bb27d7ed90 Add a way to specify stripesize and stripeoffset to gnop(8). This makes 
it possible to "simulate" 4K media, to eg test alignment handling.

df3d5a19fc Teach NOP GEOM class how to gather the following statistics: 
- number of read I/O requests,
- number of write I/O requests,
- number of read bytes,
- number of written bytes.
Add 'reset' subcommand for resetting statistics.

d5c96d389e - Add '-S' option, which allow to specify sector size for transparent 
provider.
- Bump version number.

This allows for a quite interesting trick. One can setup a stripe with
stripe size of 512 bytes and create transparent provider on top of it
with sector size equal to <ndisks> * 512. The result will be something
like RAID3 without parity disk (every access will touch all disks).
