* Makefile.in (c-exp.tab.c, m2-exp.tab.c): Add sed patterns to

remap all malloc's to xmalloc's and all realloc's to xrealloc's.
	* c-exp.y, m2-exp.y:  Add comment about how malloc/realloc are
	  remapped to xmalloc/xrealloc, use only malloc/realloc in grammer
	  file.  Remove preprocessor defines that previously did remapping.
