	* ChangeLog, configure.ac, libcsupport/src/__times.c,
	libmisc/cpuuse/cpuuse.c, libmisc/stackchk/check.c,
	rtems/include/rtems/rtems/ratemon.h, rtems/src/ratemongetstatus.c,
	rtems/src/ratemonperiod.c, rtems/src/ratemonreportstatistics.c,
	rtems/src/ratemonresetall.c, rtems/src/ratemontimeout.c,
	score/Makefile.am, score/include/rtems/score/thread.h,
	score/include/rtems/score/timespec.h, score/src/threaddispatch.c,
	score/src/threadinitialize.c, score/src/threadtickletimeslice.c,
	score/src/timespecdivide.c: Add nanoseconds granularity to the rate
	monotonic period statistics and CPU usage statistics. This capability
	is enabled by default although may be conditionally disabled by the
	user. It could be too much overhead on small targets but it does not
	appear to be bad in early testing. Its impact on code size has not
	been evaluated either. It is possible that both forms of statistics
	gathering could be disabled with further tweaking of the conditional
	compilation.
	* score/src/timespecdividebyinteger.c: New file.
