runtime/
* time.c: Time-estimation with minimal dependency on xtime.
runtime/transport/
* transport/transport.c (_stp_handle_start): Initialize timer functions.
* transport.c (_stp_cleanup_and_exit): Teardown timer functions.
tapset/
* timestamp.stp (gettimeofday_us, gettimeofday_ms, gettimeofday_s):
Convert to using the runtime-provided _stp_gettimeofday_us().
