In the CheriBSD CI we reproducibly see the first test in sys/audit
(administrative:acct_failure) fail due to a missing startup message.
It appears this is caused by a race condition when starting auditd:
`service auditd onestart` returns as soon as the initial auditd() parent
exits (after the daemon(3) call).
We can avoid this problem by setting up the auditd infrastructure
in-process: libauditd contains audit_quick_{start,stop}() functions that
look like they are ideally suited to this task.
This patch also avoids forking lots of shell processes for each of the 418
tests by using `auditon(A_SENDTRIGGER, &trigger, sizeof(trigger))` to check
for a running auditd(8) instead of using `service auditd onestatus`.
With these two changes (and D28388 to fix the XFAIL'd test) I can now
boot and run `cd /usr/tests/sys/audit && kyua test` without any failures
in a single-core QEMU instance. Before there would always be at least one
failed test.
Besides making the tests more reliable in CI, a nice side-effect of this
change is that it also significantly speeds up running them by avoiding
lots of fork()/execve() caused by shell scripts:
Running kyua test on an AArch64 QEMU took 315s before and now takes 68s,
so it's roughly 3.5 times faster. This effect is even larger when running
on a CHERI-RISC-V QEMU since emulating CHERI instructions on an x86 host
is noticeably slower than emulating AArch64.
Test Plan: aarch64+amd64 QEMU no longer fail.

FreeBSD
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
