Remove link/packetsocket
This change removes NetworkDispatcher.DeliverOutboundPacket.
Since all packet writes go through the NIC (the only NetworkDispatcher),
we can deliver outgoing packets to interested packet endpoints before
writing the packet to the link endpoint as the stack expects that all
packets that get delivered to a link endpoint are transmitted on the
wire. That is, link endpoints no longer need to let the stack know when
it writes a packet as the stack already knows about the packet it writes
through a link endpoint.
