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.

946e2f3595 - Remove gc_argname field. It was introduced for gpart(8), but if I 
understand everything correctly, we don't really need it.
- Provide default numeric value as strings. This allows to simplify
  a lot of code.
- Bump version number.

3cf55d3ab9 Add gpart(8). 
In order to support gpart(8), geom(8) needs to support a named
argument. Also, optional string parameters are a requirement.
Both have been added to the infrastructure. The former required
all existing classes to be adjusted.

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).

e370e911b2 MFp4: Add two options for gnop(8)'s 'create' command: 
-o offset - specifies where to start on the original provider
	-s size - specifies size of the transparent provider

a158e237fc Introduce geom(8)-specific shared libraries for CONCAT, STRIPE and NOP 
GEOM classes. CONCAT should be 100% compatible with existing gconcat(8)
utility, which is going to be removed.
