a611cad61d o Don't immediately reply to the first LQR thinking
it's a duplicate ('cos it compares with our initial
  values).
o Move the LCP into struct datalink.

879ed6fa82 De-staticise LQR information
Increment OutPackets for any packet - not just LQRs

MFC:
  o Fix a few comment typos.
  o Fix ``set timeout'' usage message and documentation.
  o Change ifOutPackets, ifOutOctets and ifOutLQRs to `u_int32_t's
    so that they wrap correctly.
  o Put the LQR in network byte order using the correct struct size
    (sizeof u_int32_t, not sizeof u_long).
  o Wrap LQR ECHO counters correctly.
  o Don't increment OutLQR count if the last LQR hasn't been replied
    to.
  o Initialise last received LQR in StartLqm.
  o Don't start the LQR timer if we're `disabled' and `accepted'.
  o Generate LQR responses when both sides are using a timer and
    we're not going to send our next LQR before the peers max timeout.

d2fd8d772f Force IPCP back to initial in bundle_Close().
Add a few un-necessary includes to make us build under
2.2.5.  These'll go when the code is cleaned up at the
end.

e2ebb036fd Do authentication at the datalink level, not the bundle level.
The bundle doesn't get a LayerUp 'till we're authenticated.

Introduce DATALINK_LCP and DATALINK_AUTH phases.

6d6667755e Create struct fsm_parent. FSMs are created with one of these,
and the FSM passes subsequent events to them.

63258dccc5 o Create `struct hdlc' - a part of struct physical.
o Move our LCP report timer into struct hdlc - it's really
  a hdlc timer (fcs errors etc).
o Make `show hdlc' require context and make the output more
  friendly.
o Remove all non-const globals from hdlc.c
o Output peer-rejected protocols by name - not just ones
  that we reject.

3006ec67fe Create struct datalink.
This is a type of physical link that can chat and talk
LCP & CCP.  A bundle contains a list of these (only one
in the list for the moment).

The datalink is a type of descriptor, and dials, enters
LCP (& does CCP), kicks the bundle when its FSMs do
something interesting and does the hangup chat script
on the way down.  It also handles redials and reconnects.

There are lots of loose ends, and probably lots of bugs,
but the data structures are getting there !

42d4d39668 o Introduce struct descriptor.

  main loop.

455aabc3f8 o Hook the FSMs into our bundle.
o The FSM layering is now more sane.
o Move a lot of the NCP stuff into our ipcpstate rather than having it
  in the bundle, including control of the configured IP addresses.  We
  don't need hacks like the global `linkup' variable any more as the
  FSM decides when our ppp.link* files get run.  This is going to eventually
  be configurable based on FSM events anyway.
o Fix a few inconsistencies when both sides require authentication.
o We now have "Ppp..." and "PPp" prompts, reflecting authentication
  and network phase.  We don't print loads of spurious prompts as we
  change phases any more.
o Our phase is part of the bundle now.
o Fix a bug where the FSM wasn't calling LayerFinish.
o Close the FSM down correctly with a signal rather than slamming it
  down as if the line was dropped (the undocumented ``down'' command
  is still available though).
o Remove the forgotten `tunno' variable and fix references to it.

6140ba1177 Create struct async' and make it part of struct physical'.
This structure contains the asynchronous state of the physical
link.
Unfortunately, just about every .h file is included in every .c
file now.  Fixing this can be one of the last jobs.

7a6f872047 Create `struct bundle' - the top level control structure.
This structure will eventually contain a list of NCPs (currently
only IPCP is supported) and a list of physical `struct link's.
It will also derive from a struct link itself.
Make ModemTimeout() static - it's way to dangerous to be called
from outside !
Bump version to 1.9.  Our first MP release should be 2.0.

7308ec6890 Move the global FSMs into their relevent structures.
IPCP, CCP and LCP are now just derived FSMs.
Comment each of the FSM implementations so that we can
tell what's going on.
Revise the state transitions so that CCP and IPCP actually
send terminate REQs when appropriate.

The OS & IPCP layers are still like spagetti (next job).

49b239e0d2 Allow an optional delay when specifying "set openmode active".
The delay defaults to 1 sec (as it always has) unless we've done
a ~p in interactive mode or we've actually detected a HDLC frame.
This is now cleanly implemented (via async timers) so that it is
possible for LCP to come up despite the delay if an LCP REQ is
received.

This will hopefully solve situations with slow servers or slirp
scenarios (where ECHO is left on the port for a second or so before
the peer enters packet mode).

Also, ~p in interactive mode no longer changes the value of the default
openmode delay and -dedicated mode enters packet mode in the right state
according to the value of openmode.

b0624e7fc6 Fix PAP, CHAP & LQR req (I broke the byte ordering when

suggesting PAP, be friendly and REQ PAP the next time.

6a6b4bbb08 Abstract data read from and written to the tun device,
allowing for a possible header on the front of all packets.
In OpenBSD, there's a structure containing the address
family here.
If we're building under OpenBSD, set up the ``flags'' part
of struct tuninfo (not there under FreeBSD) so that we config
the interface as POINTOPOINT.
Prefix prototypes with ``extern'' in os.c for consistency.

These changes are cosmetic under FreeBSD, but allow ppp to
build & work under OpenBSD (bar the srandomdev() stuff,
the inclusing of <net/if_var.h> and some Makefile symantecs).

30bbbd3edd Initialise LCP, IPCP and CCP as soon as LCP is down.
Without this, in -auto mode, we stay in ST_STOPPING
and never check our dial filters to see if it's time
to bring the line up again.

This may make "set stopped" redundant.

e70c96ab58 Change things around a bit when bringing down the layers.
o LcpLayerDown() no longer does a NewPhase(PHASE_TERMINATE).
  Instead, it's done in LcpLayerFinish().  LayerFinish() gets
  called by the FSM after the LCP FSM goes through the Stopping
  and Stopped states.

o -direct and -background mode exit at PHASE_TERMINATE, not
  PHASE_DEAD.

The result is that LCP, CCP & IPCP are brought down cleanly on both
sides of the link (not just our side).  Killing ppp rather than just
closing it still makes it get out after the LCP SendTerminateReq().
I'll have a look at that soon.  We're probably not actually sending
the REQ :-(
