Import version 1.5 of ppp.

<sales>
This is a user-level ppp implementation that uses the
tun driver.  It was originally created by a Japanese
ISP.  It's now piled with features.  Check the man pages
for details.

The sources are identical to the ones in FreeBSD, except
for the Makefile.

IP aliasing (NAT) is disabled, and can be enabled by simply
doing a ``make install'' of libalias, then rebuilding
ppp.  I'll create libalias as a port soon.
