Expand description

Copies bytes both ways until one side closes, then returns.

Used for the post-101 tail of an upgraded connection. copy_bidirectional rather than two hand-rolled loops: it already handles the half-close case where one direction ends while the other still has data, which is the case a naive select! loop truncates.
