@brief Sends a UDP message to remote end point with non-continous payload
@pre ((sock != NULL || remote != NULL))
@param[in] sock A UDP sock object. May be NULL.
A sensible local end point should be selected by the
implementation in that case.
@param[in] snips List of payload chunks, will be processed in order.
May be NULL.
@param[in] remote Remote end point for the sent data.
May be NULL, if @p sock has a remote end point.
sock_udp_ep_t::family may be AF_UNSPEC, if local
end point of @p sock provides this information.
sock_udp_ep_t::port may not be 0.
@param[out] aux Auxiliary data about the transmission.
May be NULL, if it is not required by the application.
@return The number of bytes sent on success.
@return -EADDRINUSE, if sock has no local end-point or was NULL and the
pool of available ephemeral ports is depleted.
@return -EAFNOSUPPORT, if remote != NULL and sock_udp_ep_t::family of
@p remote is != AF_UNSPEC and not supported.
@return -EHOSTUNREACH, if @p remote or remote end point of @p sock is not
reachable.
@return -EINVAL, if sock_udp_ep_t::addr of @p remote is an invalid address.
@return -EINVAL, if sock_udp_ep_t::netif of @p remote is not a valid
interface or contradicts the given local interface (i.e.
neither the local end point of sock nor remote are assigned to
SOCK_ADDR_ANY_NETIF but are nevertheless different.
@return -EINVAL, if sock_udp_ep_t::port of @p remote is 0.
@return -ENOMEM, if no memory was available to send @p data.
@return -ENOTCONN, if remote == NULL, but @p sock has no remote end point.
