Comment:

 See my PR:
 * master: https://github.com/torproject/tor/pull/1863

 The unit tests cover the two major cases:
 * dual-stack EXTEND2 cells
 * IPv6-only EXTEND2 cells

 The tests also cover cell parsing and cell encoding.

 They don't cover the edge cases of all-zero IP addresses or ports. I'm not
 particularly worried about those cases.
