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.

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.

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.

  o Up the verison number.
  o Don't OR MODE_AUTO for -background and -ddial.
  o Don't OR MODE_INTER when we get a diagnostic connection.
  o Allow up to 40 args per line (was 20).
  o "set ifaddr" only changes the interface in AUTO mode (with other

  o Sort command descriptions in the man page.

It would then proceed to use 16 slots and no compression
anyway.  The result was a rather unusable connection.

927145be97 Overhaul ppp:

  o Remove references to stdout/stderr (incl perror())
  o Introduce VarTerm - the interactive terminal or zero
  o Allow "set timeout" to affect current session
  o Change "set debug" to "set log"
  o Allow "set log [+|-]flag"
  o Make MSEXT and PASSWDAUTH stuff the default
  o Move all #ifdef DEBUG stuff into the code - this
    shouldn't be too much overhead.  It's now controlled
    with "set log +debug"
  o Add "set log command, debug, tun, warn, error, alert"
  o Remove cdefs.h, and assume an ansi compiler.
  o Improve all diagnostic output
  o Don't trap SIGSEGV
  o SIGHUP now terminates again (log files are controlled

  o Call CloseModem() when changing devices
  o Fix parsing of third arg of "delete"

99c02d39bc Fix many buffer overruns in the code. Specifically, disallow ExpandString
to be used to expand things beyond the size of the buffer passed in.  Also
do a general cleanup of sprintf -> snprintf as well as strcpy and strncat
safety.  Also expand some buffers to allow for the largest possible data
that might be used.

This is a 2.2 candidate.  However, it needs to be vetted on -current
since little testing has been done on this due to my lack of PPP on
this machine.

9c749ffb8b Here is a diff of /usr/src/usr.sbin/ppp against current. The diffs
add some logging functionality which I find very useful.
'set debug link' will record just link up/down and address assignments.
'set debug connect' will record the entire chat dialog
'set debug carrier' will record just chat lines including 'CARRIER'
(so that I can be sure I'm getting a 28.8 line).

There was a global change required to permit LogPrintf to take a bit
mask instead of a bit position value (to permit logging some events
on either of two flags, so that no change in 'set debug lcp' would
result from the code supporting 'link'.  Thus the diffs are rather
long for such a small change.  The man page is also touched.

Oh, and there was a slight syntax problem in route.c
