KNF: de-__P, bzero -> memset, bcmp -> memcmp. Remove extraneous parentheses in return statements. Cosmetic: don't open-code TAILQ_FOREACH(). Cosmetic: change types of variables to avoid oodles of casts: in in6_src.c, avoid casts by changing several route_in6 pointers to struct route pointers. Remove unnecessary casts to caddr_t elsewhere. Pave the way for eliminating address family-specific route caches: soon, struct route will not embed a sockaddr, but it will hold a reference to an external sockaddr, instead. We will set the destination sockaddr using rtcache_setdst(). (I created a stub for it, but it isn't used anywhere, yet.) rtcache_free() will free the sockaddr. I have extracted from rtcache_free() a helper subroutine, rtcache_clear(). rtcache_clear() will "forget" a cached route, but it will not forget the destination by releasing the sockaddr. I use rtcache_clear() instead of rtcache_free() in rtcache_update(), because rtcache_update() is not supposed to forget the destination. Constify: 1 Introduce const accessor for route->ro_dst, rtcache_getdst(). 2 Constify the 'dst' argument to ifnet->if_output(). This led me to constify a lot of code called by output routines. 3 Constify the sockaddr argument to protosw->pr_ctlinput. This led me to constify a lot of code called by ctlinput routines. 4 Introduce const macros for converting from a generic sockaddr to family-specific sockaddrs, e.g., sockaddr_in: satocsin6, satocsin, et cetera.
