* renamed malloc.h mymalloc.h, and added MALLARG as the type of the
argument to malloc() (size_t or unsigned int)
* listobject.c: check for overflow of the size of the object,
so things like range(0x7fffffff) will raise MemoryError instead
of calling malloc() with -4 (and then crashing -- malloc's fault)
