Randall Hopper <rhh@ct.picker.com> GHUE/GBRIGHT bug
Louis Mamakos made a new bt848 struct, including massive changes to the entire
body of code, substituting array offsets with struct members.
Randall Hopper aadded fixes of BT848_GHUE & BT848_GBRIG.
I (fsmp):
added polled hardware i2c routines,
removed all existing software i2c routines.
added eeprom support.
print "at <not configured>" for iobase == -1 (autodetect not happens)
and not print anything for iobase == -2 (none)
Old code treat this two special config numbers as big port numbers.

<sys/ioctl.h> is included in the kernel. It still compiles.
This set of changes reduces the number of dependencies in LINT/.depend
from about 31000 to about 30000. This should make LINT kernels
compile a whole 1% faster. Further reductions to less than 20000
dependencies can easily be made. E.g., 20 headers of nested spam
from <sys/param.h> for 500 object files gives 10000 dependencies;
less than half of these are real.
<sys/filio.h>, <sys/sockio.h> and <sys/ttycom.h> instead of
<sys/ioctl.h> in a couple of files. This is still only 1/3
as spammish as <sys/ioctl.h> - 5 or 6 old tty ioctl headers
aren't needed.
<sys/ioctl_compat.h> and sometimes <sys/filio.h> instead of
<sys/ioctl.h> in tty-related files. <sys/ttycom.h> is still
usually imported bogusly via <sys/termios.h>.
<sys/ttycom.h> and sometimes <sys/filio.h> instead of <sys/ioctl.h>
in miscellaneous files. Most of these files have nothing to do
with ttys but need to include <sys/ttycom.h> to get the definitions
of TIOC[SG]PGRP which are (ab)used to convert F[SG]ETOWN fcntls into
ioctls.
doesn't happen to be included before this header.
This header was missed in previous cleanups because it didn't include
<sys/ioctl.h> or <sys/ioccom.h>. Clean it now:
- #include <sys/types.h> since it is necessary to make the header self-
sufficient (there are a couple of u_char's).
- uniformized idempotency ifdef. Copied the style in the 4.4Lite
ioctl headers.
caller is scsi_done which the controller interrupt handlers call. In the
case of a non-buffer based transaction, the xs structure is freed by the
process that initiated the transfer in scsi_scsi_cmd. In this case, an
explicit splbio/splx pair around the call to free_xs is required. Without
the splbio protection, the xs free list could be corrupted, and the type
driver's start routine might run without spl protection.

null casts. `time' is nonvolatile for accesses within a region locked
by splclock()/splx(). Accesses outside such a region are invalid, and
splx() must have the side effect of potentially changing all global
variables (since there are hundreds of sort of volatile variables like
`time'), so declaring `time' as volatile didn't have any real benefits.
form `tv = time'. Use a new function gettime(). The current version
just forces atomicicity without fixing precision or efficiency bugs.
Simplified some related valid accesses by using the central function.
