I made the change to improve consistency between lib/libc/string and
sys/libkern, which is what Bruce commented on some time ago. I don't
have a personal preference for 0 or '\0' but definitely believe that
if we have multiple, similar copies of a function they ought to avoid
gratuitous differences. (I'm happy to change both trees to 0 if that's
preferred.)
