* Basic Networking Types

* This module is responsible for defining the following basic networking

* 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.
