adduser(8): support creation of ZFS dataset

On systems utilizing ZFS, default to creating a ZFS dataset for a new
user's home directory if the parent directory resides on a ZFS dataset.
Add a flag that disables this behavior if the administrator explicitly
does not want it.

If run during installation from within a chroot, set mountpoint to legacy
after dataset creation and mount directly into the chroot. Then umount
and reset the mountpoint to inherit from parent.

Also support ZFS default encryption on user's home directory.

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.
