bgpd: resolve ipv6 ecmp issue with vrfs and ll nexthop
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.

bgpd: More Extended nexthop fixing
Basically if we are reading in a cli with a extended-nexthop
and we have not received from zebra the interface we are working
on I believe we have a race condition where we are not
propagating the PEER_FLAG_CAPABILITY_ENHE in this case.
Modify the code to propagate even if we haven't found the
interface yet.

bgpd: Fix occassional turn off of extended-nexthop for an if
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.

Revert "Fix the "Use-after-free" of clang SA."
- This's the wrong way to fix this problem.
- Since the "TAILQ_FIRST()" always return diferent pointer as we call "TAILQ_REMOVE()", the clang static analyzer can't detect this behavior.
- Ignore this warning and keep files identical to its original one.
redhat: use %initsystem check that works when chrooted
`systemctl' returns different, non-useful output while in a chroot.
Switch to checking if /sbin/init is a symlink to the systemd binary.
With this change the build works in a mock chroot.
