in FreeBSD 7 that has not been used since. It contains a number
of unresolved bugs including an inverted bcopy() and incorrect
handling of read-only mbufs using internal storage. Removing this
unused code is substantially essier than fixing it in order to
update it to the coming mbuf world order -- but it can always be
restored from revision history if it turns out to prove useful for
future work.

r273087. Move all checks from gif_output() into gif_transmit(). Previously
they were checked always, because if_start always called gif_output.
Now gif_transmit() can be called directly from if_bridge() code and we need
do checks here.

libc, or don't exist. Remove these from the build. Some of these may
return later on specific targets.

There are a number of msdosfs improvements in NetBSD that may be worth
bringing over, and this reduces noise in the comparison.

handle it in arc_output() instead of nd6_storelladdr().
* Remove IFT_ARCNET check from arpresolve() since arc_output() does not
use arpresolve() to handle broadcast/multicast. This check was there
since r84931. It looks like it was not used since r89099 (initial
import of Arcnet support where multicast is handled separately).
* Remove IFT_IEEE1394 case from nd6_storelladdr() since firewire_output()
calles nd6_storelladdr() for unicast addresses only.
* Remove IFT_ARCNET case from nd6_storelladdr() since arc_output() now
handles multicast by itself.
As a result, we have the following pattern: all non-ethernet-style
media have their own multicast map handling inside their appropriate
routines. On the other hand, arpresolve() (and nd6_storelladdr()) which
meant to be 'generic' ones de-facto handles ethernet-only multicast maps.

decade: m_pulldown() is willing to consider ordinary mbufs writable.
Retain another, related, and also outdated comment, but with a caveat
that it is partially stale. Do not, for now, address the problem that
it raises (that only EXT_CLUSTER external storage is considered
writable, regardless of the results of M_WRITABLE() on the mbuf).

sanitizer libraries that already work on FreeBSD:

* ubsan: Undefined Behavior Sanitizer
* profile: Profile Guided Optimization support
Please note that these libraries are *experimental* at this stage, so
the main Makefile is not yet connected to the build.
Since I didn't want to needlessly edit BSD.usr.dist, you will also have
to create the install directory /usr/lib/clang/3.5.0/lib/freebsd

EOPNOTSUPP. The current behavior can mask real quiesce errors since
devclass_quiesce_driver() stops iterating over drivers as soon as it
gets an error (incluiding EOPNOTSUPP), but the caller it returns the
error to explicitly ignores EOPNOTSUPP.
