New compilers are noticing that the tests are compiling with
a pointer for the bgpd_privs variable while the bgp library
that is being linked against is not a pointer. Since
these tests had the declaration just to make the compiler
happy, let's actually align the variable type to make the
compiler even happier.

The compiler is, rightly, pointing out that in some cases it is
possible that the pkt_afi and pkt_safi values are not properly
set and could result in a use before initialized. I do not
actually belive that this is possible, but let's make the compiler
happy.

The logic to unlock dest if iteration completed without iterating the
entire node was flawed. Specifically, if iteration terminated due to
`gr_deferred == 0` then the node would not get unlocked.
This change takes into account the fact that dest will be NULL only in
the case when the entire table was iterated and all nodes were already
unlocked. In any other case, it needs to be unlocked.

By changing this API call to use a `struct ipaddr`, which encodes the
type of IP address with it. (And rename/remove the `IPV4` from the
command name.)
Also add a comment explaining that this function call is going to be
obsolete in the long run since pimd needs to move to proper MRIB NHT.

The normal flag was enabling detail messages, but what we want is the
detail flag enabling normal messages.
Remove the _ONLY macro while at it, it's only used for config print &
that seems like a place where making the difference explicitly visible
is helpful regardless.

If duplicate value is entered, the whole plist/alist just dropped.
Before:
```
$ grep prefix-list /etc/frr/frr.conf
ip prefix-list test seq 5 permit 1.1.1.1/32
ip prefix-list test seq 10 permit 1.1.1.1/32
$ systemctl restart frr
$ vtysh -c 'show run | include prefix-list'
$
```
After:
```
$ grep prefix-list /etc/frr/frr.conf
ip prefix-list test seq 5 permit 1.1.1.1/32
ip prefix-list test seq 10 permit 1.1.1.1/32
$ systemctl restart frr
$ vtysh -c 'show run | include prefix-list'
ip prefix-list test seq 5 permit 1.1.1.1/32

Some recent improvement in GCC triggers 2 new warnings, and they're
actual bugs (reading beyond end of prefix_ipv6 by accessing it as
prefix, which is larger.) Luckily it's only in sharpd.

Prior to this fix, the magic number (16) was used regardless of what value
the user specified for func-bits. With this fix, user-specified values are
handled appropriately.

RT value will be unique across different VNIs but the
same across routers (in the same AS) for a particula

It is unique, so add `break` for search procedure.

Fix: 06e4e90132
Modified BGP to pay more attention the prefix returned from
zebra to ensure that a LPM wasn't accidently causing BGP
import checks to think it had a match when it did not.
This unfortunately removed the check to handle the route
removal.
This sequence of config and events would leave BGP in a bad state:
ip route 100.100.100.0/24 Null0
router bgp 32932
bgp network import-check
address-family ipv4 uni
network 100.100.100.0/24
Then if you removed the static route the import check would
still think the route existed:
donatas-pc(config)# ip route 100.100.100.0/24 Null0
donatas-pc(config)# do sh ip bgp import-check-table
Current BGP import check cache:
100.100.100.0 valid [IGP metric 0], #paths 1
blackhole

Fix this by moving the code to handle the prefix check to the
evaluation function and mark the bnc as not matching and actually
evaluate the bnc.

Other VRFs get VRF_ADD notifications from zebra which triggers
static_fixup_vrf_ids, but since the default VRF is implicit we need to
make that same call on connect.
This should fix problems with staticd being started before (or
concurrent with and thus racing) zebra.

nh_update is only called in two places and both precede a matching
follow-up nht_register call. Fold the update into register, and make
register do the right thing™ for all cases (i.e. update refcounts as
needed, and retry zebra NHT registration if it failed before).
