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.

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.

o Move alias function pointers into loadalias.c o Move Var*Version into command.c o Remove struct pppVars (and there was much rejoicing) ! o Forward-decl some structs in .h files to avoid include ordering requirements and remove a few more redundant #includes.

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''.

o Rename datalinks as soon as the name has been received so that LQM and HDLC timer diagnostics come out with the correct name. o Don't send an LQR immediately upon reviving a datalink. Leave it 'till the next timeout. o Add the link name to some more LQR diagnostics. o Break out of the main loop when a descriptor exception is seen in select(). o Remove the evil nointr_[u]sleep() functions. Timers should be (and are) used instead. o Treat a read() of 0 bytes as an error that's fatal to the link on which the read() is done. We should never read() 0 after select() says there's something there - not unless the link has been closed by the other side. o Write the data seen before a HDLC header to the terminal in `term' mode, *not* back to the modem :-/ o Initialise our transmitted file descriptor before starting any timers. o Only send data links that have *no* pending output data. This means that our final ACK will be written rather than being nuked with the datalink transmission.
