Renamed softpipe directories and files to something less confusing.

softpipe/state_tracker --> state_tracker/
softpipe/              --> pipe/
softpipe/generic       --> pipe/softpipe/

I don't think pipe is a great name, but I disliked all the others too.
Luckily it's fairly easy to rename with git, so this can be revisited
later.
