blktrace support now works

One little buglet - the blktrace offset is the sector, not the
byte offset. For now it's hardcoded at 512, should really get
the value from the device.

blktrace support update

This should essentially work, except that it will not delay between
io but just issue the entries as fast as it can. Missing bits:

- Utilize the ipo->delay to suitably delay issuing an io
- Extract device name from blktrace file
