[haiku-development] mkfs utility for haiku

Hello.
This is a new CL file system initialization utility for haiku. It use
the new device interface.
This is only a first version and I will be happy to improve it with
your feedback.
Actually It initializes only BFS Volume but as soon as other
initialization routines are written I will do the necessary changes.
The syntax is quite simple:
$ mkfs -t bfs [-v] -o <FsOptions> <DeviceName> <VolumeName>
Cheers,
Marco
