The changes introduced in PR #1044 caused pim to notice
when a setsockopt call failed. The kicker here is that
this used to just work because we ignored the issue
pre. So VRF's need to BINDTODEVICE to get igmp callbacks
but the default vrf does not need to do so.
With the fix we now see IGMP group join:
root@dell-s6000-02 ~/frr# vtysh -c "show ip igmp group"

With the change to make zebra pass routes to the kernel
with the 'correct' proto name, it caused zebra to
not properly recognize them on startup again
the next time such that the route would not
be deleted.
Modify rt_netlink.c to notice that we have a
self originated route and to properly mark
the type of route it was.
Modify rib_table_sweep to mark the nexthops
as active so that when we go to delete the
self originated routes it would properly
delete from the kernel.

1) Add hash names to all hash_create calls
2) Fix community_hash, ecommunity_hash and lcommunity_hash key
creation
3) Fix output of community and lcommunity iterators( why would
we want to see the memory location of the backet? ).

1) Some hash key functions where converting pointers
directly to a 32 bit value via downcasting. Pointers
are 64 bit on a majority of our platforms.
2) Some hashes were being created with 256 entries,
downsize the hash creation size to more appropriate
values.
3) Add hash names to hash creation so we can watch
the hash via 'show debugging hashtable'

RIP is testing to ensure that the metric returned
isn't negative. We should be looking at the returned
value from the cli strtol.
If we get a metric value that is less than zero that
means that we shouldn't use this value in RIP currently.
So signify that by returning mod here.

I missed this in review; the old vtysh command should have been removed
when adding the new one.

If we configure a static route pointing to null0 and zebra displays
it with the 'blackhole' keyword in the running configuration, the
frr-reload.py script will have issues. Fix this by introducing the
'static_blackhole_type' enum.
Fixes#1091.

Link-local routes are unique in the sense that they all have the same
prefix but have different nexthops (local interfaces). Add an exception
in rib_add() to allows us to keep track of all of them.

NOTE: the check for ROUTE_ENTRY_REMOVED was redundant as it was already
performed at the beginning of the loop.

This reference counter was introduced in 2001, apparently to solve a
problem with connected routes being added/removed multiple times. The RIB
code changed a lot since then, and giving the current callers of rib_add()
and rib_delete() it's safe to assume that we don't need this anymore.
