The new get_bindings IPC interface (IPC_GET_BINDINGS) allows swaymsg (and
other IPC clients) to interrogate sway's input bindings for all configured
binding modes.
The output of get_bindings is a JSON object mapping each configured binding
mode (e.g. "default", "resize", etc.) to an array of binding objects. The
binding JSON objects are of the same form as those in IPC_EVENT_BINDING.
N.B. a big chunk of code from ipc_event_binding() is moved to a new
ipc_json_describe_binding() function which services both the new
IPC_GET_BINDINGS as well as the existing IPC_EVENT_BINDING commands.

Since wayland does not currently allow swaybar to create global
keybinds, this is handled within sway and sent to the bar using a custom
event, so as not to pollute existing events, called bar_state_update.
Detects when a bar modifier key is pressed/released and sends a modifier
IPC event to any listeners (usually swaybars).
This way a swaybar can listen on the modifier event and hide/show the
bar accordingly (not implemented yet)
The modifier event looks like this:
{
"change": "pressed", // or released
"modifier": "Mod4"
}
