Comment (by dgoulet):

 New branch is here: `ticket30382_043_01`.

 So far is implements there extended error codes:

 {{{
 X'F0' Onion Service Descriptor Can Not be Found
 X'F1' Onion Service Descriptor Is Invalid
 X'F4' Onion Service Missing Client Authorization
 X'F5' Onion Service Wrong Client Authorization
 }}}

 The two missing ones are the intro failure and RP failure which are _very_
 _very_ tricky to be honest.

 For now, the SOCKS reply is not send back before the rendezvous has opened
 the stream so basically like if there is no optimistic data.
