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.

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.

Eliminate all of the #ifdefs for the "strtc" driver. Define model
properties (similar to what the "dsrtc" driver does), and provide
DT compat strings corresponding to those models. Allow config flags
to specify the model for non-FDT platforms (also like "dsrtc").

Enable BUFQ_PRIOCSCAN, CARP, Veriexec by default in GENERIC kernel configs.
On ports without a GENERIC kernel config enable in individul files, e.g evbmips.
Omit on:
atari, dreamcast, emips, epoc32, evbppc/VIRTEX*, ia64, luna68x, mvme68k,
mvmeppc, playstation2, riscv, sun2, sun3, x68k, zaurus due to resource
constraints or port infancy.

Enable the per-priority cyclical scan buffer queue strategy on evbmips kernels.

Update description, nfc

Remove invalid option copy-paste from hpcmips.

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).

branches: 1.31.2;
Revert changes that pinned-down i2c parent specs. The i2c subsystem
has been enhanced to make this unnecessary.

Fully specifiy the location of indirectly-configured I2C devices. In
particular, the parent spec must not be wild-carded, as doing so doesn't
work well on systems where more than one I2C bus is present.

branches: 1.29.2;
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.

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

Add commented out bpfjit options to mips kernels.

Update all kernel configs mentioning WSEMUL_* but not already including
WSDISPLAY_COMPAT_USL using the following rules:
- If WSEMUL_ is commented out, add commented out out WSDISPLAY_COMPAT_USL
- If INSTALL or obviously memory constrained, add WSDISPLAY_DEFAULTSCREENS=1
and commented out WSDISPLAY_COMPAT_USL
- Otherwise add WSDISPLAY_COMPAT_USL

Some of the INSTALL configs for larger memory machines are probably suitable
for adding WSDISPLAY_COMPAT_USL.

Now wsconscfg(8) should be able to switch VTs when expected.

Implemented after no objection from tech-kern to the following:

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

branches: 1.14.2;

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.

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.

Remove unused count from pseudo-device md.

enable IPFILTER_COMPAT in all kernels that have ipfilter already.
canonicalise several of the ipf option segments in various files
(this mostly means adding commented out IPFILTER_DEFAULT_BLOCK,
or adding commented or uncommented IPFILTER_LOG or IPFILTER_LOOKUP
option statements.)

i built about 20 of these kernels to check, but not all of them.

Remove unused count (invariably "4") from pseudo-device fss.
