protocol-native: use props in server and data

Browse source 
Add props to the protocol_data and server. Instead of storing the
server_info, just add the relevant properties for the server to the
props.

When we get a new client, we can simply copy the server props to the
client props. This makes it possible to create specific servers later
that create clients with specific properties.

Use a subset of the context properties to create servers. We only need
the CORE_NAME for now.
