    qemu-iotests: qemu machine type support
    
    This patch adds qemu machine type support to the io test suite.
    Based on the qemu default machine type and alias of the default machine
    type the reference output file can now vary from the default to a
    machine specific output file if necessary. When using a machine specific
    reference file if the default machine has an alias then use the alias as 
the output
    file name otherwise use the default machine name as the output file name.
