fixes for desirable playback when using seamless looping.

Try to make sure that we appropriately reset and refill track
buffers whenever we enter/leave loop playback,and whenever
we locate. In addition, if we start playing somewhere other
than the loop range while loop is enabled, then the first
time we hit the loop end, set up the track buffers.
