/**
 * @brief Stroke is a configuration and control interface which
 * allows other processes to modify charons behavior.
 * 
 * stroke_t allows config manipulation (as whack in pluto). 
 * Messages of type stroke_msg_t's are sent over a unix socket
 * (/var/run/charon.ctl). stroke_t implements the connections_t
 * and the policies_t interface, which means it acts as a 
 * configuration backend for those too. stroke_t uses an own
 * thread to read from the socket.
 * 
 * @warning DO NOT cast stroke_t to any of the implemented interfaces!
 * stroke_t implements multiple interfaces, so you must use
 * stroke_t.interface_xy to access the specific interface! You have
 * been warned...
 * 
 * @todo Add clean thread cancellation
 * 
 * @b Constructors:
 * - stroke_create()
