devbufalign. (class fhandler_dev_floppy): Remove member bytes_per_sector; * fhandler_floppy.cc (bytes_per_sector): Define as devbufalign. (fhandler_dev_floppy::open): Set devbufalign to a multiple of the sector size and handle devbuf allocation and alignment in !O_DIRECT case here. Change comment accordingly. Call FSCTL_ALLOW_EXTENDED_DASD_IO for partitions as well. (fhandler_dev_floppy::raw_write): Fix comment. Rewrite and fix writing behaviour when application uses read and lseek. (fhandler_dev_floppy::lseek): Use rounddown macro. Call SetFilePointerEx rather than the old SetFilePointer. (fhandler_dev_floppy::ioctl): Reformat switch. Call IOCTL_DISK_UPDATE_PROPERTIES rather than IOCTL_DISK_UPDATE_DRIVE_SIZE in BLKRRPART case. Support BLKIOMIN, BLKIOOPT, BLKPBSZGET and BLKALIGNOFF. * fhandler_raw.cc (fhandler_dev_raw::fhandler_dev_raw): Initialize all devbuf-related members. (fhandler_dev_raw::~fhandler_dev_raw): Delete devbufalloc rather than devbuf. (fhandler_dev_raw::open): Drop allocating devbuf. (fhandler_dev_raw::dup): Allocate devbufalloc and set devbuf to support new sector-aligned devbuf handling. (fhandler_dev_raw::fixup_after_exec): Ditto. * fhandler_tape.cc (fhandler_dev_tape::open): Ditto, set devbufalign to 1. * include/cygwin/fs.h (BLKIOMIN): Define. (BLKIOOPT): Define.
