Utcb support has beed added. It has the same drawback as in the stack support: the area in questen has to be already mapped-in. There is some basic infrastructure for utcb to support mapping but it is far from being complete. MAPPING_ENABLE symbolic constant controls this behaviour. There are also some minor fixes for the stack support and the utcb common helper routines.
