Work in progress: Redesign pt-diskstats in Perl.

Browse Source 
Mostly bits and pieces at the moments. ReadKeyMini is a portable-ish
Term::ReadKey. Used here by DiskstatsMenu, which is currently only
for show.

Diskstats has most of the logic of the old pt-diskstats, with parts
now implemented by the DiskstatsGroupBy* classes; The latter subclass
the former.

As mentioned at the start, this is a work in progress. In addition to to
not having all the parts attached, also missing are the data-gathering mode,
the command-line argument parsing, and a large amount of tests.
