GUI: поле действия и кнопка Send для отправки команд в utun

- Добавлен ETCPMON_CMD_ACTION в протокол (32 байта текст)
- В GUI добавлено поле ввода и кнопка Send правее блока Sockets
- Добавлен etcpmon_client_send_action для отправки команд
- Обработка action 'nat' в control_server: запускает NAT check для всех линков
- Сделана route_bgp_start_link_nat_check не-static
- Добавлена route_bgp_request_nat_check_all
- Исправлен баг route_ping.c (request_id -> nonce)
- Исправлена линковка tests/Makefile.am
