New description:

 The <rtems.h> header file still exposes a lot of implementation details
 via the definition of internal data structures, e.g. the *_Control
 structures of the API objects. They are only necessary for the application
 configuration. Move them to separate header files. Currently we have:

 * <rtems/rtems/XYZ.h>
 * <rtems/rtems/XYZimpl.h>

 Use

 * <rtems/rtems/XYZdata.h>

 for this new header file.

 Potential new header files are:

 * rtems/rtems/asrdata.h
 * rtems/rtems/barrierdata.h
 * rtems/rtems/dpmemdata.h
 * rtems/rtems/eventdata.h
 * rtems/rtems/messagedata.h
 * rtems/rtems/modesdata.h
 * rtems/rtems/optionsdata.h
 * rtems/rtems/partdata.h
 * rtems/rtems/ratemondata.h
 * rtems/rtems/regiondata.h
 * rtems/rtems/semdata.h
 * rtems/rtems/signaldata.h
 * rtems/rtems/tasksdata.h
 * rtems/rtems/timerdata.h
