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.
