Intel PT decoding is done in time order. In order to support efficient time interval filtering, add a facility to "fast forward" towards a particular timestamp. That involves finding the right buffer, stepping to that buffer, and then stepping forward PSBs. Because decoding must begin at a PSB, "fast forward" stops at the last PSB that has a timestamp before the target timestamp.
