Add support for X-SS-Connect-Data in RTSP SETUP for control stream
...
This allows the host to provide a 32-bit integer that will be sent
in the data of the ENet connect event, similar to X-SS-Ping-Payload
for video and audio.
The host can use this data to uniquely identify a client when IP
addresses are not stable across the various separate connections,
such as when the client is behind a Carrier-Grade NAT.

Bind our UDP sockets to the same local address used by RTSP handshake
...
This means we can ensure a consistent local address for our outgoing PING
traffic to keep the UDP flows alive without having to call connect() which breaks
with multi-homed hosts on GFE and Sunshine v0.20 and earlier.

Invoke control stream callbacks on a separate thread
...
Time spent processing client callbacks would contribute to increased control stream latency,
which means higher RTTs, more lengthy waits before retransmissions, and higher client-reported
network latency stats.
