When a non-default vrf rd is configured under l2vpn evpn in a vrf,
we need to update the config file.

The TODO file had become a dumping ground of changes made
to the protocol. That when we modified the underlying code
we would need to update the TODO file again due to it's nature.
There is no point in keeping the list of items that we've done
as that commit messages will indicate the new features. So
pull out all the Finished work and rework the Todo numbers
used.

The ZEBRA_FLAG_INTERNAL flag is used to signal to zebra that
the route being added, the nexthops for it can be recursively
resolved. This name keeps throwing me off when I read it
so let's rename to something that allows the developer to
understand what is going on.

peer->ifindex was only used in two places but it was never populated so
neither of them worked as they should. 'struct peer' also has a 'struct
interface' pointer which we can use to get the ifindex.
In the future we are going to have a rule_notify_owner
so make the distinction between the two types of notification
clearer.

The 'struct route_entry *old' and 'struct route_entry *new' can sometimes
be the same route type( for a route replace ), so when we are checking
to see if a new owner has taken over, don't tell the owner it is
replacing it self.

The notification of the owner was not properly decoding
the prefix and as such we were not properly reading the
table it was installed into.

Update the centos7 build instructions to include
data on how to build w/ systemd. This is especially
useful because we tell the user to install the frr.service
file and the frr.service file expects systemd integration

Because checkpatch result is applied to original and new file, the
analysis also parses what may be wrong with the original file.
Whereas the script should limit to analyse only what is wrong on new
file.

Some of the tables are no longer stored in the zvrf
and in the zns now. On shutdown zns is cleaned up
after vrf( and rightly so!) As such we should not
attempt to count the information if we don't have
a zvrf.

The linux kernel allows a vast expanse of tables to be used.
It would be useful for zebra to track these tables if they
are being used.

The other_tables data structure does not belong to a vrf.
It belongs to the zns. This is because each vrf does not
need to have copies of each of other_tables.
Additionally move the array into a RB_TREE. This will allow
us to sort quickly and easily expand the number of tables
we can support to beyond the ZEBRA_KERNEL_TABLE_MAX define.

A Border Leaf can originate a default route
for all the leafs within the POD.
However, we do not want to advertise this route outside the POD.
Therefore, we provide an option
to filter a EVPN type5 default route through a route-map.

Implement support for 'default-originate' for L2VPN/EVPN address family.
This is needed for the case where external routing within a POD,
will follow the default route to the border/exit leaf.
The border leaf has more than one next hop to forward the packet on to,
depending on the destination IP.

Type-5 routes can be useful in multiple scenarios such as advertise-subnet,
default-originate etc. Currently, the code has a restriction that to allow
advertising type-5 routes, user has to first enable advertise ipvX command.
This restriction is not necessary and should be removed.

BSD systems need gmake to build FRR, hence why we use $(MAKE) instead of
directly invoking make. It looks like Sphinx generated makefiles
understand this, but contain a bug where the target for info files
hardcodes make instead of using $(MAKE). Fix this.

Problem seen when a prefix was learned with nexthops from multiple
route sources (static and ospf in this case) and the link to that
nexthop flaps. The nht entry was incorrectly deleted so when the
link came back up the static was not re-installed correctly.

Incorrect check for sentinel value effectively caused peers to sometimes

Some platforms (actually just Centos6, again, of course) call
"sphinx-build" as "sphinx-1.0-build", and so to work around this
apparently useless name, fall back to sphinx-1.0-build when we can't
find sphinx-build before displaying an error message. I am not doing in
this the configure script because the sphinx makefiles are not Automake
files and the less Automake in tree the better.
