http2: Send WindowUpdates when remaining bytes are below a threshold

This rolls-forward CL 150197 with an added fix for
TestProtocolErrorAfterGoAway.

Rather than send a WindowUpdate on every chunk of bytes read, allow them
to collect until we go past half the configured window size. Once the
threshold is reached, send a single WindowUpdate to reset the amount
back to the maximum amount configured.

Fixes golang/go#28732
