Paul Davis 71427323ec MCP: latest patch from Rodrigo: 
* fixes Master Fader Touch button in the Mackie;
    * implements a MasterFaderTouch global button;
    * removes unused MackieControlProtocol::_transport_previously_rolling property;
    * implements DeviceInfo::get_global_button() method;
    * creates GlobalButtonsInfo and StripButtonsInfo types in DeviceInfo;
    * implements Surface::_last_master_gain_written property to help master fader feedback;
    * makes Surface respect _mcp.device_info().strip_cnt() to create master fader and when connecting signals for strips and master fader instead of using hardcoded 8;
    * removed a few unnecessary updates in Surface::turn_it_on();
    * included master_gain_changed() in Surface::periodic();
    * implemented MackieControlProtocol::master_fader_touch_press and
    * MackieControlProtocol::master_fader_touch_release;
