MPLS enable quagga
------------------

This patch adds a MPLS framework to the quagga routing suite.  The bulk of the
changes are to the 'zebra' daemon, which now allows for statically configuring
LSPs and binding routes to them.

Run it
------

After compiling and installing the MPLS modified version of quagga, you will
have a new CLI commands for the 'zebra' daemon.

Here is a simple example of how to use these new commands to configure a
static LSP and bind a route to it:

    Ingress LER
    ----------- 
    iler# conf t
    iler(config)# ip route 10.0.0.0/24 gen 16 nexthop eth1 192.168.2.1
    iler(config)# end
    iler# show mpls forwarding
    Insegments:

    Outsegments:
      Interface          Label Next Hop        Owner
      eth1                  16 192.168.2.1     STATIC

    iler# show ip route 10.0.0.0/24
    Routing entry for 10.0.0.0/24
      Known via "static", distance 1, metric 0, best
      * 192.168.2.1, via eth1 (label 16)
