Replace RTEMS objects with custom implementation

Browse Source 
Performance analysis revealed that the standard RTEMS objects are a
major bottleneck.  The object get mechanism and attribute checks at
runtime have a significant overhead.  Use a custom implementation for
synchronization primitives.  This drops also the size of the
synchronization primitives considerably.
