*after* shuffling fragments from the IP queue into the
individual link queues.
This fixes a latency problem pointed out by: Bruce Evans <bde@zeta.org.au>
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').
in `set mode', `allow modes', on the command line and when
outputting mode names. The strings are matched so that only
enough characters to uniquely identify the string are required,
so you can now
ppp -a mylabel (for auto mode)
ppp -b mylabel (for background mode)
ppp -dd mylabel (for direct dial mode)
etc.
o Make -ddial dial when specified on the command line (oops).

of supporting architectures with different device names.
o Close /dev/tunX when destroying the bundle.
o Don't forget to close the parent end of the pipe in the child
process when exec'ing a program from a chat script.
o If we close our controlling terminal, ditch the current session
with it, allowing getty(8) (or whatever) to regain control.
o After transferring our controlling terminal descriptor to another
ppp instance, we now fork a new ppp to continue where we left off,
transferring ownership of all uucp locks and the /var/run/tunX.pid
file. Meanwhile the parent closes all file descriptors, defaults
all signals and does a pause() to wait for a HUP after the
transferred descriptor is finally closed.
We don't run /bin/cat any more (again!).

TODO: It seems clocal devices need their pause()d session leader
to be given a manual HUP, as closing the last open descriptor
doesn't do the job.
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.
transferring session rights with them. Instead, create two
`/bin/cat' processes. A new child is spawned and disassociated from
the terminal and the parent, which continues with the rest of the ppp
process. Meanwhile, the parent spawns another child, and both the
parent and child exec the `/bin/cat' commands with the appropriate
descriptors. This way, the session is owned by the parent, and the
tty is held open.
o Close LCPs that have done a TLF and are now in ST_STOPPED before
calling Down. This prevents them from trying to come back up again
after the peer has shut them down (it seems a bit strange that the
rfc says that a Down in ST_STOPPED will cause a TLS etc).
o Don't try to set the physical link name pointer when we're receiving
and renaming a datalink. The physical hasn't been created yet, and as
it happens, the garbage physical pointer happens to be the value of another
physical - so we're pointing that other physical name at ourselves.
yeuck.
o Re-arrange the order of things in main (DoLoop()). We now handle
signals only after the select and not before the UpdateSet. It's
possible that either a signal (FSM timeout) or a descriptor_Read()
brings a link down, after which we'd better tidy up any dead direct
and 1off descriptors before calling UpdateSet() again.
o Mention when we detect a PPP packet when we see one before the link
is up (then start LCP as before).
It's now dealt with by the `server' object. This simplifies
things as we only have one list of prompt descriptors and
the log_ routines check prompt::logactive to determine
whether it should be used for output.
o Include the MP socket UpdateSet() result in bundle::UpdateSet().
o Don't select on the tun device unless we're in NETWORK
phase or AUTO mode.
o Stop the idle timer when we go to DEAD phase. We may
have transferred a link and not had a chance to kill
it.
o Don't fail when trying to unlink our transferred datalink
from our descriptor lists just before the transfer.
o Add our link descriptor to the write set if we got a short
write the last time (physical::out is set).
o Log the connection source address when a connection is closed.
o Remove descriptor::next field. Descriptor lists are not required
any more.
incoming fragments when a link goes down.
o Don't use the minimum sequence numbers of links that aren't open.
o Understand sequence number wrapping when determining the minimum
sequence number.
o Add & adjust a few comments.
