I managed to test CC with heap2 changes and the init stack claimed back to heap once scheduler starts.
the changes of this commit are OP related (just cleanup on CC side):
Arch specific stuff (in reset vector) to hide this from portable code:
- switch back to MSP stack before starting the scheduler so that the sheduler can use the IRQ stack (when/if needed).
- call the C portable function in heap2 to claim some stack back (the number to claim is taken from linker file).
- start the scheduler from reset vector (I move this here from main because it make sense to not go back to C (so that I don't need to copy the rolled stack in case the sheduler returns). This make it more clean.
- Also I have added the call to the mem manager if sheduler return. that way, we don't reset indefinitely if memory runs out. We will go to this handler and figure things out (right now, it's just looping but at least not rebooting. Probably trap NMI would be better (later improvement).

Each real time kernel port consists of three files that contain the core kernel components and are common to every port, and one or more files that are specific to a particular microcontroller and/or compiler. + The FreeRTOS/Source/Portable/MemMang directory contains the three sample memory allocators as described on the http://www.FreeRTOS.org WEB site. + The other directories each contain files specific to a particular microcontroller or compiler. For example, if you are interested in the GCC port for the ATMega323 microcontroller then the port specific files are contained in FreeRTOS/Source/Portable/GCC/ATMega323 directory. If this is the only port you are interested in then all the other directories can be ignored.
