Convert files to UTF-8 and add some copyright markers where missing.

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.

Revert (once again, and hopefully for the last time) to flock(2) locks.
The problem with fcntl(2) locks is that they are not inherited by child
processes. This breaks pidfile(3), where the common idiom is to open
and lock the PID file before daemonizing.

Reimplement flopen(3) using fcntl(2) locks instead of flock(2) locks.

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

I'm tired of seeing this done incorrectly and non-portably, so add a
flopen(3) function which reliably opens and locks a file.
