    DEVFS - Factor out recursive code into iterate_topology
    
    * Factor out the recursive code which scans through all nodes in
      the topology into a function, devfs_iterate_topology, which takes
      a callback as argument, which is called for every node.
    
    * Create new callback functions for all functions that were recursive
      before, containing the code that was executed for each node.
    
    * Change all callers of recursive functions to call
      devfs_iterate_topology with the respective callback function
      instead of having their own recursive functions.
