Convert struct proto pre_connect(), connect(), bind(), and bind_add() callback function prototypes from struct sockaddr to struct sockaddr_unspec. This does not change per-implementation use of sockaddr for passing around an arbitrarily sized sockaddr struct. Those will be addressed in future patches.
Additionally removes the no longer referenced struct sockaddr from include/net/inet_common.h. No binary changes expected.
