Allow tracing code outside of trace.c to access tracing_set_clock(). Some applications may require a particular clock in order to function properly, such as latency calculations. Also, add an accessor returning the current clock string.
It seems this patch should be merged in the next patch, which is actual consumer of this API. Thank you,
