o Create a new ``timer'' log level. This lets us ``set
log debug'' without filling our filesystem/screen with
junk that we don't really want to see.
o change PHYS_STDIN to PHYS_DIRECT - we can handle incoming
connections that aren't on STDIN_FILENO now.
o Allow return values from our FSM LayerUp functions. If
LayerUp() fails, the FSM does an immediate FsmDown() without
calling the fsm_parent's Layer{Up,Down} functions.
o Clear the close-on-exec flag of file descriptor 3 when executing
chat programs so that our documented ability to communicate with
/dev/tty via that descriptor works. Also document it as
descriptor 3, not 4 :-O
o Allow a ``rm'' command as an alias for ``remove''.
o Fix the bind()/connect()/accept() calls made by the MP server.
o Create bundle_SendDatalink() and bundle_ReceiveDatalink().
This allows `struct datalink's to flatten themselves, pass
through a pipe (read: the eye of a needle !) and come alive
at the other end. The donator then fork()s & exec()s pppmpipe,
``passing'' the connection to another ppp instance.

*** PPP NOW TALKS MULTILINK :-))) ***

Our link utilization is hideous, and lots of code needs
tidying still. It's also probably riddled with bugs !
It's been tested against itself only, and has hung once,
so confidence isn't high....

o Remove bundle_LinkLost() and have the modem routines simply
call datalink_Down() where appropriate rather than
modem_Hangup().
o Now, when something horrible happens (failed read/write, loss
of carrier etc), we go offline and run any hangup scripts etc
in a controlled manner - exactly the same as if someone says
``down'' at the prompt or sends us a HUP.
o -dedicated links that fail to make the modem raw close it,
suffer the redial timeout then try to open it again.

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.

o Move struct lcp and struct ccp into struct link.
o Remove bundle2lcp(), bundle2ccp() and bundle2link().
They're too resource-hungry and we have `owner pointers'
to do their job.
o Make our FSM understand LCPs that are always ST_OPENED
(with a minimum code that != 1).
o Send FSM code rejects for invalid codes.
o Make our bundle fsm_parent deal with multiple links.
o Make timer diagnostics pretty and allow access via ~t
in `term' mode (not just when logging debug) and
`show timers'. Only show timers every second in debug
mode, otherwise we get too many diagnostics to be useful
(we probably still do). Also, don't restrict ~m in term
mode to depend on debug logging.
o Rationalise our bundles' phases.
o Create struct mp (multilink protocol). This is both an
NCP and a type of struct link. It feeds off other NCPs
for output, passing fragmented packets into the queues
of available datalinks. It also gets PROTO_MP input,
reassembles the fragments into ppp frames, and passes
them back to the HDLC layer that the fragments were passed
from.
** It's not yet possible to enter multilink mode :-( **
o Add `set weight' (requires context) for deciding on a links
weighting in multilink mode. Weighting is simplistic (and
probably badly implemented) for now.
o Remove the function pointers in struct link. They ended up
only applying to physical links.
o Configure our tun device with an MTU equal to the MRU from
struct mp's LCP and a speed equal to the sum of our link
speeds.
o `show {lcp,ccp,proto}' and `set deflate' now have optional
context and use ChooseLink() to decide on which `struct link'
to use. This allows behaviour as before when in non-multilink
mode, and allows access to the MP logical link in multilink
mode.
o Ignore reconnect and redial values when in -direct mode and
when cleaning up. Always redial when in -ddial or -dedicated
mode (unless cleaning up).
o Tell our links to `staydown' when we close them due to a signal.
o Remove remaining `#ifdef SIGALRM's (ppp doesn't function without
alarms).
o Don't bother strdup()ing our physical link name.
o Various other cosmetic changes.

Also, deal with someone changing the clock while we're
sleeping (and restart the whole sleep).

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

I think this fixes the "magic is same" problems that some
people have been experiencing.
The man page is being rewritten. It'll follow soon.
