Remove __need macros from stdio.h and wchar.h.
wint_t is a little finicky because it might be defined by stddef.h, which belongs to the compiler. In addition to the _types_, a bunch of other declarations shared between wctype.h and wchar.h are factored out to their own header. * libio/bits/types/FILE.h, libio/bits/types/__FILE.h * wcsmbs/bits/types/mbstate_t.h, wcsmbs/bits/types/__mbstate_t.h * wcsmbs/bits/types/wint_t.h: New single-type definition files. * wctype/bits/wctype-wchar.h: New file holding declarations shared between wctype.h and wchar.h. * libio/Makefile, wcsmbs/Makefile, wctype/Makefile: Install them. * include/bits/types/FILE.h, include/bits/types/__FILE.h * include/bits/types/mbstate_t.h, include/bits/types/__mbstate_t.h * include/bits/types/wint_t.h, include/bits/wcsmbs-wchar.h: New wrappers. * include/stdio.h, include/wchar.h, include/wctype.h: No need to handle __need macros. * grp/grp.h, gshadow/gshadow.h, hurd/hurd.h, iconv/gconv.h * libio/stdio.h, mach/mach.h, misc/mntent.h, pwd/pwd.h * shadow/shadow.h, stdio-common/printf.h, wcsmbs/uchar.h * wcsmbs/wchar.h, wctype/wctype.h * sysdeps/generic/_G_config.h, sysdeps/unix/sysv/linux/_G_config.h Use the new files instead of __need macros.
