00dffa8cde lib: add frr_with_mutex() block-wrapper
frr_with_mutex(...) { ... } locks and automatically unlocks the listed
mutex(es) when the block is exited.  This adds a bit of safety against
forgetting the unlock in error paths & co. and makes the code a slight
bit more readable.

Conver these functions:

d4c7ac0105 zebra: Added a few more information in route_entry while dumping
re->nexthop_num and re->nexthop_active_num are calculated while rib
processing. Also It helps in encoding the ZAPI message.
It's good to dump these parameters also, when the system is in
abnormal state.

fd267f0808 zebra: Correct /32 addr del with broadcast set
Since we are now away from the dual use of the destination field, there
is no need to single out /32 addresses as broadcast. This was bugged
anyway, since the same /32 criteria was used for IPv6 addresses as well,
when `connected_check_ptp` is called in `connected_delete_ipv6`.

In BGP enable the redistribute connected. Now Zebra will not send
the route corresponding to IPV4 link local address. Now made this
interface down and up. Zebra sends the route to BGP.
Zebra should not send this route to BGP.
This Fix would make the behaviour consistent and would not send the

ea7ec26162 zebra: Ensure master's ifname is known, even if slave comes up first
In if_netlink.c, when an interface structure, ifp, is first created,
its possible for the master to come up after the slave interface does.
This means, the slave interface has no way to display the master's ifname
in show outputs. To fix this, we need to allow creation by ifindex instead
of by ifname so that this issue is handled.

We used the vrf_id in the rtm_table field of the netlink rtmsg to fetch L3VNI.
But, now we program table_id to rtm_table field instead of vrf_id.
Thus, L3VNI fetched using rtm_table is incorrect.

Instead, use nexthop->vrf_id to fetch the L3VNI.

e15ed56cb1 zebra: Fix display of show ip import-check A.B.C.D
The 'show ip import-check A.B.C.D` code was generating
a /32 prefix for comparison.  Except import-check was
being used by bgp to track networks.  So they could
have received a /24( or anything the `network A.B.C.D/M`
statement specifies ).

Consequently when we do a `show ip import-check A.B.C.D`
we would never find the network but a `show ip import-check |
grep A.B.C.D` would find it.

Fix the exact comparison to a match.

For the `show ip nht A.B.C.D` case we are comparing
a /32 to a /32 so prefix_match will work still.
While a `show ip import-check A.B.C.D` will now show
the expected behavior as well.

6d0ee6a0d4 zebra: skip queued entries when resolving nexthop
Problem reported where certain routes were not being passed on to
clients if they were operated on while still queued for kernel
installation.   Changed it to defer working on entries that were
queued to dplane so we could operate on them after getting an
answer back from kernel installatino.
