    Also fix a left over reference to HAL in default.pa

    volume: Add a PA_VOLUME_UI_MAX define for the recommended max volume to show in UIs
    
    This value is not a technical upper limit, it's just a 'sensible'
    value that is not crazy high, but also allows software amplification
    above 0dB (aka 100%) for very quiet audio sources.
    
    We recommend that a comprehensive volume control UI should allow
    users to set volumes up to this limit, although of course should
    deal gracefully if the user has set the volume even higher than this
    without resulting in a feedback loop that effectively limits the
    upper volume.
    
    The value chosen is +11dB. This was selected somewhat subjectively
    and is very similar to the current 150% that gnome-volume-control
    uses (which is ~+10.57dB).
    
    On the plus side, we now recommend that everyone allows
    'Volumes up to 11' which is pretty awesome.
