#3733: Tor should abandon rendezvous circuits that cause a client request to time
out

Priority: Medium | Milestone: Tor:
| unspecified

Changes (by dgoulet):
* parent: #17242 => #23300
Comment:
Switching parent so we can close #17242.
(Only speaking v3):
`CIRCUIT_PURPOSE_C_ESTABLISH_REND` is handled properly, if it's open and
passes its cutoff, it will get expired.
`CIRCUIT_PURPOSE_C_REND_READY` is '''not''' handled properly I believe. An
intro and rend circuit are linked together when the client sends an
INTRODUCE1 cell that is when the `rendezvous_cookie` is copied from the
rend circuit `hs_ident` to the intro circuit one. Once they are linked
together, the rend circuit is closed by any error on the intro circuit
side.
`CIRCUIT_PURPOSE_C_REND_READY_INTRO_ACKED` is handled properly, same exact
cutoff check as the establish rend purpose but then it is flagged has
`hs_circ_has_timed_out`.
So all in all, we need to handle correctly the rend ready purpose for a v3
service and we should have this fixed.
