* libio/genops.c (_IO_unbuffer_write): Don't always free the

	buffer.  This is not necessary except in debug mode.  If we don't
	free the buffer but the FILE structure to a list.
	(buffer_free): New function.  Free buffers or tell _IO_unbuffer_write
	to do so.
	* libio/libio.h (struct _IO_FILE): Add new members to keep track
	of which buffers have to be freed.
