Fix p9 integration of flipcall.
- Do not call Rread.SetPayload(flipcall packet window) in p9.channel.recv(). - Ignore EINTR from ppoll() in p9.Client.watch(). - Clean up handling of client socket FD lifetimes so that p9.Client.watch() never ppoll()s a closed FD. - Make p9test.Harness.Finish() call clientSocket.Shutdown() instead of clientSocket.Close() for the same reason. - Rework channel reuse to avoid leaking channels in the following case (suppose we have two channels): sendRecvChannel len(channels) == 2 => idx = 1 inuse[1] = ch0 sendRecvChannel len(channels) == 1 => idx = 0 inuse[0] = ch1 inuse[1] = nil sendRecvChannel len(channels) == 1 => idx = 0 inuse[0] = ch0 inuse[0] = nil inuse[0] == nil => ch0 leaked - Avoid deadlocking p9.Client.watch() by calling channelsWg.Wait() without holding channelsMu. - Bump p9test:client_test size to medium.
