[Tagging] Feature Proposal - RFC - building=carport

[Joachim]

The tag building=carport is used for is used for one carport building.
The carport might provide more than one parking space.

Rationale:
A carport is distinctive enough from building=garage and building=roof
so that an own tag should be used. The plural (like building=garages)
is not defined since all wide carports I could find can be classified
as one structure. The key building=* is used since a carport is a type
of building=roof.

Add amenity=parking/motorcycle_parking/bicycle_parking +
building=carports to mark the parking facility. If there are multiple
carports at a parking site add the tags to an area surrounding them.
These tags are usually not necessary for private parking.
