32bdc2b685 Use expand_number(3) from libutil instead of home-grown function to parse
human-friendly power-of-two numbers (i.e. 2k, 5M etc).

64c8fef580 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.

fc903aa525 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.

5a29754e3f Back out conversion to libufs, for now. It seems to cause problems.

9d492cddac Convert newfs to use libufs. I've tested this on md filesystems, as has
keramida, and all seems well.

89fb8ee796 Add the undocumented -R option to disable randomness for regression-testing.
Add a couple of simple regression tests accessible with "make test", they
depend on the md(4) driver.

FYI I have also tried running the test against a week old newfs and it
passed.

f7b48c89c8 The FSIRAND code is always compiled in, and it is unlikely that
anyone needs a newfs without it. Remove the #ifdef's from around
the code and the -DFSIRAND from the Makefile. Also remove redundant
declarations of random() and srandomdev().

0 was bad and setting it unconditionally to 2 was worse.

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