ipcpd: Integrate raptor into ouroboros 0.8

The raptor code is refactored to completely remove reduntant code
relating to addresses. The dependency on the google protocol buffers
is removed. The build system will only build raptor if the relevant
kernel module is found on the system. The irm tool and the relevant
documentation are updated.
