This new design will work even when threads that need to receive
messages from RT threads are created *after* the RT threads. The
existing design would fail because the RT thread(s) would never
be known the later created threads, and so signals emitted by the
RT thread and causing call_slot() in the receiver would end up
being enqueued using a lock-protected list. The new design ensures
that communication always uses a lock-free FIFO instead
Fixes all kinds of miscellaneous issues with MCP. Also removes several theoretical pan modes, replace "Tracks"
pan mode with "Trim", and takes a tiny step towards view modes
in any way that causes problems, just loss of pre-existing connectivity.
1. retain state of current device (and serialize to disk) when switching
devices, and restore that state when switching back to it.
2. fix port and surfacenaming.
3. fix bundle assembly so that all ports (for multi-surface combos) work.
4. rationalize master position numbering
5. add small sleep before starting device handshake after reconnection. This
is ugly but seems to be necessary, unfortunately.
This was necessary due to a bug/design issue between Glibmm and Glib (see https://bugzilla.gnome.org/show_bug.cgi?id=561885)
but the problem needs to be managed by the *creator* of the IOSource and that has now moved inside CrossThreadChannel.
* 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;

* delays Mackie's led initialization until the Mackie is actually ready to receive messages;
* at the button X function mapping customization interface in Preferences:
o show specific device names instead of global ones;
o mark the buttons that are actually available in the device with a *;
o included a bottom text explaining what the * means;
* created a DeviceInfo::get_global_button_name(Button::ID) method;
* included several DEBUG_TRACE in mackies code;
* renamed device buttons and groups according to the following logic: Mackie buttons are named exactly like a actual (mine) Mackie names them on the interface itself. Logic Control buttons are named exactly like they appear at Logic Pro 7.2.1 Dedicated Control Surface Support manual;
* improved timecode display (new format);

* implements Metering on/off through Button::Read as per Seablade's suggestion. I choose this button as it's the "Show meters" button in Traktion;
* removes redundant code from Meter::update_transport_rolling();
* renames Meter::update_transport_rolling() to Meter::notify_metering_state_changed();
* renamed Surface::notify_transport_state_changed() to Surface::notify_metering_state_changed();
* renamed Strip::notify_transport_state_changed() to Strip::notify_metering_state_changed();
* created MackieControlProtocol::notify_metering_state_changed() and made MackieControlProtocol::notify_transport_state_changed() use it;
* implemented turning off of timecode display and two char display in Surface::zero_all ();
* implemented master fader zeroing in Surface::zero_all ();
* calling Surfaces->zero_all() at MackieControlProtocol destructor;
* implemented restore of 2nd LCD line content after metering being active.
