IVGCVSW-3691 Implement SendCounterPacket.SendCounterDirectoryPacket() function
* Changed the signature of SendCounterDirectoryPacket to accept any
ICounterDirectory object
* Added helper methods to the SendCounterPacket class for creating the records
* Created mock classes for testing
* Added unit tests for both SendCounterDirectoryPacket and the helper methods
* Added unit tests for the SWTrace utility functions
* Added ReadUint8 utility function for getting single byte out of a buffer
* Disabled extra sign-conversion warning in the conversion macro
