* bus_setup_intr() as a wrapper for BUS_SETUP_INTR
* bus_teardown_intr() as a wrapper for BUS_TEARDOWN_INTR
* device_get_nameunit() which returns e.g. "foo0" for name "foo" and unit 0.
* device_set_desc_copy() malloc a copy of the description string.
* device_quiet(), device_is_quiet(), device_verbose() suppress probe message.
Add one method to the BUS interface, BUS_CHILD_DETACHED() which is called
after the child has been detached to allow the bus to clean up any memory
which it allocated on behalf of the child.
I also fixed a bug which corrupted the list of drivers in a devclass if
a driver was added to more than one devclass.
ACCMAP being REQuested by the peer, also increment our FSM
id so that we don't end up sending out a new REQ with the
same ID and different data (the changed ACCMAP).
log_in_vain:
log_in_vain turns on logging for packets to ports for which
there is no listener.
rc.sysctl:
A generic way to set sysctl values. It reads /etc/syslog.conf
and sets values based on that. No /etc/syslog.conf has been
checked in yet, and I've not added this to the makefile yet
until I get more feedback.

Well, better late than newer, but things has been hectic
around here, sorry for the long delay.
DMA support has been added to the ATA disk driver.
This only works on Intel PIIX3/4, Acer Aladdin and Promise controllers.
The promise support works without the BIOS on the board,
and timing modes are set to support up to UDMA speed. This
solves the problems with having more than one promise controller
in the same system.
There is support for "generic" DMA, that might work on other
controllers, but now you have been warned :)
More chipset specific code will come soon, I have to find testers
with the approbiate HW, more on that when I have it ready.
The system now uses its own major numbers, please run MAKEDEV
with the devices you need (ad?, acd?, afd?, ast?).
For now the disk driver will also attach to the old wd major
so one can at least boot without this step, but be warned, this
will eventually go away. The bootblocks will have to be changed
before one can boot directly from an "ad" device though.
Fixed problems:
All known hang problems should be solved
The probe code has been sligthly changed, this should solve
the reports I have lying around (I hope).
Hangs when accessing ata & atapi device on the same channel simultaniously.
A real braino in ata_start caused this, fixed.
As usual USE AT YOUR OWN RISK!!, this is still pre alpha level code.
Especially the DMA support can hose your disk real bad if anything
goes wrong, agaiin you have been warned :)
But please tell me how it works for you!
Enjoy!

changes have made this too expensive. This gains about 1.25% on
worldstone on my SMP machine.
Swap-less machines, for instance PicoBSDs, and machines which experience
page-out trafic, check with top(1), will probably want to reenable this
with:
ln -s H /etc/malloc.conf

longjmp. I suspect that the occasional double panic may be the result
of incorrect parameters to longjmp. This happens, of course, like the
entire file, only with -DVINUMDEBUG.
give_sd_to_plex: Don't set Raid-5 subdisk state here.
config_subdisk: handle the name parameter correctly when the subdisk
was referenced in a previous plex definition. The
name parameter must come first.
Handle autosizing relatively correctly. There is
still a danger of losing drive space if problems
occur with an autosized subdisk.
Set state to empty, not up, when complete. This also
solves a nagging problem about enforcing the need to
initialize RAID-5 plexes.
config_plex: handle the name parameter correctly when the plex
was referenced in a previous volume definition. The
name parameter must come first.
Handle initial state better.
update_plex_config:
Calculate the trim factor for RAID-5 plexes correctly.
Set the number of down subdisks correctly when reading
from disk config.
Remove comments about not being able to unload from the command line.
Add another example configuration output.
Clarify when to use 'vinum start' and when to use 'vinum read'.
subdisks in need of revival.
vinum_stop: sleep for a second before unloading. This solves a race
condition with a potential daemon when the stop command
is specified on the command line.

This code includes lots of stuff for verbose probing. I'm not 100%
sure that the output of the verbose probe is correct, but everything
else works fine, and -CURRENT was broken for the 5591 before, so I'm
committing it anyway.
