Dear all,

I have proposed a new feature - U-turn -  to mark whether U-turning is legally 
allowed on the highway by introducing a new key u_turn = yes / no to be 
applied on highway=* .

This is used for routing purpose, such that when U-turn is allowed, the router 
can instruct the driver to make a U-turn directly on the road, mostly to 
circumvent turn restrictions (for example, turn left then U-turn immediately 
to circumvent no turn right restriction).
