Fix I/O leakage. We're cloning bios in g_stripe_start_fast(), but when
something goes wrong while running in "fast" mode, we free all bios and
falling back to "economic" mode. Freeing bios, doesn't mean decrease
bio_children, so bio_inbed couldn't be equal to bio_children and request
was never finished.
Decrease bio_children manually when destroying bios.

Improve geom(8)'s 'list' command to show geoms and their providers and
consumers. Teach STRIPE, CONCAT and NOP classes about this improvement.

Implement "FAST" mode for GEOM_STRIPE class and turn it on by default.
In this mode you can setup even very small stripe size and you can be
sure that only one I/O request will be send to every disks in stripe.
It consumes some more memory, but if allocation fails, it will fall
back to "ECONOMIC" mode.
It is about 10 times faster for small stripe size than "ECONOMIC" mode
and other RAID0 implementations. It is even recommended to use this
mode and small stripe size, so our requests are always splitted.
One can still use "ECONOMIC" mode by setting kern.geom.stripe.fast to 0.
It is also possible to setup maximum memory which "FAST" mode can consume,
by setting kern.geom.stripe.maxmem from /boot/loader.conf.

less dangerous.
- Update manual pages and extend examples.
- Bump versions.

Introduce STRIPE GEOM class. It implements RAID0 transformation and it
is intend to be fast. Just like CONCAT class it provides manual and
auto configuration methods.
