IVGCVSW-3905 Create a first implementation of the send thread

 * Added the send thread directly to the SendCounterPacket class
 * Updated the SendCounterPacket class constructor to also take a
   reference of a IProfilingConnection object, used to send packets out
 * Added Start and Stop methods to SendCounterPacket to start and
   stop the send thread
 * Added mutex and wait condition to make the send thread waiting for
   something to send
 * This implementation used the old IBufferWrapper interface
 * Added defult (empty) constructor for the Packet class
 * Refactoring of IPeriodicCounterCapture and SocketProfilingConnection
 * Modified WritePacket to make it match IBufferWrapper::GetReadBuffer
 * Added unit test for regular and stress testing of the send thread
