*: Initial Import of Babeld into FRR

This is a direct copy of:
https://github.com/boutier/quagga-merge

From the branch babel-merge

I copied the babeld directory into FRR and then fixed up everything to
compile.

Babeld at this point in time when run will more than likely crash and burn
in it's interfactions with zebra.

I might have messed up the cli, which will need to be looked at

extract.pl.in and vtysh.c need to be fixed up.  Additionally we probably
need to work on DEFUN_NOSH conversion in babeld as well
