Lock profiling and lock order verification status, week 7

[Greg Miller]

I checked in a set of test cases for use with "prove", but not all of
my tests cases have been cleaned up and converted yet. The July 4
holiday and related travel slowed work down more than I had
anticipated.

Goals for this week are to finish checking in test cases for the work
completed so far, have libwitness log data about LoRs, and provide the
API functions to retrieve the logged data.
