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. </sales> 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.
