use of _link in slightly curved intersection

[gheift]

On a slightly curved interchange, the routing preferes motorway_link instead of motorway. The _link is approximatly 10m shorter and has the same max_speed.

Similar, but half of the motorway has no speed_limit.

To fix this, we would need penalties for taking highway exists. I think there is no easy way to reflect this in the profile yet. Might be something for future versions.

see #477 for an issue on using way types to compute turn penalties
