netsock2: ast_addressfamily_to_sockaddrsize and ast_sockaddr_from_sockaddr.
ast_addressfamily_to_sockaddrize will determine the size that's required, and ast_sockaddr_from_sockaddr then wraps this new function and ast_sockaddr_copy_sockaddr to copy arbitrary sockaddr's (without knowing the address family) into the ast_sockaddr structure.
