Return a NUL string instead of just working by accident with kvm_geterr(3)
when MALLOC_PRODUCTION is disabled (I didn't confirm the MALLOC_PRODUCTION
being enabled path).
Document the new explicit return behavior for kvm_geterr(3), as well
as the previous implicit behavior, i.e., the buffer attached to
returned via kvm_geterr(3) would be empty if a previous error hadn't been
stored in `kd`.

We must ensure there's space for the terminating null in the temporary
buffer in imgact_binmisc_populate_interp().
Note that there's no buffer overflow here because xbe->xbe_interpreter's
length and null termination is checked in imgact_binmisc_add_entry()
before imgact_binmisc_populate_interp() is called. However, the latter
should correctly enforce its own bounds.

Let firmware do its best first, and if it can't, try software recovery.
I would remove software timeout handler completely, but found bunch of
complains on command timeout on sparc64 mailing list few years ago, so
better be safe in case of interrupt loss.

For three years now CAM does not use SIM lock, but still enforces SIM to
use it. Remove this requirement, allowing SIMs to have any locking they
prefer, if they pass no mutex to cam_sim_alloc().

This is a painful change, but it is needed. On the one hand, we avoid
modifying them, and this slows down some ideas, on the other hand we still
eventually modify them and tools like netstat(1) never work on next version of
FreeBSD. We maintain a ton of spares in them, and we already got some ifdef
hell at the end of tcpcb.
Details:
- Hide struct inpcb, struct tcpcb under _KERNEL || _WANT_FOO.
- Make struct xinpcb, struct xtcpcb pure API structures, not including
kernel structures inpcb and tcpcb inside. Export into these structures
the fields from inpcb and tcpcb that are known to be used, and put there
a ton of spare space.
- Make kernel and userland utilities compilable after these changes.
- Bump __FreeBSD_version.

This test was failing if run twice because rtadvd takes too long to die.
The rtadvd process from the first run was still running when the
second run created its interfaces. The solution is to use SIGKILL during
the cleanup instead of SIGTERM so rtadvd will die faster.
While I'm here, randomize the addresses used for the test, which makes bugs
like this easier to spot, and fix the cleanup order to be the opposite of
the setup order

- Check the return from a call to malloc() in skim_printcap(), and
return a NULL if that fails.
- Fix a small memory leak in main() that happens if skim_printcap()
returns an error, including the new error-return of NULL.

Since the uset can set dhcp.interface-mtu, we need to try to validate the
value. So we verify if the conversion to int is successful and we will not
allow to set value greater than max IPv4 packet size.
Also use snprintf for safety.
