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
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').
generate the data to transfer.
o Transfer uucp lock ownership for the transferred device.
o Don't assume we know the correct values of dev_is_modem and
mbits after the transfer.
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.
