if advertisement with SID structure Sub-Sub-TLV, we need to transpose
SID, so added transpose operation into bgp_update.

draft-ietf-bess-srv6-services-07 defines new SID structure Sub-Sub-TLV.
This patch adds SID structure information to bgp_attr_srv6_l3vpn. This
patch also defines default SID stucture used by following patches.

Current implementation of SRv6 SID allocation algorithm sets most least
2 bytes. But, according to RFC8986, function bits is located in the next
to locator. New allocation alogirithm respects this format.

Fix CI Failure test_ospf_type5_summary_tc45_p0
Problem Statement:
==================
Summarised LSA is not flushed in OSPFv2 in below scenario:
1. Configure summary-address in ospfv2
2. redistribute static and connected.
3. Check the LSAs are received on neighbor.
4. Now remove all OSPFv2 configs, so neighbor will still have the summarised LSA.
5. Configure router ospf with redistribute static and connected.
6. Check the DB, summarised LSA is present although the configuration is not present.
7. Now configure the summary-address and remove the configuration after sometime.
8. The summarised LSA will be still present.
RCA:
==================
When self originated LSA is received from the neighbor and that
LSA is summarised one, the LSA is refreshed but a flag is not set
due to which it was not able to remove it later.
Fix:
==================
Set the originated flag when refreshing summarised LSA.

When NHRP registers to zebra to receive link layer events related to
gre interfaces, then it is interested in receiving also RTM_GETNEIGH

The code to output during a `show run` is missing for both
the expire_interval and the retry_interval in rpki.
Let's add it in so the end user can see what they
are set to if not set to the default.

We are prematurely stopping processing of bgp_path_info's
when bgp_update returns a -1. The only place that this
happens when we cross some prefix limit. But we still
need to continiue processing other nodes in the list too.

The processing was looping over all bgp instances then
over all peers then over all safi's to find a match
for a prefix received in order to validate it.
Suppose you have 100 peers each sending you the same
prefix. This code will cause it to look at each node 100
times since we look at for each peer. This is especially
egregarious because we never ever do anything with the peer
when we are looping over them.
Remove the peer loop, significantly reduce processing.

Problem seen where if "set aspath-prepend last-as" configured and
applied outbound, we prepend the peer's asn which causes our self-
originated routes to be denied.
