Introduce ID0 logging. Stay as the invoking uid as much as possible. Execution as a normal user is still forbidden for now, so these changes are pretty ineffective. The next commit will implement the modifications suggested on -hackers a number of days ago.

Make -DNOSUID (or -DPPP_NOSUID) possible to build ppp without SUID capabilities.

#ifndef NOSUID
Port ppp(8) to utmpx. A nice thing about utmpx is that it makes it very easy to log sessions that don't use TTYs. This is because the file is not indexed by TTY slots anymore. Silence from: brian

MFMP: Make ppp multilink capable. See the file README.changes, and re-read the man page.

struct sockaddr_un;
MFMP: Allow 8 character login names. Do the login()/logwtmp()/logout() as id 0.

Write to the routing socket as uid 0. It's not good enough to just open it as uid 0 under OpenBSD.

o If there's a session leader left running for a descriptor that we're now closing, manually HUP that session leader so that the tty is fully released. o Always restart our carrier detect timer in the receiving process if it was running in the sending process (as we now *always* pass the descriptor). o Tweak argv when we go into pause() mode to keep our session so that ps can see what's going on (without checking for a `pause' state in `ps -l').
