stdlib: let modules use system malloc, realloc
* lib/stdlib.in.h (malloc, realloc): Don't #define or add warnings
if !_GL_USE_STDLIB_ALLOC.
+ (malloc, realloc): Limit this change to a smaller scope.
+
* lib/careadlinkat.c (_GL_USE_STDLIB_ALLOC): Define.
(malloc, realloc): Don't #undef; no longer needed.
* lib/malloca.c (_GL_USE_STDLIB_ALLOC, malloc): Likewise.
rely on GNU or POSIX semantics for malloc and realloc (for example,
by never specifying a zero size), so it does not need malloc or
realloc to be redefined. */
