When a new link is added, the link state update will be sent before
the database update, so the network is a little bit more quickly
aware. This improves odds of the DHT successfully enrolling at its
first attempt, reducing bootstrap time of a network.

There was a bug where the hash selection for the local, raptor and
ethernet IPCPs was not passed correctly, so they were using a wrong

The link-state algorithm will now quickly recalculate for link
additions (but not for removals, for stability). Upon notification of
a new link, the DHT will wait for a brief moment to enroll.
This reduces enrolment for large networks by some orders of magnitude.

The FRCT kept only a left window edge in the receiver connection
window, however, it needs to keep track of the left window edge
(highest ACK'd sequence number) and the highest delivered sequence
number, so it can delay ACKs that cannot be piggybacked. TCP
recommends at most 500 ms for delayed ACKs (probably good to keep it
near half of RTO).

Since the Ethernet IPCP now has multiple reader threads it was

threads to block on the recv call. This makes the socket non-blocking
