With mac80211 operations (MO) tracing on we have seen some ill-ordered
executions of MO functions. In order to limit visibility of the mac80211
sta, pass the internal version into lkpi_80211_mo_sta_state() and only
there convert to the argument needed. This mostly eases tracing and
debugging.

When a breakpoint exception is raised, the saved value of %rip points to
the instruction following the breakpoint. However, when fetching the
value of %rip using regs[], it's more natural to provide the address of
the breakpoint itself, so modify the kinst and fbt providers accordingly.

There are known issues with unionfs, and the mount_unionfs man page has
a cautionary statement about its use. The caution had additional
"humourous" statements like "BEWARE OF DOG" but they served only to
confuse the situation. Remove them.

The suppresion was added in 5f311da2cc with no explanation in the
commit message of the exact problem that was fixed. In the BSDCan
2006 talk [1], slides 12 to 14, we can find that it seems that there
was some problem with the TIME_WAIT state not properly being handled
on the remote side (also FreeBSD!), and this switching off the
suppression had hidden the problem. The rationale of the change was
that other stacks may also be buggy wrt the TIME_WAIT.
I did not find the actual problem in TIME_WAIT that the suppression
has hidden, neither a commit that would fix it. However, since that
time we started to handle SYNs with RFC5961 instead of RFC793, see
3220a2121c. We also now have the tcp-testsuite [2], that has full
coverage of all possible scenarios of receiving SYN in TIME_WAIT.
This effectively reverts 5f311da2cc
and 6ee79c59d2.

The assertion was incorrectly removed in 0d7445193a. The leak of
a TIME-WAIT state into tfb_do_segment_nounlock method was fixed in

tcp_input() always.
This matches other mktemp implementations, including OpenBSD and GNU.
The -p option can be used to provide a tmpdir prefix for specified
templates. Precedence works out like so:
-t flag:
- $TMPDIR
- -p directory
- /tmp
Implied -t flag (no arguments or only -d flag):
- -p directory
- $TMPDIR
- /tmp
Some tests have been added for mktemp(1) in the process.

MODULES_OVERRIDE has traditionally taken precedence over EXTRA_MODULES
and WITHOUT_MODULES as the exact list of modules to build. Over time,
things have been added that has broken this. Move the .endif that makes
this the case to the right place. The so called 'ALL_MODULES' option is
the only thing with higher precedence, but it's not quite all the
options anymore (though it is much more of them, and doesn't quite
work on !x86).
