[mkgmap-dev] barrier & access

Hi Minko,

I can't reproduce that in MapSource with r3160 and default style.  I am always routed to the
next junctions when using bicycle mode. In pedestrian mode I am routed through the barrier.

Well, for the link-pois-to-ways option mkgmap evaluates the access tags beginning with mkgmap: and the 
mkgmap:road-class and mkgmap:road-speed tags (including the min and max versions).
If it finds an access tag, it checks if the POI is more restrictive than the way. If yes, a routing restriction is created.
If it finds a tag like mkgmap:road-class or mkgmap:road-speed, it will use the corresponding values for a part of
the way near the  POI.

OK?
