Functions
int	add_bytes_to_msg (NETW_MSG *msg, const void *bytes, size_t len)
	Add a binary blob to the message (clean alias for a raw N_STR payload, distinguishes binary data from character strings at call sites).
int	add_int_to_msg (NETW_MSG *msg, int value)
	Add an int to the int list int the message.
int	add_nb_to_msg (NETW_MSG *msg, double value)
