H.J. Lu d6daff1261 Hide __readv and __writev [BZ #18822]
Hide internal __readv and __writev functions to allow direct access

	(__writev): Likewise.
	* misc/readv.c (__readv): Add libc_hidden_def.
	* misc/writev.c (__writev): Likewise.
	* sysdeps/posix/readv.c (__readv): Likewise.
	* sysdeps/posix/writev.c (__writev): Likewise.
	* sysdeps/unix/sysv/linux/readv.c: Include <sys/uio.h>.
	(__readv): Likewise.
	* sysdeps/unix/sysv/linux/writev.c: Include <sys/uio.h>.
