Remove all uses of alloca() from this module. The alloca() return value isn't checked, and it *is* possible that a very large alloca() call is made, e.g. when a large registry value is being read. I don't know if alloca() in that case returns NULL or returns a pointer pointing outside the stack, and I don't want to know -- I've simply replaced all calls to alloca() with either PyMem_Malloc() or PyString_FromStringAndSize(NULL,) as appropriate, followed by a size check. This addresses SF buf 851056.
