I have committed this.

I have removed the inet header refactoring that you had.  That wasn't 
necessary, since pg_inet_net_ntop() can use the normal AF_INET* 
constants.  The PGSQL_AF_INET* constants are only for the internal 
storage of the inet/cidr types.

I have added a configure test for inet_pton().  We can check in the 
build farm if it turns out to be necessary.
