unify interface API

  • introduce new interfaces
  • unify location service clients to always expect service ID as the second argument
  • remove obsolete methods that take explicit exchange management arguments (first phase)
  • use interfaces in device drivers, devman, location service, logger, inet
  • Property mode set to 100644
