Add initial seamless mode supportseamless-mode

Seamless mode is a way to use guest applications directly on the
client system desktop side-by-side with client applications.

Add a new capability VD_AGENT_CAP_SEAMLESS_MODE. It indicats ability
to handle following seamless mode messages.

Add a message VD_AGENT_SEAMLESS_MODE. It is used to enable/disable
sending VD_AGENT_SEAMLESS_MODE_LIST messages. It is sent from client
to agent once the change is needed.

Add a message VD_AGENT_SEAMLESS_MODE_LIST. It is used to sent a list of
visible rectangle areas. It is sent periodically from agent to client
with every list change.
