http2: adjust flow control on open streams when processing SETTINGS
The http2 spec says:
> When the value of SETTINGS_INITIAL_WINDOW_SIZE changes, a receiver
> MUST adjust the size of all stream flow-control windows that it
> maintains by the difference between the new value and the old value.
We didn't do this before, and it never mattered until
https://golang.org/cl/25362 for golang/go#16519 because we always knew
the peer's initial window size.
Once we started writing request bodies before hearing the peer's
setting (and thus assuming 64KB), it became very important that this
TODO was done. Should've done it earlier.
More details in the bug.
Updates golang/go#16612 (fixes after bundle into std)
