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.
