Subject: * libio/libio.h (_IO_FILE): Revert type of _chain to _IO_FILE*.

* libio/libioP.h (_IO_ITER): Revert to type _IO_FILE*.
(FILEBUF_LITERAL): Add cast for CHAIN init.

(_IO_flush_all, _IO_flush_all_linebuffered, _IO_unbuffer_write):
Revert type of `fp' to _IO_FILE*.
(_IO_iter_file): Remove cast.
(_IO_iter_next): Elide intermediate member reference.
