Refactor/mstp zero config state machine (#676)

Browse Source 
* Changed MS/TP master node self destination checks to be located in receive FSM

* Changed MSTP zero configuration: modified comments for state transition names; modified next station increment; refactored the UUID rand() to not be required by common zero config implementation; added more unit tests.

* Added another context to MS/TP user data to allow additional user data
