Rename auxreg.h because we need config to generate one now.

reference for making transferral of meta-information possible from
readdisklabel to bounds_check_with_label. The first (and maybe only)
thing that will use this is the multi-disklabel-format code on the
alpha where the labelsector is passed via cpu_disklabel so the label
write-protection can work correctly no matter what label was found.
Also use a new macro DKBAD to get at the dkbad field of the cpu_disklabel
implementations that contain it. This too is for multi-disklabel
architectures where the "bad" field can be inside a union. Use this
macro as a means for a driver to check if an architecture supports
dkbad constructs.
Remove proto of bounds_check_with_label from all MD disklabel.h as it
is in sys/disklabel.h.
I have not been able to test the changes everywhere, if I break anything
I apologize, and promise to fix it as soon as I become aware of it.

and uses our fdformat interface (same code base as NetBSD, with differently
named ioctls, but we have always preserved the names of the original code's
authors, unlike NetBSD...)

Kernel compile errors when AUDIO_C_HANDLER is defined, due to a
syntax error: *(foo->bar)++ is an odd bit of coding.

[1] check return value from malloc() for NULL before trying to bzero it.
[2] use "=" rather than "|=" when writing to CSR (otherwise you may
ACK something you don't mean to!).

[prevents disk_unbusy panic when disk is loaded (if no
free IOPBs, xdstrategy() would queue the buffer for pickup
by xdcintr() but xdcintr() would never call disk_busy().
xdc_startbuf() is a better place since all bufs are routed
through here] problem detected by girish@dworkin.wustl.edu,
diagnosed and corrected by me.
- move disk_unbusy() call in xdc_remove_iorq() before the call to
XDC_FREE() [don't want to access a data structure that was just put
on a free list]

zero since xdcmatch/xycmatch no longer sets it). [if you call
mapiodev() with a zero size it will reuse the KVA it returns, swiping
the device out from under you!]
- make xdc/xyc->iopbase point in the kernels DVMA space rather than at the
normal malloc'd KVA. this isn't compatable with sun4m [doesn't
have a kernel DVMA space] and will need to be changed later (XXX).
- move disk_attach() to before reading the disk label as per Jason.
otherwise we are reading into an unallocated buffer (oops!)

device address (bus_tmp, bus_map, and mapiodev now do this for us).
also, we handle all our mappings, so don't have obio.c do any for us
(i.e. don't set ra->ra_len in xycmatch).

and thus probed the wrong address on the 4/300 (but it worked because
it was probing the esp0 registers!).
now that bus_tmp() adds the offset in for us [as of obio 1.15] i
discoved that a byte access to the dma registers is not allowed.
so, i've change probeget to use a word access.

page boundaries:
- change bus_tmp() to include the offset from the start of page in the
returned KVA [rather than forcing each driver to add it back in
individually]
- changed bus_map() to include the offset from the start of page in the
the returned value if a mapping is found in the PROM's KVA area
- clarified a few comments

New generic disk framework. Highlights:
New metrics handling. Metrics are now kept in the new `struct disk'.
Busy time is now stored as a timeval, and transfer count in bytes.
Storage for disklabels is now dynamically allocated, so that the size
of the disk structure is not machine-dependent.
Several new functions for attaching and detaching disks, and handling
metrics calculation.
Old-style instrumentation is still supported in drivers that did it
before. However, old-style instrumentation is being deprecated, and
will go away once the userland utilities are updated for the new
framework.
For usage and architectural details, see the forthcoming disk(9)
manual page.
