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.

Add optoion GENERIC.local include to the end of ~all GENERIC configs

This excludes atari, sgimips, evbmips, evbppc, evbsh3, and hpcarm
all of which have somewhat specific kernel config file layouts

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.

Add commented-out ep(4) at pcmcia(4); it works just fine now.

Unreference IPF/PF from all the config files, and enable NPF instead when

Remove unused extended attributes kernel options

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART
and UFS_EXTATTR_AUTOCREATE are not used anywhere in the code. Remove them
as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr
LFS_EXTATTR_AUTOSTART was created to match obsolete UFS_EXTATTR_AUTOSTART
UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate

Support for UFS1 extended attributes in GENERIC and GENERIC-like kernels

This change just brings UFS1 extended attribute *support* in the kernel,
extended attributes are not enabled unless three conditions are met:
1) filesystem is UFS1 (newfs -O1)
2) .attribute/system and .attribute/user directories are created at fs root
3) filesystem is mounted with -o extattr

Some GENERIC kernels are obviously memory constrained, the extended
attributes options were not enabled for them, but just added commented out.
(kernel were considered memory constrained if QUOTA option was disabled)

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.

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

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

Initial addition of tmpfs, an efficient memory file-system. This project
was developed as part of Google's Summer of Code 2005 program. This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.

The file-system is still *experimental*. Therefore, it is disabled by
default in all kernels. However, as typically done, a commented-out
entry is added in them to ease its setup.

Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable
and because, before enabling it, I'd like to do some other changes.

OK'ed by my project mentor, William Studenmund (wrstuden@).
