Resolve a couple of conflicts (result of the uimin/uimax changes)

Fix some min/max -> uimin/uimax stragglers.

We have three sets of DTYPE_ constants in the kernel:
	altq		Drop 		Type
	disklabel	Disk 		Type
	file		Descriptor	Type
(not to mention constants that contain the string DTYPE).
Let's make them two, by changing the disklabel one to be DisK TYPE since the
other disklabel constants seem to do that. Not many userland programs use
these constants (and the ones that they do are mostly in ifdefs). They will
be fixed shortly.

Rebase to HEAD as of a few days ago.

ANSIfy functions with function-pointer arguments

ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

Replace the myriad copies of bounds_check_with_label() with a single MI
version.

Add disk_blocksize(9) so that disk drivers can record the physical
block size of a disk if it is different to DEV_BSIZE. Right now this
simply initialises dk_blkshift and dk_byteshift according to the
supplied block size. This information is used in the MI version of
bounds_check_with_label().

Adapt to -Wcast-qual by adding a few consts.

Commit changes proposed on tech-kern Thu, 6 Nov 2003
- factor out disksubr.c between sun3, sparc and sparc64. Keep the sun3
  groveling code to find a NetBSD disklabel in the first sector (so that it
  can find a label at the old sun3 LABELOFFSET) as a fallback is not
  label at LABELOFFSET, or sun label is present.
- Fix the sun3 LABELOFFSET (was 64, but the kernel wrote the NetBSD label at
  128)
- Make next68k disksubr.c always write a next-compatible disklabel.
- remove #ifdef __sparc__ hack from disklabel(8), and change it to issue
  a DIOCWDINFO after writing the disklabel to the raw partition in the
  -r/-I case (so that the kernel can convert the label if needed).

move structs nextstep_disklabel/cpu_partition and appendant #defines
to sys/sys/bootblock.h
- rename to next68k_disklabel and next68k_partition
- use {u,}int{8,16,32}_t instead of char/short/int (suggested by D. Laight)

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

__KERNEL_RCSID()

Change bounds_check_with_label() to take a pointer to the disk structure,
rather than the label itself.  This paves the way for some future changes.

Change return type of readdisklabel() to const char *
I hope I've found all the correct places!

Track the SBSIZE -> SBLOCKSIZE rename done by the UFS2 merge.

Apply patches from Christian Limpach:

    - NeXT label reading support
    - SCSI dma fixes
    - media support for if_xe.c

Some of these need more cleanup, but at least make SCSI support usable on
the NeXT.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

rationalize the use of b_flags for geteblk() buffers.
rather than assigning to the whole field, set or clear individual flags,
which implies that the B_BUSY and B_INVAL flags will remain set.
this allows us to make the assertion in brelse() that B_BUSY is set,
which is the purpose of all this.

Nuke dk_establish() from orbit except from those ports which still use
it to determine the boot device: mvme68k, pc532, macppc, ofppc.  Those
platforms should be changed to use device_register().  In the mean time,
those ports defined __BROKEN_DK_ESTABLISH.

Initial commit of recent changes to make DEV_BSIZE go away.

Runs on i386, needs work on other arch's. Main kernel routines should be
fine, but a number of the stand programs need help.

cd, fd, ccd, wd, and sd have been updated. sd has been tested with non-512
byte block devices. vnd, raidframe, and lfs need work.

Non 2**n block support is automatic for LKM's and conditional for kernels
on "options NON_PO2_BLOCKS".

Sync'ed more files and routines with mvme port in prepartion for UVM.
Now use generic m68k cachops everywhere rather than defining them in locore.s

Started the esp scsi driver.
Fixed bus_space_handle_t in nextdma device.
Fixed scsi interrupt define.

Initial import of NetBSD/next68k.
