This commit addresses an issue that happens when using bgp
peering with a rr client, with a received prefix which is the
local ip address of the bgp session.
When using bgp ipv4 unicast session, the local prefix is
received by a peer, and finds out that the proposed prefix
and its next-hop are the same. To avoid a route loop locally,
no nexthop entry is referenced for that prefix, and the route
will not be selected.
When the received peer is a route reflector, the prefix has
to be selected, even if the route can not be installed locally.

Rather than running selected source files through the preprocessor and a
bunch of perl regex'ing to get the list of all DEFUNs, use the data
collected in frr.xref.
This not only eliminates issues we've been having with preprocessor
failures due to nonexistent header files, but is also much faster.
Where extract.pl would take 5s, this now finishes in 0.2s. And since
this is a non-parallelizable build step towards the end of the build
(dependent on a lot of other things being done already), the speedup is
actually noticeable.
Also files containing CLI no longer need to be listed in `vtysh_scan`
since the .xref data covers everything. `#ifndef VTYSH_EXTRACT_PL`
checks are equally obsolete.

Use the IP addr of type2/macip routes only for the hash/key
of the VNI table and carry the MAC in a path_info_extra attribute.
There is exists situations that can be hit during extended MAC mobility events
where two MACs could be pointing to the same IP in our global table. It
is requires very specific timings.
When that happens, BPG would (because we key'd on both MAC and IP)
install both into it's VNI table as separate entries, but zebra only
knows/needs to know about a single IP -> MAC relationship for it's VNI
table's type2 routes. So it was compleletly undeterministic which one
zebra would end up with in these timing situations.
With these changes, we move BGP's VNI table to key'd the same as Zebra's
and now a single IP will have multiple path_info's with a path_info_extra
that is carrying the MAC info for each path.
BGP will then run best path to deterministically decide which one to send to
zebra during the occasions where there exist's two possible MACs.

RFC4364 describes peerings between multiple AS domains, to ease
the continuity of VPN services across multiple SPs. This commit
implements a sub-set of IETF option b) described in chapter 10 b.
The ASBR to ASBR approach is taken, with an EBGP peering between
the two routers. The EBGP peering must be directly connected to
the outgoing interface used. In those conditions, the next hop
is directly connected, and there is no need to have a transport
label to convey the VPN label. A new vty command is added on a
per interface basis:
This command if enabled, will permit to convey BGP VPN labels
without any transport labels (i.e. with implicit-null label).
restriction:
this command is used only for EBGP directly connected peerings.
Other use cases are not covered.

BGP SoO is a tag that is appended on BGP updates to allow a peer to mark
a particular peer as belonging to a particular site. In certain MPLS L3 VPN
configurations, the BGP AS-Path may not provide the granularity needed
prevent a loop in the control-plane. With this in mind, BGP SoO is designed
to fill this gap and prevent a routing loop that may occur.
If we configure for example, `neighbor soo 65000:1` at PEs, routes won't be
announced between CPEs if soo matches. This is especially needed when using
as-override or allowas-in.
Also, this is the automated way of the same behavior as configuring route-maps
for each peer like:
```
bgp extcommunity-list cpe permit soo 65000:1
!
route-map cpe permit 10
set extcommunity soo 65000:1
...
route-map cpe deny 10
match extcommunity cpe

Start using mpls_lse_encode/mpls_lse_decode, that is endian-aware, because
we always use host-byte order, should use network-byte.

in bgp_nlri_parse_ip there is a `sanity` check to ensure
that the prefix length as specified by the packet
will fit inside of a `struct prefix` correctly. The problem
here of course is that this is only v4 / v6 unicast/multicast
parsing and the bytes will never be more than 16, but we are copying
into a part of the struct prefix that is only 16 bytes, but with
this check the length may be up to 47 bytes( but not really possible ).
Limit the size check to at most 16 bytes (since we are only handling
v4 or v6 addresses here )

The maxpaths same_clusterlen value was a uint16_t
with a single bit being used. No other values are
being stored. Let's remove the bitfield and simplify
to a bool.

The logic to unlock dest if iteration completed without iterating the
entire node was flawed. Specifically, if iteration terminated due to
`gr_deferred == 0` then the node would not get unlocked.
This change takes into account the fact that dest will be NULL only in
the case when the entire table was iterated and all nodes were already
unlocked. In any other case, it needs to be unlocked.

When `all` is specified BGP pointer is always NULL, we need to iterate over
all instances separately.

Commit: ea47320b1d
Modified the bgp_clear_stale_route function to have
better indentation, but in the process changed some
`continue;` statements to `break;` which modified
the looping and caused stale paths to not always be
removed upon an update.
To reproduce: A ---- B, setup with addpath and GR
One side has a prefix with nhop1 and nhop2, kill one
side and then resend the same prefix with nhop3,
paths nhop1 and 2 become stale and never removed.
Code inspection clearly shows that that `continue`
statements became `break` statements causing the
loop over all paths to stop prematurely.
The fix is to change the break back to continue
statements so the loop can continue instead of
stopping.
