Update.

	* include/sys/socket.h: Declare __libc_sa_len_internal and define
	SA_LEN macro to use it if not NOT_IN_libc.
	* sysdeps/unix/sysv/linux/sa_len.c: Use INTDEF for __libc_sa_len.

	* include/fcntl.h: Declare __open_internal and define __open and
	__libc_open macros if not NOT_IN_libc.
	* sysdeps/generic/open.c: Use INTDEF for __open.
	* sysdeps/mach/hurd/open.c: Likewise.
	* sysdeps/unix/sysv/aix/open.c: Likewise.
	* sysdeps/unix/syscalls.list: Add __open_internal alias.

	* sysdeps/generic/check_fds.c: Make sure newly opened file descriptor
	has correct number.

	* include/fcntl.h: Define __libc_fcntl macro if not NOT_IN_libc.
	* sysdeps/mach/hurd/fcntl.c: Undefine __libc_fcntl as well.
	* sysdeps/unix/sysv/aix/fcntl.c: Likewise.
	* sysdeps/unix/sysv/linux/i386/fcntl.c: Likewise.

	* include/wctype.h: Declare __iswalpha_l_internal,
	__iswdigit_l_internal, __iswspace_l_internal,
	__iswxdigit_l_internal, and __iswctype_internal.  Define
	__iswalpha_l, __iswctype, __iswdigit_l, __iswspace_l, and
	__iswxdigit_l macros if not NOT_IN_libc.
	* wctype/iswctype.c: Use INTDEF for __iswctype.
	* wctype/wcfuncs_l.c: Use INTDEF for all __iswXXX_l.
