Comment (by asn):

 Also, in `cell_introduce1.trunnel`:

 - I don't see anywhere the `CLIENT_PK` or `MAC` fields of the `INTRODUCE1`
 cell as specified in section `[NTOR-WITH-EXTRA-DATA]`. Also, if we have a
 MAC we also need the appropriate `ptr`s.

 - `s/Link specificer/Link specifier/`

 - Also can we replace the magic number of `rend_cookie[20]` with some sort
 of name? The actual code is using `REND_COOKIE_LEN`, but I guess we can't
 reuse that. No worries if there is no good solution here, just leave it as
 is.
