Lock profiling and lock order verification status report #6

[Greg Miller]

Accomplishments for the week:

* LoRs are now detected by libwitness (but data about LoRs is not yet logged)

My goal for the next week is to begin cleaning up and committing test
cases and make libwitness store data about LoRs.

Other tasks that remain to be done:

* Generate reasonable lock names in libwitness
* Implement witness support functions (e.g., to allow the user to
ignore ordering between two locks, specify an order for a pair of
locks, retrieve LoR info, etc)
* Generate XML output files for both lock profiling and libwitness
* Commenting and style fixes
* Further testing
