Simplify getnameinfo (#196)

Browse source 
The getnameinfo implementation requires an address -> name lookup on the
hosts file (ie struct HostsTxt) and the previous implementation used
flags to check whether HostsTxt was sorted according to address or name,
and then re-sorted it if necessary. Now getnameinfo lookup does not
require sorting, it does a simple linear lookup, and so the related code
was simplified

See #172 for discussion.
