The DHT is now a proper directory policy instead of a unicast IPCP
component.

This makes the DHT a single directory implementation and moves it to
the stack (init/fini instead of create/destroy). This is a step
towards making it a directory policy, in line with our other policy
implementations.

This add an ouroboros/pthread.h header that wraps the
pthread_..._unlock() functions for cleanup using
pthread_cleanup_push() as this casting is not safe (and there were
definitely bad casts in the code). The close() function is now also
wrapped for cleanup in ouroboros/sockets.h.
This allows enabling more compiler checks.

The connection manager and enrolment components of the unicast and
broadcast IPCP have a lot in common, as conjectured in the paper. The
initial implementation of the broadcast IPCP just duplicated the
code. This moves the shared functionality to common ground.

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.

The DT will now post all packets for N+1 flows through the flow
allocator component. This means that N+1 flows can be monitored
through the flow allocator stats, and N-1 flows through the DT stats.
The DT component still keeps stats for the local components (FA and
DHT), but this can be removed once the DHT has its own RIB
output.
The flow allocator show statistics for
Sent packets: total packets that were presented for sending
on this specific flow
Send failed: packets that were unable to be sent
Received packets: total packets that were presented by the DT component
on this specific flow
Received failed: packets that were unable to be delivered
These stats are presented as both packet counts and byte counts. To
know how many were successful, the values for failed need to be
subtracted from the values for total.

This completes the renaming of the normal IPCP to the unicast IPCP in
the sources, to get everything consistent with the documentation.
