* mach/devstream.c (devstream_write, devstream_read): New functions.

USE_IN_LIBIO] (cookie_io_functions_t): Define as macro for __io_functions. (funcsio): Use cookie_io_functions_t type name. (fopenport): Renamed from __fopenport.

(fopencookie): Use it. * libio/libio.h: Declare _IO_cookie_init. * hurd/vpprintf.c (vpprintf) [USE_IN_LIBIO]: Implement using _IO_cookie_init. * libio/libio.h (__io_seek_fn): Fix second argument type to be a pointer, in line with the manual and the old stdio. * libio/iofopncook.c (_IO_cookie_seek): Fix (sole) caller. * sysdeps/generic/bits/stdio-lock.h: New file.
