This change makes the zebra acting as label manager proxy not to relay non-LM
messages to clients that a zebra acting in non-proxy mode may send to it. Also,
the existing code does not schedule a rcv in case of relay_response_back
returns -1. This patch re-schedules reads on the socket even in case such a
function returns -1 by calling thread_add_read().

Corrections so that the BGP daemon can work with the label manager properly
through a label-manager proxy. Details:
- Correction so the BGP daemon behind a proxy label manager gets the range
correctly (-I added to the BGP daemon, to set the daemon instance id)
- For the BGP case, added an asynchronous label manager connect command so
the labels get recycled in case of a BGP daemon reconnection. With this,
BGPd and LDPd would behave similarly.

Netdevices are not sorted in any fashion by the kernel during the initial
interface nldump. So you can get an upper device (such as an SVI) before
its corresponding lower device (bridge).
To fix this problem we skip resolving link dependencies during handling of
nldump notifications. Resolving instead at the end (when all the devices
are present)

So the linux kernel uses the RT_TABLE_MAIN for the table
id used for ip routing. The multicast routing tables use
RT_TABLE_DEFAULT. We changed the internal code of zebra_vrf
a few months back to use RT_TABLE_MAIN as the tableid to
use. This caused the pim sg stats to stop working because
of the kernel bug where it uses a different table
for ip routing and ip multicast.
Put a bit of a special case in to do the right thing.

place to do this is in the pim socket in pimd.
