A variety of further cleanups to ttyinfo():

- Rename temporary variable names ("tmp", "tmp2") to more informative
  names ("load", "pctcpu", "rss", ...)

- Unclutter indentation and return paths: rather than lots of nested
  ifs, simply return earlier if it's not going to work out.  Simplify
  general structure and avoid "deep" code.

- Comment on the thread/process selection and locking.

- Correct handling of "running"/"runnable" states, avoid "unknown"
  that people were seeing for running processes.  This was due to
  a misunderstanding of the more complex state machine / inhibitors
  behavior of KSE.

- Do perform ttyinfo() printing on KSE (P_SA) processes, it seems
  generally to work.

While I initially attempted to formulate this as two commits (one
layout, the other content), I concluded that the layout changes were
really structural changes.
