Add and enable dhcpcd for news68k installation.

news68k has already required two floppies since 9.0

Bump space for ramdisk image

Unreference IPF/PF from all the config files, and enable NPF instead when

IPF options while IPF was not compiled, IPF+PF enabled by default, etc).

clean up COMPAT_* options for native netbsd code:
- new series of files that are useful for saying "i want everything

many redundant options.

Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options
in ways that don't make sense; this should probably get cleaned up
too, but for the time being I've not added or removed anything.

Add commented out "#options COMPAT_70" to all kernel configuration

WABPL is no longer considered experimental (has not been for some time)
so update its comment in config files.

branches: 1.55.2;

The rnd pseudo-device is not really optional, because it is in the same
source file as the entropy-pool code itself. Move it to std. This
will be cleaned up more when I split the sources up as they should be.

This fixes build breaks on several ports. Thanks to Havard Eidnes for
pointing them out.

Add preliminary PROM internal function based framebuffer console support,

- map 0xc0000000-0xffffffff PA region (which is mirror of PA 0x0-0x3fffffff)
to the same VA via %tt0 and %tt1 registers and move KVA space accordingly

- save trap #0 vector for PROM function calls in early bootstrap

XXX: to attach wskbd(4) to non wsdisplay(4) devices like this romcons.

Bump the install image size from 1.5 to 1.6M so that it fits again.

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

Changes to MEMORY_RBFLAGS option:

- document this option inside options(4)

Bump install ramdisk image size from 1440k to 1500k, so that it fits again.
The install kernel is subsequently compressed, so there should be nothing

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.

enable USERCONF by default; it's small and extremely useful to have available.

Ensure all INSTALL config files consistantly include PIPE_SOCKETPAIR,
MALLOC_NOINLINE, and VNODE_OP_NOINLINE. The exceptions are when they
include another config files that already defines the options, or if
they are for an embedded board, just define a few extra options, and
do not already define PIPE_SOCKETPAIR.

Add the INCLUDE_CONFIG_FILE option to all config files. In config

Rename MEMORY_DISK_SIZE (formerly MINIROOTSIZE) to MEMORY_DISK_ROOT_SIZE,
which was suggested by Izumi Tsutsui <tsutsui@ceres.dti.ne.jp> as

* rename MINIROOTSIZE to MEMORY_DISK_SIZE, so that all md(4) options
