the bgp version was not updated appropriately and
when zebra received the message it did not properly
read it.

FRR should create a bnc per peer. Not have
one's that write over others. Currently when
FRR has multiple Interface based peering, BGP wa
creating a single BNC. This is insufficient in that
we were accidently overwriting the one LL with other
data. This causes issues when there are multiple and
there is weird starting issues with those interfaces
that you are peering over.

Just convert all uses of thread_cancel to THREAD_OFF. Additionally
use THREAD_ARG instead of t->arg to get the arguement. Individual
files should never be accessing thread private data like this.

Let's just use THREAD_OFF consistently in the code base
instead of each daemon having a special macro that needs to
be looked at and remembered what it does.

A new command is available under SAFI_MPLS_VPN:
With this command, the BGP vpnvx prefixes received are
not kept, if there are no VRF interested in importing
those vpn entries.
A soft refresh is performed if there is a change of
configuration: retain cmd, vrf import settings, or
route-map change.

The "struct bgp" variable names in the mplsvpn bgp code do not
explicitly say whether they refer to a source or destination BGP
instance. Some variable declarations are commented out with "from" and
"to" but this does not avoid confusion within the functions. The names
of "struct bgp" variables are reused in different functions but their
names sometimes refer to a source instance and sometimes to a
destination instance.
Rename the "struct bgp" variable names to from_bgp and to_bgp.

The GCC extended printf format checking plugin runs into some GCC
shortcomings regarding casts on printf function parameters. While this
can be fixed with a small GCC patch, patching GCC is "nontrivial" to say
the least. Luckily, it happens that this is /almost/ not an issue for
the FRR source base.
Since we fix SA "misunderstandings" too, let's just fix places where the
format checking plugin runs into this limitation to keep things working
extra smoothly.
(It's not a huge effort either, these two spots in bgpd are the only
places that trigger the plugin limitation, and it's been "clean" before
that for more than a year if my memory is right.)
