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.

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.

in bgp_io.c upon packet read of some error we are storing
the peer pointer on a thread to call bgp_packet_process_error.
In this case an event is generated that is not guaranteed to be
run immediately. It could come in *after* the peer data structure
is deleted and as such we now are writing into memory that we
no longer possibly own as a peer data structure.
Modify the code so that the peer can track the thread associated
with the read error and then it can wisely kill that thread
when deleting the peer data structure.

When bgp receives the admin distance from a redistribution statement
let's store that distance for later usage.

In eusure_vrf_tovpn_sid, there is a check to ensure not to select both
SID index and SID auto mode. But, this current check is wrong and not
meaningful.
