pkgbase: Put ufs related tools and lib in their own package

It's not really useful in a jail or in a mdroot or even if a users
wants to do a full zfs machine.

'*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

Update to current version of head.

IFH@204581

Use expand_number(3) from libutil instead of home-grown function to parse
human-friendly power-of-two numbers (i.e. 2k, 5M etc).

Enable operation of newfs on plain files, which is useful when you
want to prepare disk images for emulators (though 'makefs' in port
can do something similar).

This relies on:
+ minor changes to pass the consistency checks even when working on a file;

+ an additional option, '-p partition' , to specify the disk partition to
initialize;

+ some changes on the I/O routines to deal with partition offsets.

The latter was a bit tricky to implement, see the details in newfs.h:
in newfs, I/O is done through libufs which assumes that the file
descriptor refers to the whole partition. Introducing support for
the offset in libufs would require a non-backward compatible change
in the library, to be dealt with a version bump or with symbol
versioning.

I felt both approaches to be overkill for this specific application,
especially because there might be other changes to libufs that might
become necessary in the near future.

So I used the following trick:
- read access is always done by calling bread() directly, so we just add
the offset in the (few) places that call bread();
- write access is done through bwrite() and sbwrite(), which in turn
calls bwrite(). To avoid rewriting sbwrite(), we supply our own version
of bwrite() here, which takes precedence over the version in libufs.

Convert newfs to libufs (really). Solves one real issue with previous
version of such. Differences in filesystems generated were found to be
from 1) sbwrite with the "all" parameter 2) removal of writecache. The
sbwrite call was made to perform as the original version, and otherwise
this was checked against a version of newfs with the write cache removed.

Back out conversion to libufs, for now. It seems to cause problems.

Convert newfs to use libufs. I've tested this on md filesystems, as has
keramida, and all seems well.

Removed vestiges of mount_mfs. Sorted the Makefile a bit.

Fixed 2 layers of breakage of WARNS. Setting WARNS unconditionally to
0 was bad and setting it unconditionally to 2 was worse.
