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.

Move the idle timer into struct bundle. There's no
link-level idle timer for the moment.

Move phone numbers into struct datalink.
Make "show modem" look a bit prettier.

o Move all device names into struct physical.

o Use a default list of "cuaa1, cuaa0" rather than
just cuaa1 and allow embedded spaces as separators.

Do authentication at the datalink level, not the bundle level.
The bundle doesn't get a LayerUp 'till we're authenticated.

o Remove the global CcpInfo. It's now part of the datalink.
Struct bundle will have its own struct ccp in the future
too.
o The ``set stopped'' command now requires context and doesn't
work on the IPCP FSM.
o Check if it's time to break out of our top level loop before
doing a select - otherwise, we'll select forever :-(
o Remove `struct link'::ccp (a temporary hack). It turns out
that IpStartOutput() calls link_Output() and link_Output()
incorrectly calls StartOutput() (really modem_StartOutput)
requiring the ccp knowledge so that it can call
IpStartOutput()... The end result is that the whole IP
output queue gets dumped into the modem output queue
and a pile of physical writes are done prematurely. This
makes the (original) code in main() actually work in that
it would not bother selecting() on the tun descriptor when
our modem queue length was 20 or greater. Instead, we now
make that decision based on the overall queue length.

This will need improvement later.

Keep a handle on our current ``term'' in struct prompt

Introduce the ``link'' command for controlling

Sort out (fix) the `term' command.
datalink_Up() can now be told to skip the dial/login/hangup
scripts and can be told whether to enter packet mode when
entering the DATALINK_OPENED state.

Move the redial timeouts and max tries into struct datalink.

Move the reconnect timeout and max tries into struct datalink.

Move the dial, login and hangup scripts into struct datalink.
Don't set these scripts in -direct mode.
Always set reconnect_tries to zero for -direct mode.

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 !

The hooks in DoLoop() in main.c are *very* messy ! I'll have
