	* libio/ioseekoff.c: Remove INTDEF.  Define _IO_seekoff_unlocked.  Same
	as old code without locking.  _IO_seekoff calls this function after
	locking the stream.
	* libio/ioseekpos.c: Likewise for _IO_seekpos.
	* libio/libioP.h: Replace _IO_seekoff_internal and _IO_seekpos_internal
	prototypes with _IO_seekoff_unlocked and _IO_seekpos_unlocked
	prototypes.
	* libio/iolibio.h (_IO_fseek): Call _IO_seekoff_unlocked instead
	of _IO_seekoff_internal.
	(_IO_rewind): Likewise.
	* libio/ioftell.c: Likewise.
	* libio/ftello.c: Likewise.

	* libio/iofsetpos64.c: Likewise.
	* libio/oldiofsetpos.c: Likewise.
	* libio/oldiofsetpos64.c: Likewise.

	* libio/wfileops.c (_IO_wfile_seekoff): Don't modify _offset and
	_wide_data->_IO_read_end if adjustment can be made in the current
	buffer.
