server.c (load_data, run_shell): Use xmalloc, xrealloc & xcalloc in lieu of malloc, realloc & calloc.

	* fixinc/server.c (load_data, run_shell): Use xmalloc, xrealloc &
	xcalloc in lieu of malloc, realloc & calloc.

	* gencheck.c (xmalloc): Use really_call_malloc, not malloc.

	* gengenrtl.c (xmalloc): Likewise.

	* gensupport.c (xcalloc, xrealloc, xmalloc): Use the
	really_call_* memory allocation routines.

	* stmt.c (check_for_full_enumeration_handling): Use
	really_call_calloc, not calloc.

	* system.h (really_call_malloc, really_call_calloc,
	really_call_realloc): Define.
	(malloc, realloc, calloc, strdup, bzero, bcmp, rindex): Poison.

f:
	* fini.c (main): Use really_call_malloc, not malloc.
