  malloc-h: Fix compilation errors in C++ mode on Android.
  
  * lib/malloc.in.h: Don't include <stdlib.h>, except on Solaris and on
  HP-UX. Include <stddef.h>. Make _GL_ATTRIBUTE_DEALLOC_FREE work (code
  snippet copied from string.in.h and wchar.in.h).
  * m4/malloc_h.m4 (gl_MALLOC_H_REQUIRE_DEFAULTS): Invoke
  gl_STDLIB_H_REQUIRE_DEFAULTS.
  * modules/malloc-h (Depends-on): Add stddef, stdlib.
  (Makefile.am): Substitute GNULIB_FREE_POSIX and REPLACE_FREE.
