* fhandler.h (fhandler_dev_raw::write_file): New method, created from former static function. (fhandler_dev_raw::read_file): Ditto. (reset_devbuf): New inline method. (class fhandler_dev_tape): Add TAPE_GET_DRIVE_PARAMETERS member `dp'. (fhandler_dev_tape::write_file): New method. (fhandler_dev_tape::read_file): Ditto. (fhandler_dev_tape::tape_get_feature): Convert to inline method. (fhandler_dev_tape::tape_error): New method, created from former static function. (fhandler_dev_tape::tape_get_blocksize): Remove declaration. * fhandler_raw.cc (fhandler_dev_raw::write_file): New method, created from former static function. (fhandler_dev_raw::read_file): Ditto. (fhandler_dev_raw::writebuf): Accomodate the fact that no devbuf exists under variable block size condition. (fhandler_dev_raw::raw_read): Ditto. Add local p pointer to simplify pointer arithmetic. (fhandler_dev_raw::raw_write): Always set devbufend to 0 when starting with writing. Accomodate the fact that no devbuf exists under variable block size condition. * fhandler_tape.cc: Various formatting changes. (TAPE_FUNC): New macro. Use throughout as tape function loop. (get_ll): Convert into macro. (IS_EOM): New macro. (IS_EOF): New macro. (fhandler_dev_tape::is_eom): Use IS_EOM macro. (fhandler_dev_tape::is_eof): Use IS_EOF macro. (fhandler_dev_tape::write_file): New method. (fhandler_dev_tape::read_file): New method. (fhandler_dev_tape::open): Get drive information block here once. (fhandler_dev_tape::lseek): Remove unneeded duplicate code. (fhandler_dev_tape::dup): Duplicate drive information block. (fhandler_dev_tape::ioctl): Remove drvbuf in variable block size mode. Return ERROR_INVALID_BLOCK_LENGTH instead of ERROR_MORE_DATA if buffer contains data which would get lost on buffer size changing. Use absolute tape positioning also if drive only supports logical block positioning. (fhandler_dev_tape::tape_error): New method, created from former static function. (fhandler_dev_tape::tape_get_pos): Allow logical block reporting. Workaround tape driver bug. (fhandler_dev_tape::_tape_set_pos): Reset device buffer and flags after successful repositioning. (fhandler_dev_tape::tape_set_pos): Allow logical block positioning. Workaround tape driver bug. (fhandler_dev_tape::tape_erase): Use dp instead of calling GetTapeParameters. (fhandler_dev_tape::tape_prepare): Ditto. (fhandler_dev_tape::tape_get_blocksize): Remove. (fhandler_dev_tape::tape_set_blocksize): Don't call tape_get_blocksize. Error handling already done in fhandler_dev_tape::ioctl. (fhandler_dev_tape::tape_status): Remove local `dp' variable. Accomodate logical tape reporting. Call tape_get_feature instead of accessing feature words directly. (fhandler_dev_tape::tape_compression): Use dp instead of calling GetTapeParameters. Fix resetting datcompression.
