When speculative enqueue fails and a buffer needs to be moved to a new
node queue the original buffer is not correctly removed from the
original queue so buffer get send for transmit and encryption at the
same time. This issue will only be hit with the double loop so low
throughput traffic like pings will not hit the issue. This code path is
also only hit when the feature flag is enabled so will not be hit by
normal traffic
Patch also reorgnizes code to reduce number of branches in the interface
output node loop.

In some cases, the packet header size with IPv6 and a tunnel can
overflow the buffer used for packet tracing. This patch increases
this buffer a little to avoid truncated header information in the
trace.

The current mechanism for setting up arp-input and ip6-discover-neighbor
output nodes for interfaces using their interface link up/down callback
function is inefficient and has potential timing issue, as observed for
bonded interface. Now both nodes will setup output interface sw_if_index
in the the sw_if_index[VLIB_TX] field of current packet buffer and then
use the interface-ouput node to tx the packet.
One side effect is that vlib_node_add_next_with_slot() needs to be
modified to allow the same output node-id to be put at the specified
slot, even if another slot contain that same node-id already exist. This
requirement is caused by BVI support where all loopback interfaces set
up as BVIs will have the same output node-id being l2-input while, for
output-interface node, the output slot must match the hw_if_index of the
interface.
