 Replying to [comment:25 nickm]:
 > Woo, I've finished reviewing.  Looks nice!  I've made some suggestions
 on the branch.

 All pushed now.

 > In addition to the review comments, here is something I'd like to see:
 I'd like to see a unit test that makes sure that the calculated SENDME
 values match SENDME values that are calculated by a different process,
 like a python script or something. This will help us make sure that we're
 calculating the right function over the correct portions of the correct
 cells.  (I didn't see a test like that, but I could have missed it.)  What
 do you think?

 So essentially, you would like a test that makes sure the digest we
 compute and match is valid outside of Tor code? That is basically the cell
 rolling digest validation?

 > Also, this branch needs a changes file.

 I'll add it once the protover commit is done. We seems to have reached a
 consensus with `FlowCtrl` so that is what I'll go for.

 > travis seems to be failing on the streamwrap unit test. That's probably
 related to changes here.

 As discussed on IRC, #29668 should be merged upstream instead of within
 this branch.

 > there's no coverage information; I'd like to know how the coverage is on
 the tests.

 I'll get you that once I have the protover commit.
