Restore Python 2.6+ compatibility

SVN r245536 ported this to Python 3. The major change was the use of the
print function. Unfortunately this is incompatible with Python 2, which
is still the default version in the ports tree.

Use a __future__ import to make this compatible with Python 2.6 and later.

Convert to Python 3

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.

Add a new tool which attempts to check for kernel configuration options that
are missing from NOTES files.
