First step of data flow refactoring.

This moves all data source connections into the TrackDataHub. There are still many things to (re)do here: - Optimizations about when the listeners are registered - Optimizations about what data each TrackDataListener is interested in - When activities are restarting, send new data since they were stopped (instead of doing a full reload) - Proper double-buffering of Location objects (some listeners are interested in double-buffering all points, while others are only interested in double-buffering sampled points) - etc.

+ * This class handles MyTracks related broadcast messages.
+ *
+ * One example of a broadcast message that this class is interested in,
+ * is notification about the phone boot.  We may want to resume a previously
+ * started tracking session if the phone crashed (hopefully not), or the user
+ * decided to swap the battery or some external event occurred which forced
+ * a phone reboot.
+ *
+ * This class simply delegates to {@link TrackRecordingService} to make a
+ * decision whether to continue with the previous track (if any), or just
+ * abandon it.
