If an imported BGP is configured after BGP updates have been
received, then BMP will not detect those updates in the
monitor messages.
Syncronisation is also needed for separate instances.
For each imported bgp instance, syncronisation is re-done
for monitored afi/safis for ALL available instances.

- when configuring an imported view

Add the emission of a loc-rib peer up event for an imported bgp instance
at import-vrf configuration. Add a test to control in the BMP collector
that the peer up message is the one from that BGP instance.

Add a configuration command to import BGP information from
another BGP instance. Specifically, it should be possible for
a user to have a BMP instance configured on the default VRF,
and be able to import the VRF information from the other BGP
VRF instances.

added bmp bgp peer for vrfs
added peer up vrf in bmp peer up state
added vrf state in bmpbgp
added safe bmp_peer_sendall : bmp_peer_sendall_safe
changed bgp_open_send to call new bgp_open_make
bgp_open_make creates a bgp open packet, now used in bmp for peer up vrf
added hook and call to bgp instance state
vrf peer state is recomputed when interfaces (including vrf itf) go up / down
and when it gets created or removed

Some wireshark versions can not decode the experimental
bmp stat code. This may also be the case for some collectors.
Add a vty command to be able to disable bmp to sending
those values.

With current release, forcin the source ip address when setting up a BMP
connection is not possible.
The need is to add an extra parameter for the following vty command:
router bgp 65500
bmp targets AAA
bmp connect 2.2.2.2 port 666 min-retry 100 max-retry 700
bmp connect 2:2::2:2 port 666 min-retry 100 max-retry 700 [source-interface lo1]

Back when I put this together in 2015, ISO C11 was still reasonably new
and we couldn't require it just yet. Without ISO C11, there is no
"good" way (only bad hacks) to require a semicolon after a macro that
ends with a function definition. And if you added one anyway, you'd get
"spurious semicolon" warnings on some compilers...
With C11, `_Static_assert()` at the end of a macro will make it so that
the semicolon is properly required, consumed, and not warned about.
Consistently requiring semicolons after "file-level" macros matches
Linux kernel coding style and helps some editors against mis-syntax'ing
these macros.

When sending BMP messages for a status change event for a peer whose NHT
has failed, we were sending a Peer Down Reason Code of 1 (Local system
closed, NOTIFICATION follows) with no NOTIFICAION PDU (because there was
none). This is wrong. Also, the reason code of 1 is semantically off, it
should be 2 (Local system closed, FSM event follows).
This patch:
- adds definitions of all BGP FSM event codes per RFC4271
- changes the BMP reason code emitted when a peer changes state due to
NHT failure to 2 and encodes FSM event 18 (TcpConnectionFails)
- changes the catch-all case where we have not yet
implemented the appropriate BMP response to indicate reason code 2
with FSM event 0 (no relevant Event code is defined).
These changes ought to prevent the BMP session from being torn down due
to an improperly formatted message.

This implements BMP. There's no fine-grained history here, the non-BMP
