Bring final version of libbind:

From
http://www.isc.org/downloads/libbind/

The libbind functions have been separated from the BIND suite as of BIND
9.6.0. Originally from older versions of BIND, they have been continually
maintained and improved but not installed by default with BIND 9. This
standard resolver library contains the same historical functions and
headers included with many Unix operating systems. In fact, most
implementations are based on the same original code.

At present, NetBSD maintains libbind code, now known as "netresolv".

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

- Import the HEAD csup code which is the basis for the cvsmode work.

Merge BIND 9.4.1 into main chunk.

MFC after: 2 weeks

Vendor import of BIND 9.4.1

Upgrade res_update(3) and the friends to BIND9's one excluding TSIG
support.

X-MFC after: never

Vendor import of BIND 9.3.2

Expose res_update and friends again. At least, ports/mail/spamilter
uses them.
Now, we have res_nupdate and res_nmkupdate as well, but they are
still based on our old resolver for binary backward compatibility.
So, they don't provide new features such as TSIG support.
