2e08354ce1 Rename Stream to VideoStream
To prevent confusion between Stream (a video stream) and RedStream (a
generic data stream between client and server), change the name to
VideoStream to be more explicit about what it is.

a5aa2a2261 Use standard "Red" namespace
The objects RedsStream and RedsSASL are currently using the namespace
"Reds" rather than the standard "Red" namespace used throughout the rest
of the project. Change these to be consistent. This also means changing
method names and some related enumeration types.

The files were also renamed to reflect the change:
  reds-stream.[ch] -> red-stream.[ch]

a8afcfef6b stream-device: Limit sending queue from guest to server
Do not allow the guest to fill host memory.
Also having a huge queue mainly cause to have a higher video
latency.

82769e5dfc stream-device: Start supporting resetting device when close/open on guest
When guest close the device the host device has to be reset too.
This make easier to restart the guest device which can happen in case
of reboot, agent issues or if we want to update the agent.

9ea16ff4a0 stream-channel: Do not show an empty blank screen on start
Start showing something when we have a surface and stream
instead of showing a blank screen which is now not useful.
Was useful for debugging purposes to understand that the
new channel was sending messages correctly to client and
client could handle them.

633e04b40c stream-channel: Support client connection/disconnection
When a new client is connected we must restart the stream so new
clients can receive correct data without having to wait for the
next full screen (which on idle screen could take ages).
On disconnection we should tell the guest to stop streaming
not wasting resources to stream not needed data.

60104d818c stream-device: Handle streaming data from device to channel
Handle stream data from device sending to the channel.
The StreamChannel will forward the data to the clients using standard
DisplayChannel messages, and will create and destroy streams as
necessary.
