Client now handles a RENDEZVOUS_ESTABLISHED cell when it arrives on the
rendezvous circuit. This new function applies for both the legacy system and
prop224.

Make a single entry point for the entire HS subsystem when a client circuit
opens (every HS version).

Add a function in hs_cell.{c|h} for a client to build an INTRODUCE1 cell using
an object that contains all the needed keys to do so.
Add an entry point in hs_client.c that allows a tor client to send an
INTRODUCE1 cell on a given introduction circuit.
It includes the building of the cell, sending it and the setup of the
rendezvous circuit with the circuit identifier.
The entry point function is still unused at this commit.

This commit paves the way for the e2e circuit unittests.
Add a stub for the prop224 equivalent of rend_client_note_connection_attempt_ended().
That function was needed for tests, since the legacy function would get
called when we attach streams and our client-side tests would crash with
assert failures on rend_data.
This also introduces hs_client.[ch] to the codebase.
