Allow Debug{On,Off} to run associated hooks.
This makes it feasible to collect extra debug info at runtime
without needing to modify any potentially verified and hence immutable
scripts.
Like debug.sh, hooks.sh is extremely handy and used extensively
in many parts of Junos and its build environment.
It is provided here in the hope that others may benefit.
We do not dot hooks.sh by default to reduce overhead, but it can
but done from rc.conf et al using
$_HOOKS_SH . /libexec/hooks.sh

Reload is used for service reconfiguration as well
and lacks a NAME_prepend-like mechanism so it makes
sense to extend the NAME_reload hook into this
action.
precmd may use configuration checks and blocks setup
from doing its designated work (e.g. nginx). In moving
the invoke of the setup script in front allows us to
provide custom scripts for config file generation and
fixing prior to precmd checking configuration integrity.
Also introduce _run_rc_setup to separate the launcher
from the main one. Let it run correctly in the case
of restart_precmd and block further execution as
would be the case in start due to the internal plumbing
of restart being split into calling stop and start
afterwards.

This gives more permissions to services (e.g. network access to
services which require this) when they are started as an automatic
service jail.
The sshd patch is important for the sshd-related functionality as
described in the man-page in the service jails part.
The location of the added env vars is supposed to allow overriding them
in rc.conf, and to hard-disable the use of svcj for some parts where it
doesn't make sense or will not work.
Only a subset of all of the services are fully tested (I'm running this
since more than a year with various services started as service jails).
The untested parts should be most of the time ok, in some edge-cases
more permissions are needed inside the service jail.

This takes a rc.d-service and starts it in a jail which shares the same

Introduce hw.bus.devctl_nomatch_enabled and use it to suppress NOMATCH
until devmatch runs
There's a lot of NOMATCH events generated at boot. We also run devmatch
once during early boot to load unmatched devices. To avoid redundant
work, don't start generating NOMATCH events until after devmatch runs.
Set hw.bus.devctl_nomatch_enabled=1 just before we run devmatch. The
kernel will suppress NOMATCH events until this is set to true.
This saves about 170ms from the boot on aarch64 running atop Apple
M-series processors and the VMWare Fusion hypervisor.

This setting causes the NFS server to check that all RPCs are sent from
a privileged (<= 1023) port, rejecting those that are not. This
slightly raises the bar for a user with network access to an
unauthenticated NFS server to access exported NFS filesystems.
Users that use traditional NFS clients (e.g., those provided by FreeBSD
or Linux) should not see any difference, assuming that unprivileged
filesystem mounting is disallowed.
Note that the setting is per-VNET, so may be overridden in VNET jails
without affecting the rest of the system.

The following features are currently supported:
- adding users (including a default user named 'freebsd' with password
'freebsd'
- adding groups
- adding ssh keys
- static ipv4, static ipv6, dynamic ipv4
With this one is able to use the 'bring your own image feature" out of

basename, sed and tty are all in /usr/bin and not available

basename and tty we can replace with a function, but sed is more
important. Fix o_verify to just use shell builtins, and
rc_trace should avoid trying to set RC_LEVEL until sed is available.
Debugging boot issues can be helped by
logging each rc.d script as it is run
and being able to selectively enable/disable set -x
debug.sh provides an elaborate framework for debugging shell scripts.
For secure systems, we want to be paranoid about what we read
during boot.
dot() simply reads (.) arg file if it exists
vdot() if mac_veriexec is active, ignore unverified files
otherwise behaves much the same as dot()
safe_dot() in safe_eval.sh allows reading an untrusted file;
limiting the input to simple variable assignments.
In load_rc_config allow caller to provide an option to indicate how to
handle its arg:
-v use vdot()
-s use sdot() which will try to use vdot() and fallback to safe_dot()
The default is to read using dot()
rc_run_scripts()
encapsulate the running of rc.d scripts
so that we can easily call it more than twice.
We vdot local.rc.subr to pick up extensions (like
run_rc_scripts_final) and overrides.
We also allow rc.subr.local or rc.conf to set rc_config_xtra
eg (rc_config_xtra=XXX for historic compatibility)
rc use set -o verify around the reading in of rc.subr
This has no effect if mac_veriexec is not active, but if it is; ensures
rc.subr has not been tampered with.
