Major rewrite of native SNMPv3 CommandGenerator and NotificationOriginator

applications towards the following goals:
* avoid bonding with particular SNMP engine instance to promote single
  app instance using many SNMP engine instances
* support two APIs for working with request data: one operates on the
  whole PDU object while the other on PDU contents
* keep callback context data in stack rather than in stateful application
  cache
* newly introduced sendVarBinds() method offers a more functional and
  logical signatures.
* keep backward compatibility for all existing major/documented interfaces

 - Execution Observer facility implemented to give app an inside view
   of SNMP engine inner workings. This is thought to be a generic
   framework for viewing (and modifying) various internal states
