Update share/examples/* to properly install /usr/share/examples.

As result of this, a new examples package is now created.

Note, this is only effective with 'SHARED=copies' (the default),
as the 'SHARED=symlinks' mechanism will create a symlink to the
source tree version of the file(s).

Rework META_TARGETS so that it automatically adds META_DEPS to the targets.

This will only be done if the target is defined, so if the target is
defined after bsd.sys.mk is included then it needs to manually add
${META_DEPS} still.

META_MODE: Simplify the META_COOKIE handling to use .USE/.USEBEFORE.

Extend it to other cases of meta mode cookies so they get the proper rm
cookie behavior when a .meta file detects it needs to rebuild and fails.

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.

For variables that are only checked with defined(), don't provide

Remove MAINTAINER= lines from individual Makefiles in favor of the
MAINTAINER file (which already had entries for sendmail).

Prevent a 'make SHARED=symlinks install' followed by 'make install' from
failing by removing the symlink before trying to install the actual files.

Unbreak installworld. Revision 1.41 of src/usr.bin/xinstall/xinstall.c
made the usage here incorrect.

Note that the change to install may cause other things to break, such as
the advice in src/etc/defaults/make.conf:

# Compare before install
#INSTALL=install -C

If users actually use this, any ${INSTALL} -d invocations in an installworld
will also fail.
