bb5ac95928 Restrict trace store client to only resolve IPv4 addresses. Previously the resolve would look up IPv6 addresses for the given host leading to stalls.

9bc39ddbb2 Shifted the store frontend to another port so as to avoid collision with old-school Unreal Insightses.

5be4185e2a Versioned the end points that the trace store server and client communicate over. This will be useful as I shift to running the trace store in a separate process who's lifetime I've less control over.

4bf9cfa79a Call select() on a socket before making a blocking call to recv(). Calls to recv() that are waiting for data may not return even if the socket is closed. This can result in a technical hang where Insights waits on Trace waiting on a socket that was closed. This way we only call recv() when we know there is data to read, and the select()+timeout combo correctly detects to the close().

8a6a773e17 Trace data is a stream and communication is one way. It is implemented this way to share code between sending trace data over the wire and writing it to a file. Because there's no ping/pong we can end up with a half-open TCP connection if the other end doesn't close its socket. So we'll enable keep-alive on the socket and set a short timeout (default is 2hrs).

bcda0febbe Cancel the timeout tick when accepting a connection to read trace data from a relay. Otherwise the timeout fires causing an extra read, the loss of a page of trace data, and eventually a segfault or assert.
