 For a prop224 service to extend to a rendezvous point (RP) or a client to
 extend to a introduction point (IP), we need two things to change in the
 tor code.

 1) The `extend_info_t` object needs to support a list of "extra" link
 specifiers that should be put in the `EXTEND2` cell if present. From
 proposal 224:

 {{{
    The hidden service SHOULD NOT reject any LSTYPE fields which it
    doesn't recognize; instead, it should use them verbatim in its EXTEND
    request to the rendezvous point.
 }}}

 2) The ed25519 identity link specifier (LSTYPE=03, see prop220), needs to
 be mandatory for both introduction and rendezvous points as detailed in
 prop224. So we need a way to tell the circuit subsystem that "this EXTEND2
 cell is for IP or RP so put the ed25519 id in it".
