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.

This sets the CRC check to be disabled by default, since it greatly
hampers performance and is almost never needed.

The QoS specs were defined in the source file instead of in the header
file, which resulted in uninitialized structs being used, which gave
rise to weird behavior in the library.

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).

The flow allocator now passes the full qos specification to the
endpoint, instead of just a cube. This is a more flexible
architecture, as it makes QoS cubes internal to the layers.

Since the Ethernet IPCP now has multiple reader threads it was
possible that both exit the select call, which caused one of the two
threads to block on the recv call. This makes the socket non-blocking
so that the recv call simply fails.

This will add a sequence number to the Link State Advertisements so
that upon receiving a LSA we can check if we need to forward the LSA
or not. If we already have the LSA with the received seqno in the LSDB
we do not forward it. This allows for setting up a management network
that has loops since the spanning tree upon which the LSAs are sent is
pruned on every hop.

The DT component was flagging a connection as down and passing the fd
that was down. Of course the other components expect a connection
instead of just a fd. Now the connection manager will listen to flow
