* p2p/conn: FlushStop. Use in pex. Closes #2092 In seed mode, we call StopPeer immediately after Send. Since flushing msgs to the peer happens in the background, the peer connection is often closed before the messages are actually sent out. The new FlushStop method allows all msgs to first be written and flushed out on the conn before it is closed. * fix dummy peer * typo * fixes from review * more comments * ensure pex doesn't call FlushStop more than once FlushStop is not safe to call more than once, but we call it from Receive in a go-routine so Receive doesn't block. To ensure we only call it once, we use the lastReceivedRequests map - if an entry already exists, then FlushStop should already have been called and we can return.
