sure 0.4.9
actually gets us anything useful. We'd maybe get to drop the FALLBACK_SCSV
patch, but that's it.)
