stddef: support C11's max_align_t
* doc/posix-headers/stddef.texi (stddef.h): Document max_align_t.
* lib/stddef.in.h (_@GUARD_PREFIX@_STDDEF_H) [__need_wint_t]:
Do not undef, as that might cause max_align_t to be defined twice.
Instead, change use to check for _GL_STDDEF_WINT_T too.
(max_align_t) [!HAVE_MAX_ALIGN_T]: New decl.
* m4/stddef_h.m4 (gl_STDDEF_H, gl_STDDEF_H_DEFAULTS):
Check for max_align_t.
* modules/stddef (stddef.h): Substitute HAVE_MAX_ALIGN_T.
* modules/stddef-tests (Depends-on): Add stdalign.
* tests/test-stddef.c: Test max_align_t.
