- [1] Make the driver friendly towards kernel without PREEMPTION.
Use msleep(9) instead of simple unlock-check_variable-lock mechanisme
since the later not really effective in non-preemptible kernel
(especially during codec detection routine).
- Free most driver resources in a sane manner to avoid possible
double free and panics especially during device detach and codec
detection failure.

In particular, this fixes the problem where tar -xp always returned
a failure code on FreeBSD (which doesn't yet have all of the extended
attribute support).

Specifically, on mappings with PG_G set pmap_remove() not only performs
the necessary per-page invlpg invalidations but also performs an
unnecessary invalidation of the entire set of non-PG_G entries.

forthcoming. This commit also has a number of style(9) fixes and
minor corrections so the code works better with the build system being
used for non-FreeBSD builds.
Many thanks to: Jaakko Heinonen, who proposed a mechanism for extended
attribute support and implemented both the machine-independent portion
and the Linux-specific portion.
This commit implements storing/reading POSIX.1e-style extended
attribute information in "pax" format archives. An outline of the
storage format is in the tar.5 manpage. The archive_read_extract()
function has code to restore those archives to disk for Linux; FreeBSD
implementation is forthcoming.
Many thanks to Jaakko Heinonen for finding flaws in earlier
proposals and doing the bulk of the coding in this work.
Since, res_sendsigned(3) and the friends use MD5 functions, it is
hard to include them without having MD5 functions in libc. So,
res_sendsigned(3) is not merged into libc.
Since, res_update(3) in BIND9 is not binary compatible with our
res_update(3), res_update(3) is leaved as is, except some
necessary modifications.
The res_update(3) and the friends are not essential part of the
resolver. They are not defined in resolv.h but defined in
res_update.h separately in BIND9. Further, they are not called from
our tree. So, I hide them from our resolv.h, but leave them only
for binary backward compatibility (perhaps, no one calls them).
Since, struct __res_state_ext is not exposed in BIND9, I hide it
from our resolv.h. And, global variable _res_ext is removed. It
breaks binary backward compatibility. But, since it is not used from
outside of our libc, I think it is safe.

multicast addresses from carp interface. [1]
o Rewrite carpdetach(), so that it does the following things: [1]
- Stops callouts.
- Decrements carp_suppress_preempt, if needed.
- Downs interface and sets CARP state to INIT.
- Calls carp_multicast_cleanup().
- Detaches softc from carp_if and if we are the last frees
the carp_if.
o Use new carpdetach() in carp_clone_destroy().
o In carp_ifdetach() acquire the carp_if lock and cleanup all
interfaces hanging on carp_if. [1]
o Make carp_ifdetach() static and use EVENT(9) to call it
from if_detach(). [2]
o In carp_setrun() exit if the softc doesn't have a valid pointer
to parent. [1]
