 * Convert own macros to OST macros when OST tracing is used.

 * In OST tracing, aTraceName must be a unique identifier in scope of a module. 

 * Thus many OST compiling errors may occur if the same TraceName is used in multiple

 * tracing lines where tracing is miigrated from non-OST to OST. 

 * The fix is to renaming the TraceName:s to be unique.
