d1a795a280 Fix cblock starvation bugs by reserving enough cblocks for minimal 
operation of each clist.  Limit the growth of each clist.  Clists
can only grow larger than the reserved minimum if there are free
cblocks in a shared pool.  The size of this pool is now fixed
(this could be improved).  The reserved and maximum sizes are more
carefully allocated for slip and ppp, depending on the mtu.  A maximum
MTU of 16384 is now enforced for ppp.

a6a21d9edf Don't attempt to free null cblocks. There may be less to free than 
normal due to cblock resource starvation or malloc() failing when
the device is opened.

bb56ec4a05 While in the real world, I had a bad case of being swapped out for a lot of 
cycles.  While waiting there I added a lot of the extra ()'s I have, (I have
never used LISP to any extent).  So I compiled the kernel with -Wall and
shut up a lot of "suggest you add ()'s", removed a bunch of unused var's
and added a couple of declarations here and there.  Having a lap-top is
highly recommended.  My kernel still runs, yell at me if you kernel breaks.

329cfeccd5 Don't panic if we can't malloc a cblock...just print a console message 
and be happy.

b6504a8d7c Completed version of my clist management code. Requires hooks in tty.c 
for adding and removing cblocks from the cfreelist queue (to give them
back to malloc). I'll add those tomorrow.
