Hans de Goede 89d2a68cb7 server/reds: Send the agent a CLIENT_DISCONNECTED msg on client disconnect 
Client -> agent messages can spawn multiple VDIChunks. When this happens
the agent re-assembles the chunks into a complete VDAgentMessage before
processing it. The server only guarentees coherency at the chunk level,
so it is not possible for a partial chunk to get delivered to the agent.

But it is possible for some chunks of a VDAgentMessage to be delivered to
the agent followed by a client to disconnect without the rest of the
VDAgentMessage being delivered!

This will leave the agent in a wrong state, and the first messages send to it
by the next client to connect will get seen as the rest of the VDAgentMessage
from the previous client.

This patch sends the agent a new VD_AGENT_CLIENT_DISCONNECTED message from the
VDP_SERVER_PORT, on which the agent can then reset its VDP_CLIENT_PORT state.

Note that no capability check is done for this, since the capabilities are
something negotiated between client and agent. The server will simply always
send this message on client disconnect, relying on older agents discarding the
message since it has an unknown type (which both the windows and linux agents
already do).
