* ne2000/ne2000.c: Add --ne2k-irq and --ne2k-port boot command
        line configure options.

        * ide/ide.c: Fix a bug which left 4 words in the buffer of the
        disk. Some devices do not follow the standard and terminate the
        command which a new command occurs and/or low data ready when data
        is still to be read.
