This reworks systemd-run so that in --pty mode we watch the unit state

in failed or inactive state finish right-away, but first write all
unwritten characters we can read from the master TTY device.

This makes sure that when the TTY service fails before it opens the
slave PTY device we properly notice that and exit early, so that borked
start parameters result in immediate systemd-run failure. Previously,
we'd not notice this at all, as a PTY slave that never was opened won't
result in POLLHUP events, and we'd hence simply keep reading from it
forever.

enables. However, unless --wait is specified we won#t show the final

__attribute__((fallthrough)), even as a macro, is worth the trouble. It sticks
out too much, a comment is just as good. But gcc has some very specific

likes. I don't think the extra stuff we had in those comments was adding much
