The callback that is invoked when the connection to the PNS Agent has been closed.
#include <bbpush/push_service.h>
typedef void(* push_connection_close_callback_t)(push_service_t *ps);

When this happens, the application or service needs to re-establish the connection with the PNS Agent by calling push_service_get_fd() periodically until push_service_get_fd() returns a valid file descriptor.
Call push_service_set_connection_close_callback() to register this callback.
