BGP and relevant configuration for this address family.

Internal and IANA definitions for labeled-unicast SAFI. Note that this SAFI
is specific to BGP and maps to the corresponding unicast SAFI in Zebra.

Support install of labeled-unicast routes by a client. This would be
BGP, in order to install routes corresponding to AFI/SAFI 1/4 (IPv4)
or 2/4 (IPv6). Convert labeled-unicast routes into label forwarding
entries (i.e., transit LSPs) when there is a static label binding.

Implement interface that allows a client to register a FEC for obtaining
a label binding (in-label). Update client whenever the label binding is
updated and cleanup when client goes away.

Implement static label binding of a label to a prefix (FEC).
Note: Currently, only binding to a prefix is supported, the nexthop and/or
other parameters are not considered. This was cherry-picked by hand from
an earlier mpls branch.

Use the eigrp_topology_successors to give us the
list of successors we want to install.
Modify route add to send all the nexthops
Modify route delete to just delete the route

Each call into eigrp_topology_get_successors would leak the list
created. As routes worked their way through the FSM we would
leak memory left and right.
Modify the eigrp_topology_get_successor to return NULL when
there are no SUCCESORS.
Clean up some dead code.

When we have a *,G mroute that starts receiving any particular
S,G, we will get wholepkt callbacks due to the pimreg in the
OIL for the *,G.
So we need to do SPT switchover, but this can fail if we
do not have a path to the S( but we do to the RP!).
In this case fail gracefully.

This allows SPT switchover for S,G upon receipt of packets
on the LHR.
1) When we create a *,G from a IGMP Group Report, install
the *,G route with the pimreg device on the OIL.
2) When a packet hits the LHR that matches the *,G, we will
get a WHOLEPKT callback from the kernel and if we cannot
find the S,G, that means we have matched it on the LHR via
the *,G mroute. Create the S,G start the KAT and run
inherited_olist.
3) When the S,G times out, safely remove the S,G via
the KAT expiry
4) When the *,G is removed, remove any S,G associated
with it via the LHR flag.

The snmp code is being included in the build of the vtysh_cmd.c
irrelevant of whether or not it is needed. Be a bit smarter
about what files to include.

The SNMP modules include <net-snmp/net-snmp-config.h>, which won't be
found in off-searchpath directories without SNMP_CFLAGS. Unfortunately
in my tests the files were on the search path even without the flags.
(SNMP_LIBS is not needed because only libfrrsnmp calls into net-snmp
functions.)
