No functional change intended.

Add linux POSIX message queue support (Ricardo Branco)

new inotify support GSoC 2023 (Theodore Preduta)

Add a NetBSD native futex implementation, mostly written by riastradh@.
Map the COMPAT_LINUX futex calls to the native ones.

Merge changes from current as of 20200406

Deal with having to teardown sysctl entries in multiple sub-trees.

(This used to work, but I broke it recently.)

Use the module subsystem's ability to process SYSCTL_SETUP() entries to
automate installation of sysctl nodes.

Note that there are still a number of device and pseudo-device modules
that create entries tied to individual device units, rather than to the
module itself.  These are not changed.

Merge the [pgoyette-compat] branch

Reduce the list of required modules to what is really needed

Add a few more references to the (currently always but not forever)
built-in compat_util module

Remove leading coma from list of required modules.  It doesn't seem
to cause any real problems, but it makes modstat output look weird.

Adjust module requirements to reflect the new more granular modules

Finally (hopefully) return completely to the state where compat_linux is
enabled by default.

While here make it possible to enable this if already enabled, or disable
if already disabled, without error.   Some minor KNF.

Finish the previous change - as well as setting the default for these
compat modules back to enabled, stop forcing it to switch back to
disabled any time the module is init'd (which is truly barbaric behaviour.)

update from HEAD

Unbreak Linux emulation by default. While not loading it automatically
is somewhat sensible, breaking functionality of GENERIC is not and has
been objected to on a regular base.

Remove compat_linux from the autoload list, and add a sysctl to enable or
disable it - which defaults to disabled. The following command is now
required to use linux binaries:

	sysctl -w emul.linux.enabled=1

After a discussion on tech-kern@. All the other ideas to reduce the attack
surface have drawbacks, and this sysctl seems to be the best option.

Sync with HEAD (as of 26th Dec)

Merge the compat_sysv module into the sysv_ipc module - it should
never have been a separate module in the first place (my bad).

Adjust dependencies as appropriate.

Revert ticket #1020, per pgoyette in ticket #1041.

Add an additional dependency on compat_sysv
Add another dependency for nfsserver
And yet another dependency, this time on mq
Ooops, spell the module name in full. "mqueue" vs "mq"
we need compat_sysv now.

c99 initializers for struct execsw

exec modules need to be of the exec kind

Can't use RUN_ONCE here to initialize the futex_lock, otherwise we cannot
unload the module.

Make the emulations, exec formats, coredump, NFS, and the NFS server
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime
