libc: Fix C23 version macro visibility
In headers that existed prior to C23, these should be visible only in
C23 or BSD mode.
Fixes: 0fe73dcf7c32 ("libc: Add <assert.h> C23 feature test macro")
Fixes: 1f09e354297c ("sys/limits.h: Add BOOL_MAX, BITINT_MAXWIDTH, and C23 feature test macro")
Fixes: cd0727ec709b ("libc: Add <stdio.h> C23 feature test macro")
Fixes: fc9d02cb29ed ("libc: Add <time.h> C23 feature test macro")
Fixes: 4aeed6e9d213 ("libc: Add <setjmp.h> C23 feature test macro")

rc.subr tests: service jail behaviour of run_rc_command
Twenty cases over where each rc option and each method executes for a
jailed service, the jail's lifetime, and the svcj option handling. Each
case drives the service inside a chroot built in its ATF work directory.

rc.conf.5: note that a negative nice value does not reach a service jail
Raising a process' priority is not permitted inside a jail, and nice(1)
warns and executes the command anyway, so the service comes up at its login
class priority.
Not changing the date, as a commit a moment before this, one changed it
already.

rc.subr: svcj - add a setaudit option
setaudit(8) is prefixed to the command inside the jail when
${name}_audit_user is set, and needs allow.setaudit.
This is not added automatically when ${name}_audit_user is set, this
needs an administrative setting of the options on purpose.

rc.subr: svcj - run a service's own restart and status methods in its jail
A script that defines non-default restart_cmd or status_cmd should
execute them in the service jail. Where there is no jail to enter,
restart starts the service instead of failing.

rc.subr: svcj - remove the service jail when the service is not running
A service whose tracked process had died while another process of its own
kept the jail alive, therefore left svcj-${name} behind, and the next start
would fail.

rc.subr: svcj - send the stop signal from inside the service jail
A service running under ${name}_user was signalled from the host as that
user, which the parent of a jail may no longer do: since 8a5ceebece03 an
unprivileged process would need allow.unprivileged_parent_tampering.
Stop and reload therefore failed and left both the service and its jail
running.
