the macro chSysGetTime() in chTimeNow(), the old names are still recognized
but marked as deprecated (fixes the bug 2678953 but goes a bit further by
introducing a new API category "Time").
+- OPT: Small optimization to the Cortex-M3 port code, improved thread
+ related performance scores and smaller code.
- Removed testcond.c|h and moved the test cases into testmtx.c. Mutexes and
condvars have to be tested together.
- Added architecture diagram to the documentation.
