ipcpd: Use 64-bit flow endpoint IDs for DT

The EIDs are now 64-bit. This makes it a tad harder to guess them
(think of port scanning). The implementation has only the most
significant 32 bits random to quickly map EIDs to N+1 flows. While
this is equivalent to a random cookie as a check on flows, the
rationale is that valid endpoint IDs should be pretty hard to guess
(and thus be 64-bit random at least). Ideally one would use
content-addressable memory for this kind of mapping.
