[tor-commits] [tor/master] prop224: Add a init/free_all function for the whole subsystem



commit 765ed5dac160b28fb658560e8f39d1d7ab3d1c75

    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.
