Michael Hohmuth 5aec3c2400 FS#11931 part 2: Allow a short rewind when playback is paused. Patch 
by John Morris.

This patch adds an option to rewind the current track by a few seconds
when it is paused, irrespective of what has caused the pause.  This is
useful for audiobooks and podcasts to allow the listener to recall
where the track was left off.

The patch subsumes the existing rewind-on-headphone-unplug feature and
extends it to all invocations of pause: play/pause button (or touch
area), headphone removal, and power-supply unplug in car-adapter
mode. It also subsumes FS#9448 (rewind on fade).
