This allows frr-reload.py (or anything else that scripts via vtysh)
to know if the vtysh command worked or hit an error.
Most of the attributes in 'struct attr_extra' allow for
the more interesting cases of using bgp. The extra
overhead of managing it will induce errors as we add
more attributes and the extra memory overhead is
negligible on anything but full bgp feeds.
Additionally this greatly simplifies the code for
the handling of data.

Restoring some code that was unintentionally removed when we were

log.c provides functionality for associating a constant (typically a
protocol constant) with a string and finding the string given the
constant. However this is highly delicate code that is extremely prone
to stack overflows and off-by-one's due to requiring the developer to
always remember to update the array size constant and to do so correctly
which, as shown by example, is never a good idea.b
The original goal of this code was to try to implement lookups in O(1)
time without a linear search through the message array. Since this code
is used 99% of the time for debugs, it's worth the 5-6 additional cmp's
worst case if it means we avoid explitable bugs due to oversights...

- All ipv4 labeled-unicast routes are now installed in the ipv4 unicast
table. This allows us to do things like take routes from an ipv4
unicast peer, allocate a label for them and TX them to a ipv4
labeled-unicast peer. We can do the opposite where we take routes from
a labeled-unicast peer, remove the label and advertise them to an ipv4
unicast peer.
- Multipath over a labeled route and non-labeled route is not allowed.
- You cannot activate a peer for both 'ipv4 unicast' and 'ipv4
labeled-unicast'
- The 'tag' variable was overloaded for zebra's route tag feature as
well as the mpls label. I added a 'mpls_label_t mpls' variable to
avoid this. This is much cleaner but resulted in touching a lot of
code.
* Ranges for some MED were 2^32 - 2 instead of 2^32 - 1
