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.
