Switch to varlink as IPC protocol

This is a lot! Whole new design on top of a statefult varlink interface.

You can now handle multiple request response cycles over a single
connection.

The error responses are lot more refined than just status codes with
optional messages and finally part of the protocol.

TODO: A lot of error handling needs to be improved.
