vether: Add to kernel configurations

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

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 the KMEMSTATS option. It no longer exists.

branches: 1.41.2;
Add "no options COMPAT_70" to all kernel configuration files that
already had "no options COMPAT_60".

Add "no options COMPAT_60" to all kernel configuration files
that already had "no options COMPAT_50".

branches: 1.39.2; 1.39.12;
Add the MI software watchdog to GENERIC (not to SMALLRAM, as usual).

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.

One more page in the Big Book Of Things That We Can do Without --
COMPAT* options, puffs support.

branches: 1.36.4;
remove rest of 'no file-system PORTAL' (portalfs kernel driver was removed)

Remove various COMPAT_ options for unsupported releases and optional
features; remove parallel printer driver.
Bring back pppoe support.

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

Proposed on tech-kern@.

Remove LKMs and switch to the module framework, pass 1.

Proposed on tech-kern@.

No WAPBL (ffs journaling) for memory-strapped machines.

branches: 1.31.4; 1.31.6; 1.31.10;
Add explanation for the sbc flags to the kernel configurations that
use the sbc 53c80 driver. Until now, this information has lived in the
source code, only; neither sbc nor ncrscsi have a man page.

Triggered by PR port-mac68k/2921

branches: 1.30.16;
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.

Leverage the new config(8) options for disabling features. This way,
it is easier to keep kernel configuration files up-to-date.

While we are here, disable a few compat options - NetBSD 1.5 has been
a while.

Tested on a Macintosh SE/30 with ae(4) ethernet card.

Rather than attaching fpu as a usual device during cpu_configure(9),
initialize it explicitly in identifycpu() (before cpu_configure(9))
because after yamt-idlelwp merge savectx() is called before
cpu_configure(9) and it requires fputype initialized properly,
otherwise a kernel fails in savectx() if a machine doesn't have an FPU.

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

branches: 1.26.2;
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.

Remove the tablet line discipline.

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

64 bit inode changes.

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: 1.17.2; 1.17.4;
Add COMPAT_20 (and COMPAT_16 in some cases) to kernel config files
that didn't have those options but had other earlier compat options.

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.

only one of the obio locators was actually used, so get rid of the others
and collapse the two variations of obio into one. use the remaining locator
("addr") to differentiate the two possible esp and sbc devices (instead of
using the unit number).

Add tap(4) support to a random^Wcarefully chosen set of kernel configs.
All those kernels have a line for both tun and bridge, and if either is
commented out, tap is commented out also. With the exception of i386's
GENERIC_TINY.

XXX: we _need_ some way of making this more simple.

branches: 1.11.4;
Add COMPAT_BSDPTY on all the kernels that have COMPAT options.

IPv4 PIM support, based on a submission from Pavlin Radoslavov posted on
tech-net@

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

branches: 1.8.2;
add COMPAT_15/COMPAT_16

Bye Bye UCONSOLE

config says nsphy and ukphy are orphaned (nothing matching 'mii?' declared)
comment them out

Add one space between "#option" and "<tab>IPFILTER_DEFAULT_BLOCK"

Added (commented out) IPFILTER_DEFAULT_BLOCK.

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

branches: 1.2.2; 1.2.4;
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"

Example configuration for a system with a slow 68030 with limited RAM.
This was derived from the old SPOT config and is a cousin of the MYSTERY
