New function named hs_cell_introduce1_data_clear() is introduced to clear off
an hs_cell_introduce1_data_t object.

The client is now able to handle an INTRODUCE_ACK cell and do the appropriate
actions.
An intro point failure cache is missing and a way to close all intro point
that were launched in parallel. Some notes are in the comment for that.

Add a function to parse an INTRODUCE_ACK cell in hs_cell.c. Furthermore, add
an enum that lists all possible expected status code.

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.

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.

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.
