Add RO_MSGFILTER socket option to PF_ROUTE to filter out un-wanted route(4) messages. Inspired by the ROUTE_MSGFILTER equivalent in OpenBSD, but with an API which allows the full range of potential message types.

Fix race condition on the rawcb list shared by rtsock and keysock keysock now protects itself by its own mutex, which means that the rawcb list is protected by two different mutexes (keysock's one and softnet_lock for rtsock), of course it's useless. Fix the situation by having a discrete rawcb list for each.

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.

Eliminate struct protosw::pr_output. You can't use this unless you know what it is a priori: the formal prototype is variadic, and the different instances (e.g., ip_output, route_output) have different real prototypes. Convert the only user of it, raw_send in net/raw_cb.c, to take an explicit callback argument. Convert the only instances of it, route_output and key_output, to such explicit callbacks for raw_send. Use assertions to make sure the conversion to explicit callbacks is warranted. Discussed on tech-net with no objections: https://mail-index.netbsd.org/tech-net/2016/01/16/msg005484.html
