Repacker stats

Hi

This patch allows reading of repacker stats while it is working. It creates two files in repacker sysfs hierarchy: formatted_nodes and unformatted_nodes, which correspond to the stats that repacker prints after it has finished.

The patch seems pretty safe, though I wait for confirmation from zam on that ;-).

Cheers for the sikkhmeister :)

I started hacking something of an analyzer, but being in this very tired mood and all, I think at least the math parts of it are broken ;)

Kludgy to the max, but I hope I can teach it to do graphs at some point and also to start and stop the repacker with different settings. Once that's done, all it needs is a port to C and it should be shippable.

All help is appreciated, as always.
