// parameters. If it returns the string "deny" or a Promise that resolves
// to "deny", the connection is immediately blocked. With any other return
// value (though the string "allow" is suggested for consistency), control
// is passed to other registered blockers. If no registered blockers block
// the connection (or of course if there are no registered blockers), then
// the connection is allowed.
//
// Add-ons may also use webrtcUI.on/off to listen to events without
// blocking anything:
// peer-request-allowed is emitted when a new peer connection is
// established (and not blocked).
// peer-request-blocked is emitted when a peer connection request is
// blocked by some blocking connection handler.
// peer-request-cancel is emitted when a peer-request connection request
// is canceled. (This would typically be used in
// conjunction with a blocking handler to cancel
// a user prompt or other work done by the handler)
