> VirtualSocketServer out-of-order issue with closing TCP sockets
> 
> https://webrtc-codereview.appspot.com/41449004 added a TURN TCP
> allocation release test which was disabled as it triggered an assert
> in the turnserver.
> 
> This was caused by VirtualSockerServer delivering the last TCP packet
> after closing the connection. Calling
>     VirtualSocketServer::SendTcp
> and
>     VirtualSocket::Close
> from TestTurnTCPReleaseAllocation led to the following order of
> messages in VirtualSocket::OnMessage:
>     MSG_ID_DISCONNECT
>     MSG_ID_PACKET
> 
> This is out of order and triggers an assert in turnserver.cc since the
> socket from which the message arrives has already been discarded,
> subsequently breaking the test.
> 
> In VirtualSocketServer::Disconnect the MSG_ID_DISCONNECT is posted to the
> msg_queue immediately, thus getting ahead of any (slightly delayed)
> actual packets.
> 
> Maybe PostAt(network_delay_ + 1, ...) would be better?
> 
> Re-enables TestTurnTCPReleaseAllocation.
