Remove $FreeBSD$: one-line .c comment pattern

Remove /^/[*/]\s*\$FreeBSD\$.*\n/

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.

Do not pull in <sys/select.h>, it isn't required.

The tcl/perl interpreter compile options were not really optional.

This is needed for building the boot crunch for 2.2 (It still needs a hook
so the release code can tell it when to build it without tcl etc).

Update to use nvi-1.79 sources
