f4768038f0 o Remove the global CcpInfo. It's now part of the datalink.
Struct bundle will have its own struct ccp in the future
  too.
o The ``set stopped'' command now requires context and doesn't
  work on the IPCP FSM.
o Check if it's time to break out of our top level loop before
  doing a select - otherwise, we'll select forever :-(
o Remove `struct link'::ccp (a temporary hack).  It turns out
  that IpStartOutput() calls link_Output() and link_Output()
  incorrectly calls StartOutput() (really modem_StartOutput)
  requiring the ccp knowledge so that it can call
  IpStartOutput()...  The end result is that the whole IP
  output queue gets dumped into the modem output queue
  and a pile of physical writes are done prematurely.  This
  makes the (original) code in main() actually work in that
  it would not bother selecting() on the tun descriptor when
  our modem queue length was 20 or greater.  Instead, we now
  make that decision based on the overall queue length.

  This will need improvement later.

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 !

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.

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).

8c07a7b2e0 Create `struct link' - the logical link from which
`struct physical' (and the future `struct logical')
are derived.

29e275cee4 o Move global/static IPCP data into IpcpInfo.
o Use INADDR_ANY and INADDR_BROADCAST instead of 0 and 0xffffffff
  for IP addresses & masks.
o Move struct compreq into ipcp.c (it's none of anyone elses
  business).
o Rename MAX_STATES to MAX_VJ_STATES.
