remove cruft from old resolver and numeric ip parsing

the old resolver code used a function __ipparse which contained the
logic for inet_addr and inet_aton, which is needed in getaddrinfo.
this was phased out in the resolver overhaul in favor of directly
using inet_aton and inet_pton as appropriate.

this commit cleans up some stuff that was left behind.
