Looking for a bgp listener that works with RADIX_MPATH / EQMP that's in HEAD

[Scott Long]

We run bird for this task.  Can't say if it works on 10 since he haven't
moved to 10 yet, but there have been some experiments with running
a 10 kernel in the 9 userland and bird seems to behave fine with that.
