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.

Adjust _all_ cinclude of *.local files

- Ensure always at end
- Use tab rather than spaces
- Add consistent comment
"Pull in optional local configuration - always at end"

The only functional change is that a local file which tried to
override an existing setting (eg with "no foo") would have failed
in some cases before, but now will work

swwdog(4): Add to GENERIC kernels.

Plus a handful of others that I'm familiar with. Lots of special-
purpose kernels should probably have this too but I'm not going
through all the arm, mips, and ppc evaluation board kernels to see
which ones are relevant.

Omitted from systems I know to be very small:
- sun2/GENERIC
- dreamcast/GENERIC
Feel free to remove it from others that need to be kept smaller.

Compile-tested a few of these just in case:
- alpha/GENERIC
- amd64/GENERIC
- evbmips/OCTEON
- i386/GENERIC
- riscv/GENERIC

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.

enable a few more "generic" items in this configuration, mostly
from what pmax GENERIC enables, but not nearly all of it:

- enable OVERLAY, UMAPFS, FDESC, LFS, UNION, PUFFS (and putter),
and add some more commented out entries
- enable DISKLABEL_EI and FFS_EI
- turn on GATEWAY and ppp(4) options
- add commented ALTQ section

vether: Add to kernel configurations

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

evbmips: add ofctl(8) and /dev/openfirm support

ERLITE -> OCTEON

Add wedge support

Add USB3 support.

Add driver for Cavium Interrupt Bus.

Use uart0 for stdout-path

FDT support for Cavium OCTEON MIPS SoCs. WIP.

Rename the evbmips ERLITE kernel to OCTEON now that it supports more
than just the EdgeRouter Lite.
