Adapt license to match FreeBSD's version, leaving Ed out
since according to CVS logs, he didn't touch NetBSD's version.
causes these tests to sometimes deadlock. Since they run really fast
when they are successful, it doesn't do any good to wait for the
default 5-minute timeout. So explicitly set timeout for these tests
to just 30 seconds.
The default retains the traditional NetBSD behavior, but the knob
can be set so that FreeBSD can retain their expected behavior.
This is a compromise to be sure.
Add a debug flag -dV to override the above, so that regardless of
the knob setting, the raw value of a variable can be easily seen.

abd userland, as proposed on tech-security, with explicit_bzero using
a volatile function pointer as suggested by Alan Barrett.
Both do what the name says. For userland, both are prefixed by "__"
to keep them out of the user namespace.
Change some memset/memcmp uses to the new functions where it makes
sense -- these are just some examples, more to come.
space in cpu_info instead. This also moves undefined_handler_address into
cpu_info as well.
Use the new armreg* inlines for getting TPIDRPRW register.
Add MULTIPROCESSOR version of CPU_INFO_FOREACH
On newer devices, when using the legacy TX descriptors, vlan-related flags
that were set on the last descriptor of a packet have to be set on the
first one.
For tso/checksum offloads, a new "advanced" descriptor format has to be
used.
Change wcd_txdescs to a union defining all types of descriptors (they
are all 16-bytes wide).
Define a new tx function wm_nq_start(), which handle newer devices.
There is some code duplication with wm_start(), but adding support to
the existing wm_start() would make it a if () {} else {} maze. This also
allows to get rid of some workaround for older chips that are not needed
here.
Use wm_nq_start() instead of wm_start() for the I350 (this should probably
be for all WM_F_NEWQUEUE devices, but I have no hardware but the I350 to
test). Call ifp->if_start() instead of wm_start() where is matters.
Tested on a I350, and a i80003 (which use the old format), both with and
without vlans, with and without checksum offloads.
Print only fatal error messages (i.e., when the database is left in
an inconsistent state and needs manual intervention).
