Add support for tagged queuing on ATA drives. There is only support for
IBM's DPTA and DTLA series of drives (no other disk vendors are known
to support this) on non-Promise controllers (promise controllers lockup
when given the tagged queuing specific commands).
It gives especially master/slave comboes about 5% better performance.

Add support for the Promise ATA100 OEM chip (pdc20265)

Add support for the Cyrix 5530

Change the way status is read from the drives, use the alternate
status reg when possible.

Better support for DEVFS, the acdXtY devices are now created when needed.

Lots of little cleanups.

* Completely rewrite the alpha busspace to hide the implementation from
the drivers.
* Remove legacy inx/outx support from chipset and replace with macros
which call busspace.
* Rework pci config accesses to route through the pcib device instead of
calling a MD function directly.

With these changes it is possible to cleanly support machines which have
more than one independantly numbered PCI busses. As a bonus, the new
busspace implementation should be measurably faster than the old one.

Fix the ICH2 ATA100 support, and proberly downgrade the chip setup when
going to slower DMA modes on all Intel chips.

Add experimental code for ATA100 support on:

Promise Ultra100 / Fasttrak100
HighPoint HPT370 controllers (fx Abit KA7-100 onboard ctrl, Abit HotRod 100)
Intel ICH2 (Intel 815E based motherboards)

So far I can read >90MB/s on the Promise and the HPT370.
I can write >64MB/s on the promise and >50MB/s on the HPT370 so it seems
writing is still done in ATA66 mode :(
The ICH2 support is untested as of yet...

Separate the struct bio related stuff out of <sys/buf.h> into

<sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall
not be made a nested include according to bdes teachings on the
subject of nested includes.

Diskdrivers and similar stuff below specfs::strategy() should no
longer need to include <sys/buf.> unless they need caching of data.

Still a few bogus uses of struct buf to track down.

arise in DMA mode.

Support the CMD646 chip which is used on many alphas, sadly only
in WDMA2 mode, as the silicon is broken beyond belief for UDMA modes.

Lots of cosmetic fixes here and there.

Sorry for the size of this megapatchfromhell but it was not
possible otherwise...

Repeat the identify command if drive fails the first.

Protect the timeout functions with splbio.

Dont update the transfer details before we are sure the transfer
succeded, this way they are proberly retried on errors.

Move the handling of next_writeable to userland.

Use the READ_CD command to read CD's. That enables us to read _anything_
via the normal read/write interface. This kindof obsoletes the READAUDIO
ioctl, but we keep that for now.
