Implement multi threading critical section
From the MT design:
void startPktProcessing(); void stopPktProcessing();
we need too a RAII class implementing stop at the constructor and start at the destructor. I propose
MultiThreadingCriticalSection. The last point to discuss is where to put this, e.g.
The RAII class will be used by DHCPv4 and DHCPv6 server hooks which modify the configuration.
