       Add reallocarray implementation
       
       reallocarray is nonstandard and glibc declares it only when _GNU_SOURCE
       is defined. Without this patch or _GNU_SOURCE (for glibc < 2.29) defined,
       you get a segfault from reallocarray being implicitly declared with the
       wrong signature.
