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 was prompted by noticing that '/var/db/portsnap' still exists on
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
administrators to delete it.

* In the setup phase, wait for the server to start (or fail to start)
before proceeding with the test. This makes it possible to write test
cases that don't expect a response from the server without ending up
in a race over the server PID file.
* After running each test, wait up to 30 seconds for the server to exit
and check that the exit status matches what the test case says to
expect (usually 0).
* We still kill and collect the server in the cleanup phase, in case the
test ended early.

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

- 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

Accept either little-endian or big-endian representation of the ELF
hints magic number in the header of a hints file and convert the
parameters to the native byte-order of the repsective system.
This is a pre-requisite for a planned change to always write the byte
order in little-endian format on all architectures. The only relvant
architecture that uses big-endian data is powerpc64, and it is not
likely that new architectures will choose that representation of data
in memory.
When all supported architectures use little-endian data in the hints
file, the byte swap logic can be enabled for big-endian CPUs at
compile time. Up to that point, there is a very small run-time penalty
that is paid on all systems to check the byte-order of the hints file
and to provide the option to byte-swap the parameters read from the
hints file header.

dlopen_basic just tests that libthr.so can be dlopen()ed, which will
just serve as a sanity check that "libthr.so" is a thing that can be
dlopened in case we get a weird failure in dlopen_recursing.
dlopen_recursing tests a regression reported after the libsys split,
where some dlopen() may cause infinite recursion and a resulting crash.
This case is inspired by bdrewery's description of what seemed to be
causing his issue.
The corresponding fix landed in commit

in addition to avoiding it for already loaded filtees. Issue is that
during load, rtld needs to resolve some special ABI symbols, like
executable stack fixer and static TLS initializer, which might trigger
recursion.
Example is libthr which is filter for libsys, and which exports
__pthread_distribute_static_tls.

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.
