- Fix log message format string.
- Do extra circuit purpose check.
- wipe memory in a clear function
- Make sure we don't double add intro points in our list
- Make sure we don't double close intro circuits.
- s/tt_u64_op/tt_i64_op/
Turns out that introduction points don't care about the INTRODUCE2 cell
format as long as the top field is LEGACY_KEY_ID as expected. So let's
use a single INTRODUCE format regardless of the introduction point being
legacy or not.
This also removes the polymorphic void* situation.

Make this function public so we can use it both in hs_circuit.c and
hs_service.c to avoid code duplication.

This introduces a callback to relaunch a service rendezvous circuit when a
previous one failed to build or expired.
It unifies the legacy function rend_service_relaunch_rendezvous() with one for
specific to prop224. There is now only one entry point for that which is
hs_circ_retry_service_rendezvous_point() supporting both legacy and prop224
circuits.

Add the entry point from the circuit subsystem of "circuit has opened" which
is for all type of hidden service circuits. For the introduction point, this
commit actually adds the support for handling those circuits when opened and
sending ESTABLISH_INTRO on a circuit.
Rendevzou point circuit aren't supported yet at this commit.

This commit adds most of the work of #21859. It introduces hs_circuit.c
functions that can handle the setup of e2e circuits for prop224 hidden
services, and also for legacy hidden service clients. Entry points are:
prop224 circuits: hs_circuit_setup_e2e_rend_circ()
legacy client-side circuits: hs_circuit_setup_e2e_rend_circ_legacy_client()
This commit swaps the old rendclient code to use the new API.
I didn't try to accomodate the legacy service-side code in this API, since
that's too tangled up and it would mess up the new API considerably IMO (all
this service_pending_final_cpath_ref stuff is complicated and I didn't want to
change it).
