* 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.
