pkgbase: Put chio in utilities

No need to bloat runtime with this utility.

Differential Revision: https://reviews.freebsd.org/D30753

Explicitly add unmarked bin/ binaries to the runtime package.
Note: tcsh(1) has a MK_TCSH=no test, so this should be a separate
package, which requires pre-install/post-install scripts, to be
added later.

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.

Changes from OpenBSD:
* Better usage() - correct syntax, display available commands
instead of examples
* Accept command abbreviations
* sprintf -> snprintf (for paranoia)
* manpage capitalisation tweak

Updated the ch(4) driver and chio(1) command to include volume
tag support. These changes have been tested with a Breeze Hill
Q47 DLT and a DEC DLT2500 media changer. The latter has no
volume tag support.

The chio(1) command was updated to include various flags to the
status subcommand. These flags can be used to select additional
information to be displayed (like volume tags).

A new chio(1) subcommand named 'voltag' has been added which allows
for changes to volume tags inside the media changer controller.
This could not be tested as the Q47 does not provide the functio-
nality.

This command doesn't need to be setuid root, it's only asking
for potential trouble.
