m4: Add -G option which reverses -g.

This matches GNU m4's -G / --traditional option, and although BSD m4 in non-GNU mode is not exactly identical to GNU mode in traditional mode, it's close enough.

m4: Support long options.

The option names are identical to those of the equivalent options in GNU m4, except of course for --gnu which does not exist in GNU m4.

While here, make the argument to -d / --debug optional, with the same default behavior as in GNU m4, and document it properly.

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.
