BREAK/parity/framing errors.
Term "correctly" assumes POSIX spec. and 4.4 ttyinput() behaviour.
1) Discard BREAK/parity at interrupt level when apropriate IGN*
is set in iflag. It helps "raw" mode works even IGN* is set.
2) Zero parity (if INPCK) and framing directly in buffer
before passing it to b_to_q() in "raw" mode.
Efficency:
interrupt level: if no error occurse, only two "test" commands added
"raw" mode: buf scan incc times for parity/framing added

include <pci/pcivar.h> without including <sys/devconf.h> and other
drivers include <pci/pcivar.h> before including <sys/devconf.h> if
certain identifiers are defined.
The devconf headers have convoluted interdependencies. <sys/devconf.h>
includes <machine/devconf.h> which includes <pci/pcivar.h>. Most
drivers include <sys/devconf.h> so even isa drivers depend on
<pci/pcivar.h>. For similar reasons, most drivers depend on another
pci header, on an isa header and on two scsi headers.
- ignore the partition table if it is identical with the bogus one in
/usr/src/sys/i386/boot/biosboot/start.S. Honoring the bogus size
field was fatal. The error is detected but other compatibilty
cruft weakens the error handling too much for this case.
- weaken the partition entry checking to allow the following treatments
of C/H/S addresses when C should be >= 1024:
(1) allow C = 1023, H = max, S = max.
(2) allow C to be correct modulo 1024.
Other compatibilty cruft weakens the error handling to allow all
C/H/S addresses, but there too many errors were reported.
Improve error messages:
- print C/H/S addresses if relevant.
- distinguish primary partition table from extended partition tables.
- don't use diskerr() except for i/o errors.

anyway.
Removed cnt.v_kernel_pages: We don't implement this and doing so accurately
would be very difficult (and ambiguous - since process pages are often
double mapped in the kernel and the process address spaces).

not going to argue! [Note to NetBSD folks: You're free to grab it now :-)]

in.c: when an interface address is deleted, keep its multicast membership

. next address on the same interface. Also, in_multi structures now
. gain a reference to the ifaddr so that they won't point off into

. done for routes, and seems to make the most sense.
function calls. Broken tracking of open partitions gets fixed as a side
effect. Races in sdopen() and sdioctl() become more numerous than before.
Close the device in sdsize(). Media removal could not have worked right
when unused swap devices were held open. There may now be a problem
with used swap devices not being held open.
Fix ancient operator precedence bug in sddump(). It may have been
possible to attempt dumping to unloaded media.
Remove NetBSD ifdefs. We're too different now, and the NetBSD driver was
already too different for them to be relevant.
Remove support for soft write protection. There are no ioctls to set it,
and this driver never set it either. It was used in the wd driver to
disable writing to unlabelled disk, but we want to support writing to
foreign partitions on unlabeled disks.
Clean up some formatting and restore some old-style function headers.

ultra14f.c and eliminate constants.
Correct EISA slot scan loops to look at slots 1 to 15 inclusive (off
by 1 errors all over the place). Other drivers need this, I will get
to it after a little more work.
Correct the ultrastore EISA probe so that it starts after the last
EISA slot probed instead of starting over from slot 0.
We need an eisa.h to move a lot of common constants into. I will
write it if someone tells me where it should go (sys/eisa?).
