This feature removes the dependency on malloc/free for constrained
embedded systems without a heap. It uses a static heap inside
Unity Fixture. Setting UNITY_INTERNAL_HEAP_SIZE_BYTES sizes the heap.
Add tests for new option, add targets to makefile for running tests.
UNITY_FIXTURE_MALLOC for Fixture use only, remove from unity_output_Spy.c.
- fixed a few bugs in fixtures to get it to pass against our standard compilers
- added extern of OUTPUT_CHAR method to keep compilers from complaining
