dyoung a25eaede91 Add a source-address selection policy mechanism to the kernel.
Also, add ioctls SIOCGIFADDRPREF/SIOCSIFADDRPREF to get/set preference
numbers for addresses.  Make ifconfig(8) set/display preference
numbers.

To activate source-address selection policies in your kernel, add
'options IPSELSRC' to your kernel configuration.

Miscellaneous changes in support of source-address selection:

        1 Factor out some common code, producing rt_replace_ifa().

        2 Abbreviate a for-loop with TAILQ_FOREACH().

        3 Add the predicates on IPv4 addresses IN_LINKLOCAL() and
          IN_PRIVATE(), that are true for link-local unicast
          (169.254/16) and RFC1918 private addresses, respectively.
          Add the predicate IN_ANY_LOCAL() that is true for link-local
          unicast and multicast.

        4 Add IPv4-specific interface attach/detach routines,
          in_domifattach and in_domifdetach, which build #ifdef
          IPSELSRC.

See in_getifa(9) for a more thorough description of source-address
selection policy.
