All new benchmarks, old ones removed

dd.ru is a rackup file is intended as a dd(1)-like test for I/O
performance.

There are also individual request, response, and big_request
benchmarks for micro benchmarking some parts of Unicorn.

The rest of the benchmarks are gone: I am not interested in
performance comparisons (and pissing matches) with other web
servers (or their fanboys/girls).

I will _NEVER_ publically publish benchmarks comparing Unicorn
against other web servers.  I will only compare Unicorn against
other versions of Unicorn, possibly on different platforms.

Neutral third-parties are invited to publish their own
benchmarks (along with detailed procedures, version numbers and
other details) comparing Unicorn to other servers.
