xalloc-oversized: check for PTRDIFF_MAX too This avoids undefined behavior when subtracting pointers to objects containing more than PTRDIFF_MAX bytes. * lib/xalloc-oversized.h (__xalloc_oversized, xalloc_oversized): Also return 1 if the result would exceed PTRDIFF_MAX> * modules/xalloc-oversized (Depends-on): Add stdint.
