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
* Use correct printf specifiers for unsigned values
* Some drive-by CLI collapsing and simplification

Sometimes, like once every 400 iterations, when you restart
Quagga, extended-nexthop has been turned off for interface
based config( for 5549 ).
Examining the code, there is only 1 real path to setting
the PEER_FLAG_CAPABILITITY_ENHE and that is through
peer_conf_interface_get. Modify this code path
to always set the PEER_FLAG_CAPABILITY_ENHE if it is
not already set.
In addition, fix a possible pointer dereference.

1) When we enter a 'neighbor shutdown..' command for a peer

The use of VTY_DECLVAR_CONTEXT(bgp, bgp) here is wrong as we are not
inside the "router bgp" configuration node. This was making the clear
commands always fail with a "Current configuration object was deleted
by another process" error, which doesn't make any sense.
Also, the bgp_clear() function will already check for us if the given
peer-group or neighbor exists or not, there's no need to duplicate this
logic here.

The JSON output of 'bgp neighbor show' lacked the decoded strings for
the last notification error code/subcode. Decoding these strings outside
quagga is painful, and then needs to match with any updates to the codes
from RFCs/drafts. Further, all apps that look to understanding this need
to then add their own decoders for these strings.
Just add the decoded strings to the JSON output as well. JSON key name
for this is 'lastNotificationReason'.
