Problem reported by customer that ipv6 wasn't installing ecmp paths
when using vrfs. Found a vrf-unware call in bgp_zebra_announce that
was the culprit. Testing of the fix looks good.

Before the change, a reload triggered a restart if the python reload script wasn't installed or for non-integrated configs
With this change, the reload is rejected with an error in this case (and suggests the installation of the python script package)

Problem reported was that with some overlapping static route configurations,
when the link went down the less specific static was not re-installed after
the link came back up. Determined that with the overlapping statics, we
would recursively resolve the next-hop temporarily thru the more specific
static route, but since the next-hop wasn't actually reachable, we would go
through the code that clears the nht information for the static completely.
This caused the nht code to no longer process the static route.
After reviewing the process, there doesn't seem to be any reason that the
static should be deregistered in that section of code. Removed the
deregister and the problem is resolved and not addional failures seen in
manual testing. zebra_test.py completed successfully and ospf and bgp smokes
completed with no new failures.

Encountered a crash in zebra due to getting a delete on an SVI with
VRR configured. Since we don't actually do a delete but flag the interface
as inactive, slag VRR interfaces would remain on the vrf_iflist with a lock
count of zero, causing the crash. Since all other interface types are moved
to the default table before deleting, doing the same thing for any interfaces
that were left in the vrf.
Testing includes manual testing, bgp-min, ospf-min, vrf-min, bgp-smoke, and ospf-smoke.
All passed (first time or on rerun) or match known failures.

When an entire address-family section is removed from under BGP, we
cannot just issue 'no address-family foo bar' as address-family line
doesn't support 'no'. We have to delete the individual lines under the

Problem reported that ecmp wasn't working correctly in a vrf with
ipv6. Issue was that originator of the routes were sending the updates
with a link-local nexthop and nhlen of 16. In this particular case,
bgp_zebra_announce was using the wrong call to get the ifindex and
was not supplying the vrf. This caused ecmp to work only in the case
of the default vrf.

Basically if we are reading in a cli with a extended-nexthop

on I believe we have a race condition where we are not
propagating the PEER_FLAG_CAPABILITY_ENHE in this case.

Sometimes, like once every 400 iterations, when you restart
Quagga, extended-nexthop has been turned off for interface
based config( for 5549 ).
Examining the code, there is only 1 real path to setting
the PEER_FLAG_CAPABILITITY_ENHE and that is through
peer_conf_interface_get. Modify this code path
to always set the PEER_FLAG_CAPABILITY_ENHE if it is
not already set.
In addition, fix a possible pointer dereference.
