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

Use chacheable RAM in IAR project for MPU_M7_NUCLEO_H743ZI2 project (#193)
This change updates the IAR project for Nucleo H743ZI2 to use the
cacheable DTC RAM and enables L1 cache. In order to ensure the correct
functioning of cache, the project sets configTEX_S_C_B_SRAM in
FreeRTOSConfig.h to not mark the RAM as shareable.

Feature/multiple direct to task notifications (#73)
* Add TaskNotifyArray.c with the single task tests updated to use the task notification array up to the point where the timer is created.
* Continue working on TaskNotifyArray.c to test the new task notification indexes. Next TaskNotifyArray.c will be refactored to break the tests up a bit.
* Refactor and update the comments in TaskNotifyArray.c - no functional changes.
* Change from the task notify "array" to task notification "indexed" nomenclature in the new task notification API functions that work on one particular task notification with the array of task notifications.
* Update the implementation of the taskNOTIFY_TAKE() and taskNOTIFY_WAIT() trace macros to take the array index of the task notification they are acting on.
Rename configNUMBER_OF_TASK_NOTIFICATIONS to configTASK_NOTIFICATION_ARRAY_ENTRIES.
Add FreeRTOS/Demo/Common/Minimal/TaskNotifyArray.c to the Visual Studio project - the file implements tests specific to the behaviour of the indexed task notification functions and should be used in addition to the tests already provided in FreeRTOS/Demo/Common/Minimal/TaskNotify.c.

ATmega328PB Xplained Mini -- demo project for ATmega port. (#70)
* Bootstrap a demo from START. No driver is added in this commit.
* Add FreeRTOS source code to project. Remove unnecessary folder nesting.
Heap_4 is used here.
* Copy over main.c, FreeRTOSConfig.h, and regtest.{c, h}.
This commit compiles, but will need some work on timer used.
* This port has 2KB RAM. We are using 1KB for heap.
Further decreasing minimum stack size, and also use stack overflow check 1 to save some stack space.
* Preserve EEPROM set to false.
* End of the line.
* Reduce register test stack size.
32 8-bit register + 10 bytes for stack frame cost. Round up to 50.
* Adding Queue test in Integer test.
- g3 to easy debugging.
- mainCHECK_PERIOD is set to 1000 ticks. Note that this port for now use WDT as tick timer, and period is set to 15ms.
- vErrorChecks, is of highest priority. So if this task gets run before other tasks, the very first check will fail.
* Avoid false alarm.
Since we don't know in which order the tasks are scheduled, clearing any error for the first entry of vErrorChecks.

Change cbmc-viewer invocation in CBMC makefile (#63)
* Exclude FreeRTOS/Demo from CBMC proof reports.
The script cbmc-viewer generates the CBMC proof reports. The script
searches source files for symbol definitions and annotates source
files with coverage information. This patch causes cbmc-viewer to
ignore the directory FreeRTOS/Demo containing 348M of data. The
script now terminates in a few seconds.
* Make report default target for CBMC Makefile.
Modify the Makefile for CBMC proofs to generate the report by default
(and not just property checking) and modify property checking to
ignore failures (due to property assertions failing) and terminating
report generation.

Demo/Posix_GCC: add demo application for Posix port using GCC
This is largely a copy of the Windows demo application with a few key
changes:
- heap_3 (use malloc()/free()) so tools like valgrind "just work".
- printf() wrapped in a mutex to prevent deadlocks on the internal
pthread mutexes inside printf().
SCons (https://scons.org/) is used as the build system.
This will be built as a 64-bit application, but note that the memory
allocation trace points only record the lower 32-bits of the address.

See the conversation https://github.com/FreeRTOS/FreeRTOS/commit/42c627b2b88cb3b487fea983d8b566a8bbae54fa#comments .
Linkage for both ```./FreeRTOS/Source``` and ```./FreeRTOS/Demo``` are removed, since it looks weird to only provide linkage to Demo.

Submodule kernel directory. (#16)
* Removing FreeRTOS/Source in readiness for submoduling.
* Submoduling kernel.
* README.md update due to submoduling.
When releasing, please follow these steps:
1. in local directory, clean directory and check "git status" shows "nothing to commit, working tree clean" for ALL subdirectories.
2. copy source code and instructions only to an empty folder. Git related should not be in this folder -- this covers .git, .gitignore, .github, .gitmodules, gitmessages, ......
3. zip the folder from step 2. (create both .zip and .7z)
4. attach .zip and .7z to the release. (e.g. attach these two in new release -- https://github.com/FreeRTOS/FreeRTOS/releases/new)
5. PLEASE download both, unzip, diff with your local git repo. (should not see any difference other than git related.) And, sanity check a couple of projects.
