adb5d5afb4 * kame/sys/netinet6/nd6.c (nd6_rtrequest): changed a condition to 
decide whether to create an empty llinfo stricter so that a user
can manually change the link-layer address of an existing neighbor
cache.

b193480908 Add extensible malloc types, adapted from FreeBSD. This turns 
malloc types into a structure, a pointer to which is passed around,
instead of an int constant.  Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.

6d8d0d63d8 sync with latest KAME in6_ifaddr/prefix/default router manipulation. 
behavior changes:
- two iocts used by ndp(8) are now obsolete (backward compat provided).
  use sysctl path instead.
- lo0 does not get ::1 automatically.  it will get ::1 when lo0 comes up.
