Title: Debian iostat support

The version of `iostat` on Debian testing adds two additional fields to iostat -x output: `r_await` and `w_await` (the version in Debian 6 does not have these fields, I believe, though I have not confirmed). This change refactors a bit for testing, adds tests, and corrects the header-parsing regular expression to allow underscores.
