These programs are no longer setuid, and now lock devices with flock,
not file locks in /var/spool/. They will no longer lock against UUCP
itself unless we modify UUCP to lock with flock, but this seems highly
unlikely to be an issue in the present day.
This means we can get rid of the suid/sgid parts of the code (which
have been removed). The program is now installed with normal permissions.
To prevent accidents, we now flock the tty line, attempting to get an
exclusive lock.

Turn it off by default -- it hardly saves any space, but it's
one of the reasons why the executable is installed setuid, and
other versions of tip/cu don't write a log file anyway. We can
add syslog support later if we ever really want this back, the
file-writing is all encapsulated in log.c.
the others (maybe "Courier", but I doubt it) we can easily enough turn
them back on.
Saves 20-30K depending on platform. Not totally insignificant, since this
often goes on install media, or very small systems.
of the old zzhack-access macros, which with the current macro definitions
would cause a cast value to be used as an lvalue, which is a gcc extension,
but _not_ what we want.
