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.

Bump WARNS where possible.

Commit 1 of 2 to fix ffsinfo(8) for UFS2.

Update ffsinfo(8) to use new UFS2 support in the growfs(8) debugging
functions. Largely consists of renaming fields and types to be aware
of the UFS1/UFS2 distinction, relying on libufs(3) to open and sanity
check the device/file/label accessed.

Since libufs(3) now handles label/UFS interactions, remove -L argument.

Note: when submitted, this patch had substantial style changes. I've
attempted to remove the restyling from the patch to separate the
functional and style changes.
