dca105d588 prop224: Register RP circuit when it opens
Only register the RP circuit when it opens and not when we send the INTRODUCE1
cell else, when re-extending to a new IP, we would register the same RP
circuit with the same cookie twice leading to the circuit being closed.

f02868bb53 hs: Add service-side circuitmap API.
Now we have separate getters and setters for service-side and relay-side. I
took this approach over adding arguments to the already existing methods to
have more explicit type-checking, and also because some functions would grow
too large and dirty.

This commit also fixes every callsite to use the new function names which
modifies the legacy HS (v2) and the prop224 (v3) code.

2b9abbef2e prop224 prepwork: Introduce HS circuitmap subsystem.
The HS circuitmap is a hash table that maps introduction and rendezvous
tokens to specific circuits such that given a token it's easy to find
the corresponding circuit. It supports rend circuits and v2/v3 intro
circuits.

It will be used by the prop224 ESTABLISH_INTRO code to register and
lookup v3 introduction circuits.

The next commit after this removes the old code and fixes the unittests.
Please consult both commits while reviewing functionality differences
between the old and new code. Let me know if you want this rebased
differently :)

WRT architectural differences, this commit removes the rendinfo pointer
from or_circuit_t. It then adds an hs_token_t pointer and a hashtable
node for the HS circuitmap. IIUC, this adds another pointer to the
weight of or_circuit_t. Let me know if you don't like this, or if you
have suggestions on improving it.
