* Instead of using local capabilities within core's context area implementation for stack allocation/attachment, simply do both operations while stack gets attached, thereby getting rid of the local capabilities in generic code * In base-hw the UTCB of core's main thread gets mapped directly instead of constructing a dataspace component out of it and hand over its local capability * Remove local capability implementation from all platforms except Linux Ref #1443
