This removes the _DEFAULT_SOURCE definition in the endian header as it
should not be there. This avoids double and conflicting definitions.

Previously there was a separate function per routing algorithm
selection, when in fact the algorithms all take as input a graph and
output a routing table, making it possible to place them in a single
function.

The management flows were considering every event to be a FLOW_PKT
event, when in fact it could also be a flow down or up event,
resulting in indefinite reads.

Commit a3903da659e introduced sequence number for the LSAs to make it
more robust, but the check was not done properly, and the seqno was
always changed regardless of whether it was an old LSA or not.

This enhances the irm connect and irm disconnect command to allow
creating connections between IPCPs based on wildcard matching for the

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
up and down events, and flag the connection up or down if needed.

The SIOCGIFMTU command uses the ifr struct, which is a union, so it
