Make this compile again with options RESIDUAL_DATA_DUMP (Andrius V)

Rebase to HEAD as of a few days ago.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Count the number of CPUs at boot and stash in 'ncpu'. Eventually should
have each CPU register at attach, so we can figure out the topology for
the scheduler.

1) Modify pnpbus attachment code to properly decode pnp memory range packets.
2) Modify pnpbus attachment code to record the chipid of the device if it
   has one.
3) Change the clock probes to use the chipid, rather than relying on
potentially untrustworthy subtype and interface.
4) Add decoding of memory ranges to the RESIDUAL_DUMP code.
5) Add a we@pnpbus device to allow netbooting and root device detection
from an IBM we ethernet.  (it will only work if your firmware detects it)
6) Because I moved the pnpbus probe to occur prior to pci and isa, it
screwed up the root device detection and firmware path building code.
Completely rewrite the fw-path detection code to deal with this.

Rewrite the pci bus attribute decodings to be human-readable by using the
proper pcipnp structure file to read them rather than magical array offsets.

Add more complete decoding of the VPD, including extendedvpd, and TLB.  While
I was here, fix a bug where we never printed the L1 cache data properly.

Add code to decode small vendor items that are documented.  Namely we can
now decode the chipid, and L2 processor affinity data.

Also fix a bug where we were reporting the service processor type as a
memory controller.

Implement partial support for the RS6K PCI Bridge found on 7025-F40
models.  This code was made possible by assistance from Cory Bajus.

Add code that asks the PCI bridge what it's config base address is, and
use that when wiring up an indirect bridge type.
Move prep's user segment register to 10, because the 7025's PCI config
address is at 11, where the user segment used to be.
Add a battable entry for 0xbf800000 for machines with RS6K bridges.

There is still probably work left to be done before a 7025-F40 is fully
supported.

Add a small convenience function

Make this build again with RESIDUAL_DATA_DUMP defined.

Prep super-commit:

1) create new pnpbus psuedo bus.  This is a bus layer that reads the PNP
tree from the residual data and allows attachment of devices with the
information given therein.  Based loosely on i386/pnpbios.

2) Delete obio bus, as with the pnp bus we no longer need it.

3) Create a number of functions that gather the information needed to set
up the machine from the residual data, rather than hardcoding it in.

4) Create a quirk table for machines that are bizzare enough that the
residual information is not sufficient.  (such as the 6015)

5) Using the data gathering routines and the quirk table, delete struct
platform completely from the architecture.  Prep is now almost completely
dynamic in figuring out the machine it is running on and setting things
up properly.

6) Add a wdc_pnpbus driver which attaches the wdc controller found on
some 7248's and the 6015.  This replaces the now-defunct wdc_obio.

7) delete all the mot_* and ibm_* files, and replace them with a single
ibm_machdep.c which only contains the quirk functions for the 6015 and
the 6050.

8) Modify GENERIC to work with all this stuff.

sync with head.

1) Change the offset for each of the chunks of printed dump data from
a tab to two spaces.  This allows more space for some of the large vendor
items we wish to print.
2) Add decoding of a number of large vendor items of particular interest
to anyone wishing to port NetBSD to a prep machine.
3) Add a small convenience function which will be used by other pnp functions
in the future.

Sprinkle const around to make this file actually compile again.

merge ktrace-lwp.

Sync with HEAD. Here we go again...

Yes, it was a cool trick >20 years ago to use "0123456789abcdef"[a] to
implement, xtoa(), but I think defining the samestring 50 times is a bit
too much. Defined HEXDIGITS and hexdigits in subr_prf.c and use it...
