ipcpd: normal: Add operations to get and set the PCI
This adds the operations needed in the normal IPCP to get and set the
Protocol Control Information. It allows to allocate or release space
in the current DU. The struct pci can be serialized into newly
allocate space. Vice versa, a struct pci can be deserialized given a
DU. It allows for decreasing the TTL in the DU and for calculating the
CRC32. The TTL and CRC32 can now be selected when creating a new DIF.
