Added idempotency guards to <machine/conf.h>. "ioconf.h" can't be

Fix the tests for being a console by reverting to the ones that
were used before the the RB_SERIAL changes. RB_SERIAL only needs
to be tested in one place. The initialization of comconsole was
wrong before the RB_SERIAL changes for the COMCONSOLE case. This
may have been the cause of the unnecessary changes.
Start eliminating #includes of <i386/i386/cons.h>. This header is
supposed to be included from <machine> although it should be
completely machine-independent and included from <sys>.
Remove a wrong XXX comment. `comconsole' is used to test for being
a console and even the tests for deciding the default termios state
are necessary (the semi-reentrant i/o routines don't handle ordinary
device i/o).

that every PCI motherboard did ...
Change the test on the initial value of the CONF1_ADDR_PORT register in a way
that makes the probe succeed on triton based motherboards, without breaking
the EISA motherboard that has some non-PCI register at the same address.
Require the state of the configuration enable bits to be OFF assuming
that the BIOS left them that way, as it should anyway to avoid bad things
to happen.
The tests themselves are copied from the previous release, with the
exception of CONF1_ENABLE_MSK1 having the LSB set. This bit should be
read back as '0', since only DWORD addresses are legal.
I tried to solve the problem of IDE probing compatibility in this version.
When compiled without an ATAPI option, the wd driver is
fully backward compatible with 2.0.5. With ATAPI option,
the wdprobe becomes strictly weaker. That is, if wdprobe works
without ATAPI option, it will always work with it too.
Another problem was with the CD-ROM drive attached as a slave
in the IDE bus, where there is no master. All IDE CD-ROM
drives are shipped in slave configuration, and most users
just plug them in, never thinking about jumpers.
It works fine with ms-dos and ms-windows, and this
version of the driver supports it as well.
The eject op can now load disks. Just repeat it twice,
and the disk will be ejected and then loaded back.

This all works now.
o A change so that xcdplayer gets TOC entry data for the lead-out area
on the disc. Xcdplayer can now play the last track on a CD, which
it would not do in earlier versions (but no one reported).
Cdplayer gets the TOC data differently and it works in old and new
versions.
o Eliminated a race condition that caused the driver to sleep forever
on very slow and heavily loaded systems on rare occasions when
the system was doing lots of audio-related ioctls to the drive.
o Fixed a problem where a locked drive could be unlocked by accessing
one of the non-locking devs. Door locking now follows the documented
rules.
o Made all wait channel strings unique to matcd.

Original message:
This patch upgrades the ATAPI CD-ROM driver to version 1.3.
It has three bugs fixed:
1) The `controller not ready' message at startup and later.
It was caused by staled media change bit.
2) Incorrect shuffling of model string for some drives (NEC, Mitsumi).
3) Handling of drives which report itself as been of direct-access type,
instead of CD-ROM type.
There is one known bug which is not fixed yet -- probing
in absense of IDE disks. A work-around exists though (thanks Steve!).
If you have no IDE disks attached, then remove them from the kernel
config file to make the CD-ROM attach correctly.
Unfortunately, there is no way to disable them from the kernel
interactive config mode.

This change forces the controller drivers to allocate a scsibus_data struct
via a call to scsi_alloc_bus(), fill in the adapter_link field, and optionally
modify any other fields of the struct. Scsi_alloc_bus() initializes all fields
to the default, so the changes in most drivers are very minimal. For drivers
that support Wide controllers, the maxtarg field will have to be updated to
allow probing of all targets (for an example, look at the aic7xxx driver).
Scsi_attachdevs() now takes a scsibus_data* as its argument instead of an
sc_link*. This allows us to expand the role of the scsibus_data struct for
other bus level configuration setings (max number of transactions, current
transaction opennings, etc for better tagged queuing support).

Fix an interesting feature that caused 8-bit chars to loose their top bit

This finishes the remaining outstanding problems that I'm aware of, with
the exception of efficiency... Optimizing can come later after it's fully
debugged.

Note that it still (for reasons unknown) appears to be masking data to
