Brian Somers 3b0f8d2ed6 o Move struct lcp and struct ccp into struct link.
o Remove bundle2lcp(), bundle2ccp() and bundle2link().
  They're too resource-hungry and we have `owner pointers'
  to do their job.
o Make our FSM understand LCPs that are always ST_OPENED
  (with a minimum code that != 1).
o Send FSM code rejects for invalid codes.
o Make our bundle fsm_parent deal with multiple links.
o Make timer diagnostics pretty and allow access via ~t
  in `term' mode (not just when logging debug) and
  `show timers'.  Only show timers every second in debug
  mode, otherwise we get too many diagnostics to be useful
  (we probably still do).  Also, don't restrict ~m in term
  mode to depend on debug logging.
o Rationalise our bundles' phases.
o Create struct mp (multilink protocol).  This is both an
  NCP and a type of struct link.  It feeds off other NCPs
  for output, passing fragmented packets into the queues
  of available datalinks.  It also gets PROTO_MP input,
  reassembles the fragments into ppp frames, and passes
  them back to the HDLC layer that the fragments were passed
  from.
  ** It's not yet possible to enter multilink mode :-( **
o Add `set weight' (requires context) for deciding on a links
  weighting in multilink mode.  Weighting is simplistic (and
  probably badly implemented) for now.
o Remove the function pointers in struct link.  They ended up
  only applying to physical links.
o Configure our tun device with an MTU equal to the MRU from
  struct mp's LCP and a speed equal to the sum of our link
  speeds.
o `show {lcp,ccp,proto}' and `set deflate' now have optional
  context and use ChooseLink() to decide on which `struct link'
  to use.  This allows behaviour as before when in non-multilink
  mode, and allows access to the MP logical link in multilink
  mode.
o Ignore reconnect and redial values when in -direct mode and
  when cleaning up.  Always redial when in -ddial or -dedicated
  mode (unless cleaning up).
o Tell our links to `staydown' when we close them due to a signal.
o Remove remaining `#ifdef SIGALRM's (ppp doesn't function without
  alarms).
o Don't bother strdup()ing our physical link name.
o Various other cosmetic changes.
