  Log:
  o Don't try to transfer tty device descriptors as there's no way of
    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).
