Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs. The SYSCTL_NODE macro defines a list that stores all child-elements of that node. If there's no SYSCTL_DECL macro anywhere else, there's no reason why it shouldn't be static.

r238002 by tuexen@: Remove dead code (on FreeBSD) as suggested by glebius@. r238016: Remove route caching from IP multicast routing code. There is no reason to do that, and also, cached route never got unreferenced, which meant a reference leak. Reviewed by: bms r238092: When ip_output()/ip6_output() is supplied a struct route *ro argument, it skips FLOWTABLE lookup. However, the non-NULL ro has dual meaning here: it may be supplied to provide route, and it may be supplied to store and return to caller the route that ip_output()/ip6_output() finds. In the latter case skipping FLOWTABLE lookup is pessimisation. The difference between struct route filled by FLOWTABLE and filled by rtalloc() family is that the former doesn't hold a reference on its rtentry. Reference is hold by flow entry, and it is about to be released in future. Thus, route filled by FLOWTABLE shouldn't be passed to RTFREE() macro. - Introduce new flag for struct route/route_in6, that marks route not holding a reference on rtentry. - Introduce new macro RO_RTFREE() that cleans up a struct route depending on its kind. - All callers to ip_output()/ip6_output() that do supply non-NULL but empty route should use RO_RTFREE() to free results of lookup. - ip_output()/ip6_output() now do FLOWTABLE lookup always when ro->ro_rt == NULL.
