Configuration manager with DCF in object 0x1F22 rewritten almost from scratch.
1. The boot-up message from a device starts a verification of entries
2. If all entries matches the node is started
3. If an entry differs the whole dcf is written and a save is done
4. A reset is send to the node
5. If several boot-up are received at the same time they will be managed one
by one thus only one free sdo client is needed for the whole process.
