Add in libutil, based on Cory Visi's variant of Michael Shmulevich's libutil

port.  I have reworked the code quite a bit so that the stuff that is supposed
to be in libc is in libc, and I added a bunch of missing stuff so the libutil
interface matches that of glibc's libutil.  The only caveat is that
libutil/login.c is currently a stub.
