/**
* @brief Creates a new menu object.
*
* The handler function should be prototyped as:
*
* public <function>(menu, id, item)
* menu - Menu resource identifier.
* id - Client the menu is being acted upon.
* item - Item the client selected. If less than 0, the menu was
* cancelled and the item is a status code. menu_display
* should never be called immediately if the item is a status
* code, for re-entrancy reasons.
*
* The handler function should always return PLUGIN_HANDLED to block
* any old menu handlers from potentially feeding on the menu, unless
* that is the desired functionality.
*
* @param title Title the menu should use.
* @param handler Name of the handler function. The function will be invoked
* once and only once to every menu_display() call.
* @param ml Unused (should be 0).
* @return Menu resource identifier which must be destroyed via
* menu_destroy(). All menus are destroyed when the plugin
* unloads.
* @error Function name not found.
