bgpd: Increment version number even when no data is sent
When an update group decides to not send a prefix
announcement because it has not changed, still increment
the version number. Why? To allow for the situation
where you have say 2 peers in 1 peer group and shortly
after they come up a 3rd peer comes up. It will be
placed into a separate update group and could be
coalesced down, when it finishes updating all data
to it. Now imagine that a single prefix changes at
this point in time as well. Then first 2 peers may
decide to not send the data, since nothing has changed.
While the 3rd peer will and since the versions numbers
never match they will never coalesce. So when the decision
is made to skip, update the version number as well.

ospfd, ospf6d: perform GR consistency check only when necessary

This optimization reduces unnecessary computations when the

ospf6d: update DR election to handle GR corner case
Consider the case where a DR router is performing a graceful restart,
and all neighbors attached to the DR network have their priorities
set to zero.
According to RFC 3623, the router should reclaim its DR status while
coming back up once it receives a Hello packet from a neighbor
listing the router as the DR, and the associated interface is in
Waiting state.
The problem arises when the DR election starts. Since the router
is already elected the DR, and no BDR will be elected (since all
neighbors have their priorities set to zero), the AdjOk event won't
be triggered at the end of the DR election as it would normally
happen. That causes all neighbors reachable over the broadcast
interface to get stuck in the 2-Way state.
Fix this corner case by always triggering the AdjOk event at the
end of the DR election process when a GR is in progress. Triggering
the AdjOk event when not necessary should never be a problem as
the neighbor FSM is already prepared to deal with that.
