Modified Files:
        src/sys/net: if.c if.h
        src/sys/netinet6: icmp6.c in6_pcb.c in6_src.c ip6_output.c ip6_var.h
            nd6_nbr.c raw_ip6.c udp6_output.c

Log Message:
Make sure returning ifp from in6_select* functions psref-ed

To this end, callers need to pass struct psref to the functions
and the fuctions acquire a reference of ifp with it. In some cases,
we can simply use if_get_byindex, however, in other cases
(say rt->rt_ifp and ia->ifa_ifp), we have no MP-safe way for now.
In order to take a reference anyway we use non MP-safe function
if_acquire_NOMPSAFE for the latter cases. They should be fixed in
the future somehow.
