prop224: Add a init/free_all function for the whole subsystem

Introduces hs_init() located in hs_common.c which initialize the entire HS v3
subsystem. This is done _prior_ to the options being loaded because we need to
allocate global data structure before we load the configuration.

The hs_free_all() is added to release everything from tor_free_all().

Note that both functions do NOT handle v2 service subsystem but does handle
the common interface that both v2 and v3 needs such as the cache and
circuitmap.
