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. -Erik
