* fhandler_raw.cc (fhandler_dev_raw::open): Eliminate compatibility 

code since no Win32 device names are used anymore.
        * fhandler_tape.cc (fhandler_dev_tape::tape_set_blocksize): Allow
        0 as blocksize to indicate variable blocksize.
        * path.cc (win32_device_name): Generate NT internal device names
        using upper/lower case names for readability.
        Generate \DosDevices\<letter>: device name for mount table
        compatibility devices.
