- RT Semaphores subsystem removed, the Mutexes implements a better solution
for the same problem.
+- Fixed a bug in the round robin scheduling mode, see the bug tracker for
+ details and a fix for previous versions.
- More performance improvements to the scheduler, see the remarks into the

+ chSchWakeupS() function source. This change makes the ready list insertion
+ time in many cases constant (not influenced by the number of ready threads).
+ The worst case is always proportional to the number of threads in the ready
+ list but the normal case is much more often constant than linear. See the
+ new benchmarks added to the test suite.
- Added mutexes test cases and new benchmarks to the test suite.
- Modified the test suite in order to have each test case to have the same
alignment enforced on functions. This is done to reduce MAM/Cache alignment
