lib, ipcpd, irmd: Register hash instead of name

All information passed over the IRMd/IPCP boundary for using IPC
services (flow allocation, registration) is now hashed. This
effectively fixes the shared namespace between DIFs and the IRMDs.

This PR also fixes some API issues (adding const identifiers),
shuffles the include headers a bit and some small bugs.
