Adjusted installation dirs and source files - FS driver cp command uses DS_DRIVER_ACTION_DATA message - New libfs.sh to deal with datastore protocol - New xpath.rb to get XML elements in shell programs - Change oned.cong and OpenNebula core files to use DATASTORE instead of IMAGE - Change mkfs driver function to use the drv action data
