Stack management for PIPS contexts.

A PIPS context contains a pointer in the PIPS debug level stack. When a PIPS context is popped, the debug level stack is restored. It may be the current level!

Example: voir catch_user_error() in library pipmake, or a PIPS user interface such as wpips, tpips or pips
