Provide additional navigation information via Navigator

With this patch, Navigator becomes able to expose additional running
navigation information such as distance to next maneuver, traveled
distance, and so on.
This information must be made available by the
engines by emitting the related signals and implement the related
methods, in QAbstractNavigator subclasses.

This patch also groups all navigation read-only progress information
into a property group inside Navigator, called directions.
