This is the final portion of the large series for adding MST
suspend/resume reprobing that I've been working on for quite a while

* Refactored and cleaned up any code I ended up digging through in the
process of understanding how some parts of these helpers worked.
* Added some debugging tools along the way that I ended up needing to
figure out some issues in my own
