7551d83c35 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

ee9763124d Merge the NETGRAPH branch into HEAD. tty devices now use netgraph's line
discipline to do the async escaping, but no other benefits are available yet.

Change ``ifdef HAVE_DES'' to ``ifndef NODES'' for consistency.

Make the Makefile a little more sane WRT RELEASE_CRUNCH.

659744dd68 Rewrite the link descriptor transfer code in MP mode.
Previously, ppp attempted to bind() to a local domain tcp socket
based on the peer authname & enddisc.  If it succeeded, it listen()ed
and became MP server.  If it failed, it connect()ed and became MP
client.  The server then select()ed on the descriptor, accept()ed
it and wrote its pid to it then read the link data & link file descriptor,
and finally sent an ack (``!'').  The client would read() the server
pid, transfer the link lock to that pid, send the link data & descriptor
and read the ack.  It would then close the descriptor and clean up.

There was a race between the bind() and listen() where someone could
attempt to connect() and fail.

This change removes the race.  Now ppp makes the RCVBUF big enough on a
socket descriptor and attempts to bind() to a local domain *udp* socket
(same name as before).  If it succeeds, it becomes MP server.  If it
fails, it sets the SNDBUF and connect()s, becoming MP client.  The server
select()s on the descriptor and recvmsg()s the message, insisting on at
least two descriptors (plus the link data).  It uses the second descriptor
to write() its pid then read()s an ack (``!'').  The client creates a
socketpair() and sendmsg()s the link data, link descriptor and one of
the socketpair descriptors.  It then read()s the server pid from the
other socketpair descriptor, transfers any locks and write()s an ack.

Now, there can be no race, and a connect() failure indicates a stale
socket file.

This also fixes MP ppp over ethernet, where the struct msghdr was being
misconstructed when transferring the control socket descriptor.

Also, if we fail to send the link, don't hang around in a ``session
owner'' state, just do the setsid() and fork() if it's required to
disown a tty.

faf44b90cf Introduce ``set logout''; another chat script. This is in preparation
for the abstraction of ``set dial'' and ``set hangup''.

8229df47c3 Add ISDN support via isdnd & i4b. This requires version
0.81.1 of the i4b code - namely support of the I4B_VR_REQ
ioctl via the i4brbchX device.

Ppp controls the phone number, but idle timers and
SYNC/RAW decisions are still made by isdnd (in isdnd.rc).

This involves a new datalink state machine phase.  The
``wait for carrier'' phase happens after dialing but
before logging in.  The whole dial state should really
be abstracted so that each device type can deal with it
in its own way (thinking about PPPoE) - but that'll have
to wait.

The ``set cd'' symantics remain the same for tty devices,
but we now delay until we either get CD or timeout waiting
(at which time we drop the link if we require CD).

For i4b devices we always insist on carrier.

Thanks to hm@ for his help, and especially for pointing out
that I *don't* need to re-implement isdnd (that was a huge
waste of time !) :-]

4435d086fa Decouple pap & chap output routines from the corresponding
input routines and take advantage of the new init/continue
interface in libradius.  This allows a timely response on
other links in an MP setup while RADIUS requests are in
progress as well as the ability to handle other data from
the peer in parallel.  It should also make the future addition
of PAM support trivial.

While I'm in there, validate pap & chap header IDs if
``idcheck'' is enabled (the default) for other FSM packet
types.

NOTE: This involved integrating the generation of chap
      challenges and the validation of chap responses
      (and commenting what's going on in those routines).
      I currently have no way of testing ppps ability
      to respond to M$Chap CHALLENGEs correctly, so if
      someone could do the honours, it'd be much
      appreciated (it *looks* ok!).

f9ee8808e7 o Support callback types NONE, E.164, AUTH and CBCP.
(see the new ``set callback'' and ``set cbcp'' commands)
o Add a ``cbcp'' log level and mbuf type.
o Don't dump core when \T is given in ``set login'' or
  ``set hangup''.
o Allow ``*'' and blanks as placeholders in ppp.secret and
  allow a fifth field for specifying auth/cbcp dialback
  parameters.
o Remove a few extraneous #includes
o Define the default number of REQs (restart counter) in defs.h
  rather than hardcoding ``5'' all over the place.
o Fix a few man page inconsistencies.

4ea5840027 Make `close lcp' just close the LCP layer and not hangup. This is
useful for slirp users that wish to get their shell back after the
ppp session.  `close' with no args still hangs up as expected.

o Transfer uucp lock ownership for the transferred device.
o Don't assume we know the correct values of dev_is_modem and
  mbits after the transfer.
