ncurses: split libtinfo from libncurses

many external program expects libncurses to not be provided as a single
library. Instead of fixing all ports, distribute ncurses the way
upstream distributes it

Turn libncursesw.so into a ldscript which will link automatically as
needed to libtinfow so so this change is seamless at compile time.

ncurses: only keep the version with widechar support

Only keep the widechar version of ncurses as libncursesw.so.9

Keep the old name to avoid breaking the ABI compatibility (the non
widechar version libncurses.so.9 is not binary compatible with
libncursesw.so.9) since all ports and base are already only linking
against the widechar version we can simply remove libncurses.so.9

Since the .9 version only lived in the dev branch and never ended in a
release, it is simply removed and not added to any binary compat
package.

Add symlinks to keep build time compatibility for anyone linking against
-lncurses

Revert r261296. This removes the WITHOUT_NCURSESW option.

It was the wrong direction. We will instead remove use of the
non-wide-character supporting libncurses.

Use src.opts.mk in preference to bsd.own.mk except where we need stuff
from the latter.

Add an option WITHOUT_NCURSESW to suppress building and linking to
libncursesw. While wide character support it useful we'd like to
only need one ncurses library on embedded systems.

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.
