reallocarray: check for ptrdiff_t overflow
* doc/glibc-functions/reallocarray.texi (reallocarray):
Mention ptrdiff_t overflow.
* lib/reallocarray.c (reallocarray): Reindent as per usual GNU.
* lib/stdlib.in.h (reallocarray): Allow reallocarray to be replaced.
* m4/reallocarray.m4 (gl_FUNC_REALLOCARRAY):
Check for ptrdiff_t overflow.
* m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Set up REPLACE_REALLOCARRAY.
* modules/reallocarray (Files): Add malloc.m4.
(configure.ac): Also test REPLACE_REALLOCARRAY.
* modules/reallocarray-tests (Depends-on): Add stdint.
* modules/stdlib (stdlib.h): Substitute REPLACE_REALLOCARRAY.
* tests/test-reallocarray.c: Include stdint.h.
(main): Check for ptrdiff_t overflow.
