b4f63b0b8b When logging warning messages, there are now three scenarios:
o If a prompt is executing the command, only display the warning to
  that prompt
o If a prompt is executing a ``load'' command, display the warning
  to all prompts *and* syslog
o Otherwise, display the warning to all prompts *and* syslog.

3377c28cd9 Deal with the fact that as we now mbuf_Read the fsm
header in fsm_Input() we often end up with a NULL mbuf.

Deal with a possible NULL mbuf being passed into
mbuf_Prepend().

Adjust some spacing to make things more consistent.

5d9e610366 o Redesign the layering mechanism and make the aliasing code part of
the layering.

  We now ``stack'' layers as soon as we open the device (when we figure
  out what we're dealing with).  A static set of `dispatch' routines are
  also declared for dealing with incoming packets after they've been
  `pulled' up through the stacked layers.

  Physical devices are now assigned handlers based on the device type
  when they're opened.  For the moment there are three device types;
  ttys, execs and tcps.

o Increment version number to 2.2
o Make an entry in [uw]tmp for non-tty -direct invocations (after
  pap/chap authentication).
o Make throughput counters quad_t's
o Account for the absolute number of mbuf malloc()s and free()s in
  ``show mem''.
o ``show modem'' becomes ``show physical''.

c9e11a112d Fix a rather nasty use of `static'. This caused a SEGV
when running ``link * load label'' as we ended up recursing
back into command_Interpret after nuking our command arg list.

d91d286164 MFMP: Make ppp multilink capable.

dd0645c5b7 o Add the `set mode' command for change a links current mode. It
is not possible to switch to or from dedicated or direct mode,
  but all other combinations are ok (eg. -auto -> -ddial).
o Cope with the fact that commands with optional context may not
  be able to obtain a link with command_ChooseLink() (if all links
  have been deleted for example).
o Allow `clone'ing in non-multilink mode.  We may for example want
  to configure two links in unilink mode and dial them both, using
  the one that comes up first.  It's also possible to rename
  ``deflink'' by cloning it, deleting the original, then setting
  the mode of the new link.

6f38457323 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....

250920922b Pass all command arguments around with struct cmdargs rather
than incrementing argv and decrementing argc.  Now individual
functions can determine their caller.  This also removes the
"prefix" hack in FindExec().

565e35e50e 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.

b6217683dc 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.

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.

72ca96bfa5 o Log ******** instead of the actual password for "set authkey"
when command logging is switched on.
o Display ******** for the authkey for "show auth"
o Document how \P should be used, and document the other chat escapes
  while I'm there.
o Make sure the full command is displayed when a compound command
  fails - ie, "set novar rubbish" should say "set novar: Invalid command"
  rather than "novar: Invalid command"
