  realloc-posix: realloc (..., 0) now returns nonnull
  
  * lib/realloc.c (rpl_realloc): Simplify and tune by using
  HAVE_REALLOC_0_NONNULL and HAVE_MALLOC_PTRDIFF, and
  by having just one call to realloc instead of two.
  * lib/reallocarray.c (reallocarray): Simplify and tune
  by delegating the zero case to the revised realloc.
  * m4/eealloc.m4 (_AC_FUNC_REALLOC_IF): Since only eealloc uses
  this macro now, move its definition here ...
  * m4/realloc.m4: ... from here.
  (gl_FUNC_REALLOC_0_NONNULL): Also check that realloc (p, 0)
  returns nonnull.  Require gl_FUNC_REALLOC_POSIX.
  Define HAVE_REALLOC_0_NONNULL.
  * m4/reallocarray.m4 (gl_FUNC_REALLOCARRAY):
  Also replace reallocarray if it returns a null pointer for size zero.
  * modules/eealloc (Files): Remove m4/realloc.m4.
  * modules/realloc-posix (Depends-on): Add extensions-aix.
  * modules/reallocarray (Files): Add m4/realloc.m4.
