[BZ #9759]

	* dirent/dirent.h: Adjust prototypes of scandir, scandir64, alphasort,
	alphasort64, versionsort, and versionsort64 to POSIX 2008.
	* dirent/alphasort.c: Adjust implementation to type change.
	* dirent/alphasort64.c: Likewise.
	* dirent/scandir.c: Likewise.
	* dirent/versionsort.c: Likewise.
	* dirent/versionsort64.c: Likewise.
	* sysdeps/wordsize-64/alphasort.c: Add hack to hide alphasort64
	declaration.
	* sysdeps/wordsize-64/versionsort.c: Add hack to hide versionsort64
	declaration.
