Headers 3 headers related to message registers and utcbs are now merged under utcb.h in libl4. Some message register definitions used by the kernel are now moved into kernel's glue/message.h. This avoids the duplication of same definitions. Also the total number of mregs are now determined by arch-specific kernel header, which is good.
