cmake-server: Implement ServerProtocol 1.0

Enable the initial handshake of the client to complete the connection
to the server.

The handshake sets the protocol version that client and server will
use to talk to each other. The only way to change this is to quit the
server and start over.

CMake specific information is also set during the initial handshake.
Since cmake so far never had to change basic information about any project
while running, it was decided to keep this information static and
require a restart of the cmake server to change any of these.
