newfs_msdos: connect the ATF test from NetBSD

NetBSD has an ATF test for newfs_msdos. Connect it to the build.
Adapt it for FreeBSD. This would have caught the bug fixed by my
previous commit.

newfs_msdos: move mkfs_msdos to separate file for later use in makefs

Check in first src/tests snapshot from NetBSD anoncvs

Sources were obtained like so:

% export CVSROOT="anoncvs@anoncvs.NetBSD.org:/cvsroot"
% cvs -z9 co -D "09/30/2014 20:45" -P src/tests
% mv src/tests/* tests/dist/.

'*CVS*' has been added to svn:ignore to ease updating periodically from
upstream

Some line ending issues had to be resolved with test outputs and scripts
via dos2unix and by deleting the eol-style property set in usr.bin/sort

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

MFtbemd:

Prefer MACHNE_CPUARCH to MACHINE_ARCH in most contexts where you want
to test of all the CPUs of a given family conform.

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.

Bring back WARNS to 3 for arm until I figure out how to make gcc happy.

Oops... Remove the line leaked in the last commit which is not
intended to be there...

WARNS=6 cleanup:

- Initialize everything in the struct array, not only the mentioned
ones
- Unconditionally initialize hs to 0 to avoid repeatly doing so
- Cast to unsigned int when comparing to unsigned variables.

style.Makefile(5):
Use WARNS?= instead of WARNS=.

Additional PC98 option is not needed.

Default to WARNS=2.
Binary builds that cannot handle this must explicitly set WARNS=0.
