(xalloc_fail): Renamed from fixup_null_alloc.

(xcalloc): #ifdef-out unused function.
(xrealloc): Remove code to work around deficient versions of realloc.
Now we have an autoconf-enabled replacement version.
(xmalloc): Remove code to work around deficient versions of malloc.
Now we have an autoconf-enabled replacement version.
