IVGCVSW-3902 Create IReadOnlyPacketBuffer, IPacketBuffer and IBufferManager interfaces

 * Create IReadOnlyPacketBuffer, IPacketBuffer and IBufferManager interfaces
 * Add Read and Write util functions that use IPacketBuffer
 * Add MockBufferManager using IBufferManager for testing
 * Modify SendCounterPacket to use IBufferManager
 * Modify MockStreamCounterBuffer to use IBufferManager
 * Remove IBufferWrapper and MockBuffer
 * Add MockPacketBuffer for testing
 * Modify unit tests to use the new interfaces
