Add some sanity checks when service jails are used in jails:
- children.max > 0
- children.max - children.cur > 0
The nesting is too deep at those places to have a sane formatting, so no
line wrapping at the usual column.
If someone has a better idea how to format this: feel free to go ahead.
Clarify that the "sysvipc" svcj option inherits from the host / parent.
Add "sysvipcnew" which creates a new SysV namespace for the service
jail.
Sanity check that only one of them is used.
This clarifies the code and makes it less error-prone. It also makes it
easier to extend downstream in CheriBSD (where pointer and integer
members no longer have the same representation and an additional member
is present).

New variable ${name}_offcmd may be used to supply commands
executed if named service is not enabled. Previously start_precmd
could be used for such a task but now rc.subr(8) does not call it
if a service is not enabled.
Fix devd startup script to use it instead of start_precmd.

At the moment, if bootrace profiling is enabled, autoboot is not

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
root-path as the host (or parent jail) and may inherit the network from
the host (or parent jail). Per service there is the possibility to
specify some arguments which give more permissions (e.g. netv4, netv6,
sysvipc...).

GCC 13 complains that we might be writing too much to an on-stack buffer
when createing a filename.
In practice there is a check that filename isn't too long given the
time format and other static characters so GCC is incorrect, but GCC
isn't wrong that we're potentially trying to put a MAXPATHLEN length
string + some other characters into a MAXPATHLEN buffer (if you ignore
the check GCC can't realistically evaluate at compile time).
Switch to snprintf to populate filename to ensure that future logic
errors don't result in a stack overflow.
Shorten the questionably named yyyymmdd buffer enough to slience the
warning (checking the snprintf return value isn't sufficent) while
preserving maximum flexibility for admins who use the -F option.

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.

newly-installed machines.
With this change, all mentions of portsnap(8) in the tree are gone,
except for the historical note in the AUTHORS section of manpage
phttpget(8).
locate(1) will thus start indexing again '/var/db/portsnap' on machines
where this directory still exists, which may be a good way to push

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.
