Add and enable WSDISPLAY_SCROLLSUPPORT in non-INSTALLish macppc kernels

Also, fix the whitespace of this line in the GENERIC_601 kernel where it
was already enabled.

Add and enable WSDISPLAY_CUSTOM_OUTPUT in macppc non-INSTALL kernels.

Indirectly addresses PR 59079 by allowing userland control of default
colors of wsemul wsdisplays.

Mention DKWEDGE_METHOD_TOS in several kernel config files

PR/57889: Ricardo Branco: ext2fs does not have user immutable and append
file flags, only system ones. Restrict those to the superuser. Before
the behavior was controlled by EXT2FS_SYSTEM_FLAGS. Make that behavior the
default.

UFS/LFS dirhash:
- Enable UFS_DIRHASH if the architecture or kernel model specific config
file can use 128MB of RAM or more.
- Remove experimental tag from UFS_DIRHASH; it's been with RUMP kernel
and by a number of NetBSD developers for years.
- Add LFS_DIRHASH if LFS was enabled.
- Be somewhat consistent with FS options order.

add a commented out compat_ossaudio wherever there's compat_linux

vether: Add to kernel configurations

It's only enabled if the kernel enabled bridge AND tap.
Otherwise it's commented out.

Remove references to BRIDGE_IPF, it is now compiled in by default.

remove 'file-system SMBFS' and 'pseudo-device nsmb' from all kernel configs
to prepare for their eventual removal

Synchronize htdocs, manual, comments, and code so that enabling the platinumfb is done using "platinum" in openfirmware settings. Remove "screen" option which was somewhat disingenuous.

Use veriexec.config to reduce duplication

increase MEMORY_DISK_ROOT_SIZE slightly to avoid running out of space
when doing some sysinst options.

Add ahc and rtk options for my testing convenience. The 601 kernels
are still small enough for netbooting.

Add scroll support, wsmouse

Unreference IPF/PF from all the config files, and enable NPF instead when
wanted. This also fixes some inconsistencies I saw in several files (eg
IPF options while IPF was not compiled, IPF+PF enabled by default, etc).

Remove support for macofcons(4), it's not actually possible to build a kernel
with it enabled - See PR port-macppc/53004 and it may have further problems even
so.
From <macallan>:
"There is some early console code that uses OF output but it causes problems
when we get close to MMU setup - I think it can go, it hasn't been enabled in
any config in at least a decade as far as I know."

Remove legacy comment regarding the instability of awacs(4)
Enable awacs(4), skipping MAMBO config as it is for an emulator.

From <macallan>
"that warning about the awacs driver making some
machines lock up can probably go. It's ancient and I've never seen it
actually happen, I have several oldish macs with different awacs
variants and it's enabled in all my configs. In fact it predates my
macppc interrupt cleanup ( I think I did that in 2005 or so ) and I
strongly suspect that fixed the problem.
( the ancient code didn't properly distinguish between edge and level
triggered interrupts on grand central / heathrow type hardware, IIRC it
always just checked the level register(s) which resulted in edge
triggered interrupts being missed or misdetected. Most of the mac-io
goop from that time uses edge triggered interrupts, which includes
awacs )

If this actually happens to anyone I'd like to know about it"

Enable BUFQ_PRIOCSCAN by default for NetBSD/macppc.
Drop references to NEW_BUFQ_STRATEGY and replace with currently available
options BUFQ_READPRIO and BUFQ_PRIOCSCAN.

ok <macallan>

With the introduction of ddb.dumpstack which is enabled by default, we no longer
need to explicitly set DDB_COMMANDONENTER to run a trace.

Alternate buffer queue strategies no longer considered experimental, update
description.

clean up COMPAT_* options for native netbsd code:
- new series of files that are useful for saying "i want everything
since netbsd 1.4", etc.
- use the fact COMPAT_* options have future dependancies to remove
many redundant options.

removes about 3000 lines total across kernel configuration files.
tested about 30 random kernels in the changed list.

Remove support for VERIFIED_EXEC_FP_RMD160, VERIFIED_EXEC_FP_SHA1, and VERIFIED_EXEC_FP_MD5 options.
These algorithms are either broken or on their way to being broken.

Remove TCP_COMPAT_42 from the config files. Pass 3.

Add DKWEDGE_METHOD_RDB option, which is enabled for x86, commented out for
other platforms by default.

wildcard speaker attachments, now that we can handle many of them.

remove VAUDIOSPEAKER for now, will be done differently.

Add a synthesized pc beeper and keyboard bell for platforms with an audio
device.

RADEONFB_MMAP_BARS is no more

Disable BSDLABEL and MBR DKWEDGE methods again since sysinst does not work
with wedges.

Create an "options MODULAR_DEFAULT_AUTOLOAD" config option and add
it to all kernel configs that contain "options MODULAR". This
option turns on module autoloading by default (which is the current
default). This allows people who don't want module autoloading on
by default to disable it by simply removing/commentting this line.

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.

branches: 1.3.2;
- Enable Wedge support for MBR/BSDLABEL where it was commented out.
- Add apple partition support where it was missing
- Add comments where missing

Add "options COMPAT_70" to all kernel configuration files that
already had "options COMPAT_60".

config goop for ppc601 support
GENERIC_601 more or less resembles a Power Macintosh 7200 with a few drivers
thrown in for convenience while keeping the kernel itself smaller than 4MB
