[PATCH spice-server] red-worker: Introduce RedWorkerMessageGlDraw structure

[Frediano Ziglio <fziglio@xxxxxxxxxx>]

All RedWorker messages starts with RedWorker except
SpiceMsgDisplayGlDraw.
For coherence introduce a RedWorkerMessageGlDraw structure
holding just SpiceMsgDisplayGlDraw. This also allows possible
extensions.
