bitfield struct type status_flags.  Drop unused has_written bit.
	Add accessor methods.
	(fhandler_dev_raw::clear): Remove.
	(fhandler_dev_raw::reset_devbuf): Remove.
	* fhandler_floppy.cc (fhandler_dev_floppy::lseek): Use accessor method
	for is_writing.
	* fhandler_raw.cc: Use status accessor methods throughout.
	(fhandler_dev_raw::clear): Remove.
	(fhandler_dev_raw::fhandler_dev_raw): Drop clear call.
	(fhandler_dev_raw::~fhandler_dev_raw): Ditto.
	* fhandler_tape.cc: Use mtinfo::status accessor methods throughout.
	(mtinfo_drive::close): Fix conditional to enable BSD semantics
	correctly.
	(mtinfo_drive::get_status): Rename from mtinfo_drive::status.
	* mtinfo.h (class mtinfo_drive): Move status bits into private bitfield
	struct type status_flags.  Add accessor methods.
	Rename status method to get_status.
