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.

(say SIGUSR1) so that a machine with PCCARDs has a chance.

o Move our prompt descriptor list outside of the bundle.
It's now dealt with by the `server' object. This simplifies
things as we only have one list of prompt descriptors and
the log_ routines check prompt::logactive to determine
whether it should be used for output.
o Include the MP socket UpdateSet() result in bundle::UpdateSet().
o Don't select on the tun device unless we're in NETWORK
phase or AUTO mode.
o Stop the idle timer when we go to DEAD phase. We may
have transferred a link and not had a chance to kill
it.
o Don't fail when trying to unlink our transferred datalink
from our descriptor lists just before the transfer.
o Add our link descriptor to the write set if we got a short
write the last time (physical::out is set).
o Log the connection source address when a connection is closed.
o Remove descriptor::next field. Descriptor lists are not required
any more.

identified as being wrong as a result.

o Remove the `mode' global - it's now per physical device.
o Shuffle things that live at the datalink level into
``show link'' rather than ``show modem''.
o Make both ``show'' commands prettier and more consistent,
and display carrier status, link type and our name in
``show modem''.
o Show redial and reconnect information in ``show link''
and remove ``show redial'' and ``show reconnect''.
o Down the correct link in bundle_LinkLost().
o Remove stale -direct and -background links at the end
of our main loop, not when we know they're going. This
prevents unexpected pointer-invalidations...
o If we ``set server'' with the same values twice, notice
and don't moan about failure.
o Record dial script despite our link mode. The mode may
be changed later (next mod) :-) We never run scripts
in -direct and -dedicated modes.
o Make ``set server none'' functional again.
o Correct datalink state array so that we don't report an
``unknown'' state.
o Pass struct ipcp to IpcpCleanInterface, not struct fsm.
o Create TUN_PREFIX define rather than hard-coding in main.c
o prompt_TtyInit now handles a NULL prompt for -direct mode
rather than having to create one then destroy it uncleanly.
o Mention our mode in the "PPP Started" LogPHASE message.
o Bring all auto links up when we have something to send.
o Remove some redundant Physical_*() functions.
o Show which connection is running a command when logging
commands.
o Initialise throughput uptime correctly.

SIGTTIN or SIGTTOU, we just disable use of the prompt
for the controlling terminal (and put a ^Z next to it

Unfortunately, we need to enable a timer to ``poll''
for the terminal having us as the controlling pgrp
when a user does a ``bg''. If anyone knows how to
do this better - please speak up (is there any
indication to the process group leader when it's
ctrling terminal gets tcsetpgrp()'d back ?)....

Deglobalise `struct prompt':
o Our diagnostic socket has its password set in the `set socket'
line only (not in ppp.secret).
o Passwords are per server socket (*VarAuthKey are gone)
o Authority is per prompt (VarLocalAuth is gone).
o Local logging is per prompt.
o Add a `show who' command to see who's connected. No identd
routine - just a `where the connection came from' display.
o SIGUSR1 is disabled for now - we have no way of choosing a
password for the socket created :-(

Prompts are attached as a list of `struct descriptor's in
struct bundle, and serviced under the bundles descriptor
service routines. Ultimately, everything should be done
like this.

Cosmetic:
o alphabeticalise SRCS in Makefile.
o Add a few comments in command.h

TODO: Start checking that we don't overflow the descriptor sets
in select() now that we can have any number of descriptors.

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 !
