Returns the number of DATA payload in bytes received without
WINDOW_UPDATE transmission for the stream |stream_id|. The local
(receive) window size can be adjusted by
submitWindowUpdate. This function takes into account
that and returns effective data length. In particular, if the
local window size is reduced by submitting negative
window_size_increment with submitWindowUpdate, this
function returns the number of bytes less than actually received.
