Implement NSSA address ranges as specified by RFC 3101:
NSSA border routers may be configured with Type-7 address ranges.
Each Type-7 address range is defined as an [address,mask] pair. Many
separate Type-7 networks may fall into a single Type-7 address range,
just as a subnetted network is composed of many separate subnets.
NSSA border routers may aggregate Type-7 routes by advertising a
single Type-5 LSA for each Type-7 address range. The Type-5 LSA
resulting from a Type-7 address range match will be distributed to
all Type-5 capable areas.
Syntax:
area A.B.C.D nssa range A.B.C.D/M [<not-advertise|cost (0-16777215)>]
Example:
router ospf
router-id 1.1.1.1
area 1 nssa
area 1 nssa range 172.16.0.0/16
area 1 nssa range 10.1.0.0/16
!
Since regular area ranges and NSSA ranges have a lot in common,
this commit reuses the existing infrastructure for area ranges as
much as possible to avoid code duplication.

Description:
In PointToPoint networks, There wont be DR and BDR.
But by default, All neighbours ism state is shown as
DR_OTHER.
Changed the nbr state format to <nbrsate>/- (ex : FULL/-)
to P2pnetworks.

The calling function of ospf_nbr_nbma_lookup_next calls
this function and then immediately returns when it
gets the NULL. Just cleanup a bit more code.

ospfNbrStateChange is generated when the state of neighbor regresses or
it progresses to a terminal state. When transitioning to or from Full
state on non-broadcast multi-access and broadcast networks the trap
should be sent by the designated router. This last condition was not
taken into account when checking for the conditions of generating the
trap.

We test nbr->oi in a couple of places for null, but
in the majority of places of the nbr->oi data is being
used we just access it. Touch up code to trust this
assertion and make the code more consistent in others.

The ospf_external_route_lookup function was not
being used so let's just remove it.
Unfortunately the removal was not quite so simple as
that ospf_asbr.h was being used to generate a reference
for the `struct ospf_route` data structure, so we
need to fix up the compile by fixing up header
inclusions so that ospf_route.h is actually included

The following types are nonstandard:
- u_char
- u_short
- u_int
- u_long
- u_int8_t
- u_int16_t
- u_int32_t
Replace them with the C99 standard types:
- uint8_t
- unsigned short
- unsigned int
- unsigned long
- uint8_t
- uint16_t
- uint32_t

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...

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

A few places are using 0 in place of the MTYPE_* argument. The
following rewrite of the alloc tracking won't deal with that, so let's
use MTYPE_TMP instead.

Quagga sources have inherited a slew of Page Feed (^L, \xC) characters
from ancient history. Among other things, these break patchwork's
XML-RPC API because \xC is not a valid character in XML documents.
Nuke them from high orbit.
Patches can be adapted simply by:
sed -e 's%^L%%' -i filename.patch
(you can type page feeds in some environments with Ctrl-V Ctrl-L)

Most table handlers do not expect to be given an OID whose prefix is
outside what they can handle. This is not a problem with the SMUX
implementation since it always correct the OID such that the prefix
matches. However, this is not the case for the AgentX
implementation. A new function, smux_header_table() is used to do this
normalization.
smux_trap() signature has been changed to provide appropriate level
information to send SNMPv2 notifications. This includes the addition
of the enterprise OID to use (from which is derived the SNMP trap OID)
and the MIB registry to locate the appropriate function for variable
bindings provided by the trap.
The SMUX implementation has been updated but ignore the provided
enterprise OID. Instead, it still uses the SMUX peer OID to keep
compatibility with previous versions of Quagga. The SMUX
implementation also ignores the provided MIB registry since it uses
smux_get() function to grab the appropriate values. This is not
possible with the AgentX implementation since there is no such
function provided by NetSNMP.
smux_trap() contains an argument whose use appears to be to set
sysUpTime.0/timestamp field in SNMP trap. However, this value is not
used in smux_trap(). Moreover, it is expected that this field is the
value of sysUpTime.0 when the trap was sent and not any other time
related to the trap. To avoid any confusion, we remove this field from
the signature of the function.
