	score/src/threaddispatch.c, score/src/threadinitialize.c: Add
	SuperCore handler Timestamp to provide an opaque class for the
	representation and manipulation of uptime, time of day, and the
	difference between two timestamps. By using SuperCore Timestamp, it
	is clear which methods and APIs really have to be struct timespec and
	which can be in an optimized native format.

	score/src/coretodgetuptimetimespec.c: New files.
