Get rid of ac->ac_ipaddr and arpwhohas() since they assume that
an interface has only one address.

- Header prediction for ACKs did not exclude Fast Retransmit/Recovery.
- srtt calculation tended to get ``stuck'' and could never decrease
when below 8. It still can't, but the scaling factors are adjusted
so that this artifact does not cause as bad an effect on the RTO
value as it used to.
The paper also points out the incr/8 error that has been long since fixed,
and the problems with ACKing frequency resulting from the use of options
which I suspect to be fixed already as well (as part of the T/TCP work).

Add support for LKM operation.
Change M_NOWAIT on buffer memory allocation to M_WAIT in hopes we'll be
able to get ourselves a nice fat buffer from the kernel if we suspend.
Note: The LKM support looks kinda screwy in two areas, where I found
problems with the kernel proper. First, calling dev_attach()
at module load time will cause a panic. I haven't investigated.
Secondly, I had to manually call qcam_drvinit() to register the
device softc structure by hand at module load time. This seems
bogus, it should be called as a core part of the module load
process for character/block device drivers.
the precision; ANSI X3J11 is not crystal clear but certainly says
that the precision specifies the number of /digits/, and signs
and "0x" aren't really digits.
NetBSD already has a similar patch.
There needs to be a better way of doing this..
preferably we could add another pass to the
normal libc makefiles to do _r versions as well as _p versions
of a successful map retrieval. (This has to do with a previous change
to xdr_ypresp_all_seq() and ypxfr_get_map(); originally, yp_all()
would look for a return value of YP_FALSE to signal success, but now
it should be looking for YP_NOMORE. It should not be passing YP_NOMORE
back up to the caller though.)
Noticed by: <aagero@aage.priv.no>
There is also another small bug here, which is that the call to
xdr_free() that happens immediately after the clnt_call() in yp_all()
clobbers the return status value. I've worked around this for now,
but I think the xdr_free() is actually bogus and should be removed.
I want to check some more before I do that though.
Fixed the gets() changes. The buffer contents is indeterminate when
fgets() returns NULL... Now when you type EOT at one of the prompts,
the program usually spins reading the sticky EOF instead of dumping
core. Even GUIs could do better.
Added $Id$.

vm_offset_t is currently unsigned long but should probably be plain
unsigned for i386's to match the choice of minimal types to represent
for fixed-width types in Lite2. Anyway, it shouldn't be assumed
to be unsigned long.
I only fixed the type mismatches that were detected when I changed
vm_offset_t to unsigned. Only pointer type mismatches were detected.
