- Fixup Local* Heap implementation so that calls which have different semantics don't call the Global APIs (ie: LocalAlloc/LocalReAlloc and LocalFlags). The rest can be shared beteween them. Also fix some prototypes.

- Rename all the defintions to BASE_HEAP instead of GLOBAL_HEAP, since they apply just as well to the Local Heap.
