* libcsupport/src/__times.c, libmisc/cpuuse/cpuusagereport.c, libmisc/cpuuse/cpuusagereset.c, libmisc/monitor/mon-task.c, rtems/include/rtems/rtems/ratemon.h, rtems/src/ratemongetstatus.c, rtems/src/ratemonperiod.c, score/include/rtems/score/thread.h, score/src/threaddispatch.c, score/src/threadinitialize.c, score/src/threadtickletimeslice.c: Add typedefs for cpu usage and period timing statistics. Also renamed related variables and structure members so they are the same whether you are using nanosecond (e.g. struct timespec) or ticks (e.g. uint32_t) granularity. This lays the groundwork for future cleanup.
