Detail fixes: 1. Add resize support in shadow framework layer 2. Enhance X11 implementation to detect desktop resolution change 3. Fix the subRect feature. It seems not completely finished and it looks incompatible in different source code. Fix it to be consistent in all source code as following: a. The subRect is only awared in framework layer, subsystem implementation should not be aware of it. It only take effect at shadow_client and corresponding shadow_input. b. The screen and surface should only represent a monitor screen. They don't need to consider subRect feature. 4. A lobby should be alternative image shown to client when the client is not 'mayView'. We don't need to have seperate lobby for each client, move it into server structure as 'another surface' 5. Fix display handle leak in enum monitor of X11 6. Suppress BadMatch Error while capturing the image
