d_stop moved to struct tty.

These fields will be removed from struct cdevsw together with

The changes in this patch consist of:

initialize tty->t_stop
remove devtotty functions
rename ttpoll to ttypoll

method produce the entire device announcement message or
it prints "foo0: not found\n"
Alter sys/kern/subr_bus.c:bus_generic_print_child() to take on
the previous behavior of device_print_child() (printing the
"foo0: <FooDevice 1.1>" bit of the announce message.)
Provide bus_print_child_header() and bus_print_child_footer()
to actually print the output for bus_generic_print_child().
These functions should be used whenever possible (unless you can
just use bus_generic_print_child())
The BUS_PRINT_CHILD method now returns int instead of void.
Modify everything else that defines or uses a BUS_PRINT_CHILD
method to comply with the above changes.
- Devices are 'on' a bus, not 'at' it.
- If a custom BUS_PRINT_CHILD method does the same thing
as bus_generic_print_child(), use bus_generic_print_child()
- Use device_get_nameunit() instead of both
device_get_name() and device_get_unit()
- All BUS_PRINT_CHILD methods return the number of

The attached diff attempts to eliminate as much of the difference
between the i386 and the pc98 version of the file as possible. It
should not make any semantic difference (it consists of whitespace
changes, order changes, comment changes, changes of case for hex
constants, and merging in a couple of constants that hadn't made it

New function getmemsize_pc98 is added in this commit, since PC98 is
quite different in obtaining memory size from IBM-PC. Many lines of
this function is shareable with IBM-PC's getmemsize function, but
sharing needs many #ifdef PC98 statements. Therefore, I gave up
sharing code with IBM-PC's and just added new function.

perform a cleanup/unifdef sweep over it to tidy things up. The atapi
code is permanently attached to the wd driver and is always probed.
I will add an extra option bit in the flags to disable an atapi probe on
either the master or slave if needed, if people want this.
Remember, this driver is destined to die some time. It's possible that
it will loose all atapi support down the track and only be used for
dumb non-ATA disks and all ata/atapi devices will be handled by the new
ata system.
ATAPI, ATAPI_STATIC and CMD640 are no longer options, all are implicit.

Modify targets for debug kernels: when -g was specified, make will
now build a debug kernel called kernel.debug, and create a stripped
version called kernel at the same time. The two targets install and
install.debug are otherwise unchanged.
Requested-by: dillon
Update man page accordingly.
2. Config complains if you use -g:
Debugging is enabled by default, there is no ned to specify the -g option
3. Config warns you if you don't use -s:
Building kernel with full debugging symbols. Do
"config -s BSD" for historic partial symbolic support.
To install the debugging kernel, do make install.debug
(BSD was the name of the config file I used; I print out the same
name).
4. Modify Makefile.i386, Makefile.alpha, Makefile.pc98 and config to

5. Modify Makefile.i386, Makefile.alpha, Makefile.pc98 "clean" target

peripheral drivers can determine where in the devstat(9) list they are
inserted.
This requires recompilation of libdevstat, systat, vmstat, rpc.rstatd, and
any ports that depend on the devstat code, since the size of the devstat
structure has changed. The devstat version number has been incremented as
well to reflect the change.
This sorts devices in the devstat list in "more interesting" to "less
interesting" order. So, for instance, da devices are now more important
than floppy drives, and so will appear before floppy drives in the default
output from systat, iostat, vmstat, etc.
The order of devices is, for now, kept in a central table in devicestat.h.
If individual drivers were able to make a meaningful decision on what
priority they should be at attach time, we could consider splitting the
priority information out into the various drivers. For now, though, they
have no way of knowing that, so it's easier to put them in an easy to find
table.
Also, move the checkversion() call in vmstat(8) to a more logical place.
Thanks to Bruce and David O'Brien for suggestions, for reviewing this, and
for putting up with the long time it has taken me to commit it. Bruce did
object somewhat to the central priority table (he would rather the
priorities be distributed in each driver), so his objection is duly noted
here.
