Remove $FreeBSD$: one-line sh pattern

Remove /^\s*#[#!]?\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.

Shift+Ins - paste buffer
Shift+PrintScr - prev. screen

Add FreeBSD ID tags while I'm here, since people often copy an exiting
keyboard map and then edit that and try to commit it.

- Fix errors in some keymap files.

- The numpad * key should always generate *.
- The numpad - is fkey52 and should not generate a control code (0x1f).
- The numpad 5 is fkey54, not fkey61.
- The numpad 6 is fkey55 and should not generate a control code (0x1e).

- Fix Spanish keymap.

NOTE: us.unix.kbd and us.emacs.kbd are very much different from the
other keymaps, thus, I didn't touch them.

The control code ^_ (0x1f) should really be called `us' rather than `ns'.

- Correct inconsistencies among keymaps.
- define CTL-ALT-ESC as `debug' key in all keymaps. (FAQ mentions this
key sequence but not all keymaps had it!)
- define CTL-SPACE as NUL in all keymaps.
- define CTL-ALT-SPACE as `suspend' key in all but Russiun keymaps.
- Fix Japanese keymaps. Some CTL- keystrokes were wrong.
- Remove accent (dead) key definitions from spanish.iso.kbd,
fr.iso.kbd and icelandic.iso.kbd. Create spanish.iso.acc.kbd,
fr.iso.acc.kbd and icelandic.iso.acc.kbd with accent key definitions
instead.
- Update INDEX.keymaps and Makefile.

Fix the bug that caused switch to ttyv02 when pressing the numpad enter.

Dvorak keyboard users of the world unite!

us.dvorak.kbd: The "standard" (note the quotes, there really isn't any
standard for non-alphanumeric keys in the Dvorak
world) version, identical to what MicroSoft
distributes in their DOS-6.22 supplementary disk.
us.dvorakx.kbd: The version I use, three pairs swapped (esc <-> `~,
clock <-> lctrl, and =+ <-> \|) from the above.
