ospf6d: "clear ipv6 ospf6 process" command
Adding the "clear ipv6 ospf6 command" . It resets
the ospfv3 datastructures and clears the database
as well as route tables. It resets the neighborship
by restarting the interface state machine.
If the user wants to change the router-id, this
command updates the router-id to the latest static
router-id and starts the neighbor formation with
the new router-id.

ospf6d: fix duplicated packet read
When OSPFv3 router is configured in both default and non-default VRFs,
every packet destined to a non-default VRF is read twice. This makes it
impossible to establish neighborship because every DbDesc packet is
treated as duplicated and we end up infinitely exchanging DbDescs.
We should drop packets received in the default VRF if an interface we
received it on is bound to another VRF.

build: add `-Werror` to xrelfo log format warnings
Adding a `\n' should now produce a warning. Controlled by `-Werror` so
if you're doing a dev build and it's warning about some `prefix2str`
that should be converted to `%pFX`, you can turn off `-Werror` to fix it
later like with all other warnings.

tools: limit bgp route-maps to direct changes only
When using frr-reload.py to modify a bgp neighbors route-map
the code was doing this:
a) deleting the previous route-map: `no neighbor XX route-map YY (in|out)`
b) Adding the new route-map back in `neighbor XX route-may ZZ (in|out)`
Now imagine that we have an outgoing route-map that we are changing
and the reload is large because of a large number of lines in frr.conf
Item (a) will happen. BGP will immediately start sending all local
routes. At some point in time in the future (b) will be applied.
This of course causes a withdraw but for a short amount of time we
are leaking unintended routes. This is bad for several reasons
not 1) route churn upstream, 2) we might influence traffic to go the
wrong way. 3) if upstream has a maximum-prefix command the routes
being sent might trip its circuitry and shutdown the peer entirely
not even allowing you to get to (b).

isisd: fix interface ldp-sync configuration
There are two checks done when configuring ldp-sync on an interface:
- interface is not a loopback
- interface is in the default VRF
Both checks are incorrectly done using the operational data.
The second check can be done using only config data - do that.
The first check can't be done using only configurational data, but it's
not necessary. LDP sync code doesn't operate on loopback interfaces
already. There's no harm in allowing this to be configured.

lib: remove vrf-interface config when removing the VRF
If we have the following configuration:
```

exit-vrf
!
interface red vrf red

```
And we delete the VRF using "no vrf red" command, we end up with:
```
interface red
smth
```
Interface config is preserved but moved to the default VRF.
This is not an expected behavior. We should remove the interface config
when the VRF is deleted.
ospfd: External lsa handling in opaque capabilities enable/disable
Description:
When opaque capability disabled/enabled , all the self-originated lsa will be
flushed and it will make the neighbours to renegotiate.
But here, external lsas are not being re-originated after negotiation
Fix:
Refresh/re-originate external lsas(Type-5 and Type-7) explicitly after
re-negotiation.

ospf6d: Release last dbdesc packet after router dead interval
During the database description exchange process, the slave
releases the last dbdesc packet after router_dead_interval.
This was not implemented in the code.
I have written the function ospf6_neighbor_last_dbdesc_release,
which releases the last dbdesc packet after router_dead_interval.
This change was required as per the conformance test 13.11:
In state Full reception of a Database Description packet from
the master after this interval (RouterDeadInterval) will
generate a SeqNumberMismatch neighbor event.
