Enhance API tracing (#120)

Enhance API tracing to handle more types, and to put tracing info in a string, allowing it to be used when reporting errors.  Also refactor ref-counted strings (H5RS) module to add capabilities needed for the tracing.  Refactored H5Gname.c routines to use new H5RS routines also.  Added /*out*/ tags to API routines that are returning information to the application.  Updated H5TRACE macros from running updated trace script over library code.  Added tests for new H5RS routines.
