ospfd: trap on state change seems to send incorrect value for ospfNbrState
The ospfNbrState in the ospf trap sent from ospfd shows an incorrect state.
For example, when the connection goes down, the ospfNbrState in the trap is
sent as '8' (full). When the connection is reestablished, the state is sent
as '7' (loading).
The reason seems to be that the trap is sent from nsm_notice_state_change()
before the state is actually updated by calling nsm_change_state().
After applying the attached patch, the traps are sent with nbrState '1' when
the connection goes down and '8' when it goes back up.

isis_pdu.c :
New adjacency did not always get added to LSP neighbor list.
The adjacencies that were created once minimum time allowed before LSP
retransmission had surpassed, instantly got their LSP regenerated, but
the adjacency circuit type was not set to IIH PDU circuit type before
the LSP was regenerated , hence didn't pass the check for adjacency
circuit type in lsp_build(), and the adjacency was not added to neighbor list.
When a new adjacency is up, to build LSP with neighbor entry corresponding
to the adjacency, set adjacency circuit type to circuit type from hello PDU
header before new LSP is regenerated/built. This will result in the new
adjacency entry getting added to the LSP neighbor list TLV.

pimd: Create special pimreg interface
The linux kernel wants a pimreg vif device. The pimd
code wants a 'struct interface *' for anything it works
with. Since the pimreg vif device is not a real linux
device that zebra knows about. Cheat by creating
a pimreg interface pointer and setup the code to
properly be able to handle the registration of the vif
device.

pimd: Add New Source type for where a (S,G) mroute is learned
Add Source type for (S,G) mroute. This will allow us to know that
a (S,G) route came from an actual Source( ie the kernel called us
back with information about a multicast packet it received with
no mroute for it ).
