* fhandler.h (class fhandler_dev_raw): Delete current_position and

	eof_detected status flag.  Delete is_eom and is_eof methods.
	Move drive_size, bytes_per_sector, eom_detected status flag, as well
	as the methods read_file, write_file, raw_read and raw_write to ...
	(class fhandler_dev_floppy): ... here. Remove is_eom and is_eof
	methods.  Add dup method.
	* fhandler_floppy.cc (IS_EOM): New macro.
	(fhandler_dev_floppy::is_eom): Remove.
	(fhandler_dev_floppy::is_eof): Remove.
	(fhandler_dev_floppy::fhandler_dev_floppy): Initialize status flags.
	(fhandler_dev_floppy::get_drive_info): Only call EX functions on
	systems supporting them and stop suffering strange delays.
	(fhandler_dev_floppy::read_file): Move here, drop setting
	current_position.
	(fhandler_dev_floppy::write_file): Move here, drop setting
	current_position.
	(fhandler_dev_floppy::open): Rearrange comment.
	(fhandler_dev_floppy::dup): New method.
	(fhandler_dev_floppy::get_current_position): New inline method.  Use
	instead of former current_position were appropriate.
	(fhandler_dev_floppy::raw_read): Move here.  Drop EOF handling.
	(fhandler_dev_floppy::raw_write): Move here.  Drop EOF handling.
	(fhandler_dev_floppy::lseek): Remove useless conditions.  Convert
	sector_aligned_offset to LARGE_INTEGER to improve SetFilePointer call.
	(fhandler_dev_floppy::ioctl): Move blocksize check in RDSETBLK case
	to here.
	* fhandler_raw.cc (fhandler_dev_raw::is_eom): Remove.
	(fhandler_dev_raw::is_eof): Remove.
	(fhandler_dev_raw::write_file): Remove.
	(fhandler_dev_raw::read_file): Remove.
	(fhandler_dev_raw::raw_read): Remove.
	(fhandler_dev_raw::raw_write): Remove.
	(fhandler_dev_raw::dup): Drop copying removed members.
	(fhandler_dev_raw::ioctl): Drop blocksize testing.
	* wincap.h: Implement has_disk_ex_ioctls throughout.
	* wincap.cc: Ditto.
	(wincap_vista): Preliminary wincaps for Windows Vista/Longhorn.
	(wincapc::init): Add Vista/Longhorn handling.
