The floppy test passes with this. The others fail due to 'integrity
checks' failing in GPART. It's not at all clear those integrity
checks are legit or if the test samples were bogusly generated
by FreeBSD.
These images are no longer relevant... However, I've also not tested
the regression test here to see if it still works or not... It needs
a lot of love regardless...
When using -S0, seed the PRNG with the current time in nanoseconds, not
seconds, so consecutive runs don't accidentally use the same seed.
Also, rename some variables for clarity.

The timespecadd(3) family of macros were imported from NetBSD back in
r35029. However, they were initially guarded by #ifdef _KERNEL. In the
meantime, we have grown at least 28 syscalls that use timespecs in some
way, leading many programs both inside and outside of the base system to
redefine those macros. It's better just to make the definitions public.
Our kernel currently defines two-argument versions of timespecadd and
timespecsub. NetBSD, OpenBSD, and FreeDesktop.org's libbsd, however, define
three-argument versions. Solaris also defines a three-argument version, but
only in its kernel. This revision changes our definition to match the
common three-argument version.
Bump _FreeBSD_version due to the breaking KPI change.

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Before this test just checked scenario of setting and removing the accept
filter at different states of the socket. Now it also checks that accept
filter works: we connect to the server, and then check that we can't accept,
then we send 1 byte of data and check again.
If the commands had failed previously, it would press on and result in a
series of cascading failures. Fail early and continue on to the next case
instead of executing additional commands after a previously failed series

sources to return timestamps when SO_TIMESTAMP is enabled. Two additional
clock sources are:
o nanosecond resolution realtime clock (equivalent of CLOCK_REALTIME);
o nanosecond resolution monotonic clock (equivalent of CLOCK_MONOTONIC).
In addition to this, this option provides unified interface to get bintime
(equivalent of using SO_BINTIME), except it also supported with IPv6 where
SO_BINTIME has never been supported. The long term plan is to depreciate
SO_BINTIME and move everything to using SO_TS_CLOCK.
Idea for this enhancement has been briefly discussed on the Net session
during dev summit in Ottawa last June and the general input was positive.
This change is believed to benefit network benchmarks/profiling as well
as other scenarios where precise time of arrival measurement is necessary.
There are two regression test cases as part of this commit: one extends unix
domain test code (unix_cmsg) to test new SCM_XXX types and another one
implementis totally new test case which exchanges UDP packets between two
processes using both conventional methods (i.e. calling clock_gettime(2)
before recv(2) and after send(2)), as well as using setsockopt()+recv() in
receive path. The resulting delays are checked for sanity for all supported
clock types.

They were not very useful in their current state. It only ran a fork bomb,
confirmed headers/footers matched, hard-coded the number of expected entries
(rather than ensuring each entry is present when expected), and was missing a
sizeof_long.c file from r251368 which makes its intent for testing 32-bit

More extensive tests should be written with ATF now.
After calling the cap_init(3) function Casper will fork from it's original
process, using pdfork(2). Forking from a process has a lot of advantages:
1. We have the same cwd as the original process.
2. The same uid, gid and groups.
3. The same MAC labels.
4. The same descriptor table.
5. The same routing table.
6. The same umask.
7. The same cpuset(1).
From now services are also in form of libraries.
We also removed libcapsicum at all and converts existing program using Casper

Although POSIX literally permits failing with [EINVAL] if IPC_CREAT and
IPC_EXCL were both passed, the semaphore set already exists and has fewer
semaphores than nsems, this does not allow an application to retry safely:
if the [EINVAL] is actually because of the semmsl limit, an infinite loop
would result.

the second set (increment the original ports by 10)
This avoids issues where the first listening socket might not be torn
down by the time it makes it to the second set of testcases.
The sockets should likely only be setup once, but this keeps in the
spirit of the original testcases, so this will be easier to backport
