Remove $FreeBSD$: one-line sh pattern

pkgbase: Put geom utilities in their own package

For most users it's not needed to boot and they are also
available in the FreeBSD-rescue package in case an update
break and FreeBSD-geom package isn't updated correctly.

Only set WARNS if not defined

This would allow interested parties to do experimental runs with an
environment set appropriately to raise all the warnings throughout the
build; e.g. env WARNS=6 NO_WERROR=yes buildworld.

Not currently touching the numerous instances in ^/tools.

gvinum: revert WARNS change in Makefile

Architectures that passed on a local build universe, failed on
tinderbox. Revert the number change for now while I investigate.

gvinum: build with WARNS=6

This also removes an unused and uninitialized variable.

Tested with amd64, arm64, i386, mips

Utilize SYSROOT from r320119 in places where DESTDIR may be wanting WORLDTMP.

Since buildenv exports SYSROOT all of these uses will now look in
WORLDTMP by default.

A LIBSTAND hack is no longer required for buildenv.

Convert sbin/ to LIBADD
Reduce overlinking

Replace all uses of libncurses and libtermcap with their wide character
variants. This allows usable file system images (i.e. those with both a
shell and an editor) to be created with only one copy of the curses library.

Don't overwrite the global default CFLAGS when setting include paths.

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.

Switch the default WARNS level for sbin/ to 6.

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

Finally bring in what was produced during Google SoC 2005:

Add functions to rename objects and to move a subdisk from one drive
to another.

Add manual page (finally).

Bring up-to-date the online help.

For variables that are only checked with defined(), don't provide
any fake value.

Add gvinum, the geom_vinum userland tool.
