Renaming sp_pcontext members and methods; less cryptic and more consistent.

Also added comments, and fixing some coding style (mostly in comments too).
There are no functional changes, so no tests or documentation needed.
(This was originally part of a bugfix, but it was decided to not include this
 in that patch; instead it's done separately.)
