improvements from work:
- no longer export classes; instead inline functions where it makes
sense (e.g. the scope timers) or export the member functions directly
- fix icc11 warnings
- add some comments
This was SVN commit r6531.
- displaying symbol values requires stack pointer, not frame pointer
- update debug_IsPointerBogus
- skip-n-frames code changed to skip-all-frames-up-to-func (more
reliable in the face of inlining)
debug.cpp: cleanup
This was SVN commit r6410.
