[FROG] Why two duplicate route-map exist in bgpd and zebra ?

Including multiple security fixes.

To expound on Donald's routemap comment a bit - you're probably seeing this
because you're using separate config files for each daemon. If you use
quagga.conf (or frr.conf) and apply that with vtysh, vtysh will handle
distributing daemon specific config to just the daemons that understand it.
