Update.

	* include/unistd.h: Declare __libc_open64, __libc_lseek64,
	__libc_pread, __libc_pread64, __libc_pwrite, and __libc_pwrite64.
	* io/Versions: Export __libc_open64 and __libc_lseek64.
	* posix/Versions: Export __libc_pread, __libc_pread64, __libc_pwrite,
	and __libc_pwrite64.
	* sysdeps/generic/open64.c: Define __libc_* variant for cancelation
	wrapper.
