PR 56829: Fix "map" call to Open Firmware and no longer mess up OFW stack.
This unbreaks miniroot.fs.

Thanks to Björn Johannesson for originally pointing this out and to
mrg@ for pointing out the actual issue and suggesting a fix.

Add more details about the boot device as a new bootinfo record type.
From within the bootloader, when we have readily accessible instance
handles of the boot device, it is easy to query more details like SCSI
LUN, target, and FC-AL wwn from the firmware.
The kernel later would have a hard time getting theses, but can make good
use to match the boot device.

Add compile time asserts to make sure we have properly picked up types
for a 64bit cpu and 64bit openfirmware.

Fix kernel loading failures from partitions started from over first
4GB of disks on sparc64.

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.

GCC_NO_FORMAT_OVERFLOW variables to remove these warnings.

apply to a bunch of the tree. mostly, these are real bugs that
should be fixed, but in many cases, only by removing the 'packed'
attribute from some structure that doesn't really need it. (i
looked at many different ones, and while perhaps 60-80% were
already properly aligned, it wasn't clear to me that the uses
were always coming from sane data vs network alignment, so it
doesn't seem safe to remove packed without careful research for
each affect struct.) clang already warned (and was not erroring)
for many of these cases, but gcc picked up dozens more.

More -Wno-error=address-of-packed-member to placate clang.

- Enable NFS_BOOT_DHCP (as well as the existing NFS_BOOT_BOOTPARAM).
DHCP/Bootp is tried before bootparams in the MI nfs mountroot code.
- Change the order in boot.net from "bootparams then bootp" to
"bootp then bootparams", to be consistent with the MI nfs mountroot code.

(Consistency with other NetBSD ports is good, and things still work
for sites that run bootparams but not dhcp/bootp, although I'd argue that
dhcp/bootp is much easier to setup and manage and is easier to debug
than our rpc.bootparamd...)

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.

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

Make filename() only return a partition if it actually found one in
the path.

Some aliases (like "cdrom") expand to a path that includes a partition -
deal with them.

Change "Boot:" prompt option parsing to be more in line with the default
(no prompt) behaviour - it is now possible to "boot net:dhcp -a" and then
say "disk" at the "Boot:" prompt - result should be equivalent to "boot disk",
but the ofwboot was loaded from the network.
While there fix a few minor errors, and one significant: if the "a" partition
should not start at the beginning of the disk, the previous code failed
to read a disklabel. Use the "c" partition now to find the disklabel now
always.

Rename the option to enable ISO 9660 file system support from ..._HSFS
to ..._CD9660.

Make sure the buffer used to read from disk is properly aligned to cast
it into a struct disklabel pointer w/o alignement problems.
