/*! \file net.h
* This module is responsible for defining the following basic networking
* types:
*
*\li struct in_addr
*\li struct in6_addr
*\li struct sockaddr
*\li struct sockaddr_in
*\li 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.
