IVGCVSW-3951 Create the timeline decoder

 * Added ITimelineDecoder.h C interface
 * Added an example implementation of ITimelineDecoder.h
 * Added command handlers for the timeline directory and objects
 * Added tests for the decoder implementation
 * Changed ReadSwTraceMessage to take a const unsigned char*
   so it can be used by the directory command handler
 * Fixed some bugs in ProfilingUtils.cpp and related tests
