Use new QEMU test project to improve stream/message buffer tests (#168)

Browse source 
* Add Eclipse/GCC project that targets the LM3S8962 QEMU model.

* Get the Cortex-M QEMU project working.

* Continue working on making stream buffer demo more robust and QEMU project.

* Rename directory CORTEX_LM3S8986_QEMU to CORTEX_LM3S6965_QEMU.
Work on making the Stream Buffer tests more robust.
Check in before adding in the trace recorder.

* Rename CORTEX_LM3S6969_QEMU to CORTEX_LM3S6969_GCC_QEMU.

* Make the StreamBufferDemo.c common demo file (test file) more robust to other test tasks running at an equally high priority.

* Work in progress checkin only - comments in main.c are incorrect.

* Correct comments at the top of FreeRTOS/Demo/CORTEX_LM3S6965_GCC_QEMU/main.c
Make the message buffer tests more robust in the case the a message buffer becomes full when prvSenderTask() has a higher priority than the reader task.

* Disable trace recorder in the LM3S6965 QEMU demo.

* I'm dropping FreeRTOS-Kernel reference update, since this seems to break the CMBC CI.
