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: 1.56.2;
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.

Add `pseudo-device ksyms' where `options DDB' is used, because
config(1)/config(5) can't handle module dependency correctly at this
moment.

(This is another proof that shared file definition (`file xxx.c a|b')
is a bad idea.)

branches: 1.54.2;
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 bpfjit options to mips kernels.
While here, add 2 missing RCS ids.

branches: 1.52.4;
G/C PFIL_HOOKS from the kernel configs.

remove obsolete networking options

the bogus number police

remove confusing numeric locators where they are unused.

Under FAST_IPSEC, IPSEC_ESP is mandatory; GC it.

Retire OSI network stack. OK core@

branches: 1.46.6;
WABPL is no longer considered experimental (has not been for some time)
so update its comment in config files.

branches: 1.45.2;

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.

branches: 1.44.4;
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.

See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html
for details.

branches: 1.43.2; 1.43.4;
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.

branches: 1.40.2; 1.40.4;
Remove the portalfs kernel file system driver. Replace mount_portal(8)
with a version based on puffs. User functionality remains the same.

Remove softdep, pass 1. We are focused on improving journalling.

Proposed on tech-kern@.

PR/34283: Gene ENonymous: Add IPFILTER_LOOKUP to the default kernel options
Also remove CCITT,NS,NIP

Add stf to all kernel configs which have INET6 and gif, except the INSTALL
ones and those for specific machines of developers. PR 32304.

OK'ed by rpaulo.

N.B. stf is a cloning device, so it still must be enabled by
"ifconfig stf0 create".

branches: 1.32.2; 1.32.4; 1.32.6;
Remove 'count' argument for pseudo-devices that ignore it
(vnd, bpfilter, ppp, gif, gre, tun, sl, strip, faith, stf).

bpfilter doesn't accept count anymore.

branches: 1.30.2; 1.30.4; 1.30.6;
Remove obsolete options VNODE_OP_NOINLINE.

Adjust comments for options FFS_NO_SNAPSHOT.

XXX: This option should be mentioned in options(4).

Enable ptyfs by default on the non-install and non small/tiny/ramdisk kernels

revert "defflag VMSWAP" changes for now.
there seems to be far more people who don't want to edit
their kernel config files than i thought.

add "options VMSWAP" to non INSTALL kernels.

Add (commented out) IPSEC_NAT_T option.

branches: 1.24.4; 1.24.6;
Invert FFS_SNAPSHOT to FFS_NO_SNAPSHOT

Add 'option FFS_SNAPSHOT' to most of the config files.
Commented out for kernels that appear to hace space constraints.

Add file system snapshots to kernel configs.

- Ffs internal snapshots get compiled in unconditionally.

- File system snapshot device fss(4) added to all kernel configs that
have a disk. Device is commented out on all non-GENERIC kernels.

Add "options SYSCTL_INCLUDE_DESCR" to a lot of configs, but commented
out in most of them.

Move -mips2 to CPUFLAGS in each kernel config file as suggested by mrg.
This matches the way other ports specify default CPU codegen options.

Bye Bye UCONSOLE

comment 'makeoptions DEFGP="-G nn"' to resolve gp-size overflow.
even NULLCONF requires "-G 0".
fix PR kern/19184.

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

Enable "pseudo-device clockctl" in all kernels, except
installation related kernels (INSTALL* and RAMDISK*).
This enables rc.conf(5) $ntpd_chroot to be used "out of the box"

branches: 1.6.2; 1.6.4;
Add the INCLUDE_CONFIG_FILE option to all config files. In config
files that are generic (ie, GENERIC, GENERICSBC, GENERIC32, ALL, or
ALPHA), it is uncommented.

Add commented-out USERCONF option. Mainly useful for install media
and can be optionally enabled based on miniroot and ramdisk size
requirements.

branches: 1.4.2; 1.4.4;
Added vripif.

add options PIPE_SOCKETPAIR to individual kernel configs
the option is commented out on everything but kernels I was able
to recognize as INSTALL-like or ones for small memory machines

Adjusted GP size.
