blktrace: load improvements
- Set the state explicitly to SETTING_UP when loading the
traces. This could take a while, so tell the status thread
that we are setting up so it knows how to display us
correctly.
- Fix a bug with multiple devices where we didn't cache the
major/minor properly. This made blktrace spend tons of CPU
cycles looking up /sys.
- Handle multiple devices correctly when adding files.
