/*
 * Basic Networking Types
 *
 * This module is responsible for defining the following basic networking
 * types:
 *
 *		struct in_addr
 *		struct in6_addr
 *		struct sockaddr
 *		struct sockaddr_in
 *		struct sockaddr_in6
 *
 * It ensures that the AF_ and PF_ macros are defined.
 *
 * It declares ntoh[sl]() and hton[sl]().
 *
 * It declares lwres_net_aton(), lwres_net_ntop(), and lwres_net_pton().
 *
 * It ensures that INADDR_LOOPBACK, INADDR_ANY and IN6ADDR_ANY_INIT
 * are defined.
