Volker Ruppert cb8faeee52 - implemented new mechanism to update device config parameters that depend on
each other. Devices can register a handler to update it's state after runtime
  configuration. The new method update_runtime_options() executes all registered
  device handlers before the simulation continues.
- USB host controllers now using the new mechanism to handle the runtime device
  change (replaces the previous timer-based implementation). TODO: floppy and
  cdrom could use this feature, too)
- improved USB device change messages
