This makes the REPLICA= field optional for the control port event. A v2
service will always pass it and v3 is ignored.

A new v3 specific function has been added named
control_event_hsv3_descriptor_failed().
The HS v3 subsystem now uses it.

This changes the control_event_hs_descriptor_requested() call to add the hsdir
index optional value. v2 passes NULL all the time.
This commit creates hs_control.{c|h} that contains wrappers for the HS
subsystem to interact with the control port subsystem.
The descriptor REQUESTED event is implemented following proposal 284 extension
for v3.
