Commit Message

netty: reset stream when trailers arrive with END_STREAM unsent (#13079)

`transportHeadersReceived()` already reset the stream when trailers
arrived before the client finished sending, but it used
`isOutboundClosed()` as a stand-in for "END_STREAM has been sent". Those
differ whenever END_STREAM is still waiting on flow control: the
application has half-closed, yet the frame sits in the remote flow
controller. If the server responded and closed the call without reading
the rest of the request, it stops returning window, so END_STREAM can
never be written and neither side resets the stream.

Decide the reset on the HTTP/2 stream's local state instead, which is
only closed once END_STREAM has actually been written.

Fixes https://github.com/grpc/grpc-java/issues/13078.
