NAME    
    hfpGetBestScoPktType
    
DESCRIPTION
    This function looks at the supported features of the remote device and
    returns the most appropriate packet type depending on what packets the other
    end can support. If the remote end supports HV3 then this is the type 
    returned. Failing that it checks if HV2 is supported and if so returns that.
    Otherwise it returns the default packet type that all devices must support
    HV1.
