To announce connected prefixes, or not to announce connected prefixes,

This command makes unplanned GR more reliable by manipulating the
sending of Grace-LSAs and Hello packets for a certain amount of time,
increasing the chance that the neighboring routers are aware of
the ongoing graceful restart before resuming normal OSPF operation.

Rather than running selected source files through the preprocessor and a
bunch of perl regex'ing to get the list of all DEFUNs, use the data
collected in frr.xref.
This not only eliminates issues we've been having with preprocessor
failures due to nonexistent header files, but is also much faster.
Where extract.pl would take 5s, this now finishes in 0.2s. And since
this is a non-parallelizable build step towards the end of the build
(dependent on a lot of other things being done already), the speedup is
actually noticeable.
Also files containing CLI no longer need to be listed in `vtysh_scan`
since the .xref data covers everything. `#ifndef VTYSH_EXTRACT_PL`
checks are equally obsolete.

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 X:X::X:X/M [<not-advertise|cost (0-16777215)>]
Example:
router ospf6
ospf6 router-id 1.1.1.1
area 1 nssa
area 1 nssa range 2001:db8:1000::/64
area 1 nssa range 2001:db8:2000::/64

RFC 5187 specifies the Graceful Restart enhancement to the OSPFv3
routing protocol. This commit implements support for the GR
restarting mode.
Here's a quick summary of how the GR restarting mode works:
* GR can be enabled on a per-instance basis using the `graceful-restart
[grace-period (1-1800)]` command;
* To perform a graceful shutdown, the `graceful-restart prepare ipv6
ospf` EXEC-level command needs to be issued before restarting the
ospf6d daemon (there's no specific requirement on how the daemon
should be restarted);
* `graceful-restart prepare ospf` will initiate the graceful restart
for all GR-enabled instances by taking the following actions:
o Flooding Grace-LSAs over all interfaces
o Freezing the OSPF routes in the RIB
o Saving the end of the grace period in non-volatile memory (a JSON
file stored in `$frr_statedir`)
* Once ospf6d is started again, it will follow the procedures
described in RFC 3623 until it detects it's time to exit the graceful
restart (either successfully or unsuccessfully).
Testing done:
* New topotest featuring a multi-area OSPF topology (including stub
and NSSA areas);
* Successful interop tests against IOS-XR routers acting as helpers.

Ospfv3 ASBR summarisation feature
|
|
like the other automake variables, setting `xyz_LDFLAGS` causes
`AM_LDFLAGS` to be ignored for `xyz`. For some reason I had in my mind
that automake doesn't do this for LDFLAGS, but... it does. (Which is
consistent with `_CFLAGS` and co.)
So, all the libraries and modules have been ignoring `AM_LDFLAGS` (which
includes `SAN_FLAGS` too). Set up new `LIB_LDFLAGS` and
`MODULE_LDFLAGS` to handle all of this correctly (and move these bits to
a central location.)
Fixes: #9034
Fixes: 0c4285d77eb ("build: properly split CFLAGS from AC_CFLAGS")

Feature Implementation.
========================
This feature will help in advertising the External LSAs with aggregation.
The commands allow us to tune the advertisement with different parameters
as mentioned in the CLI List below.
It can also help in case we do not want to advertise any prefix with the
no-advertise option.
New CLIs added:
===============
summary-address X:X::X:X/M$prefix [tag (1-4294967295)] [{metric (0-16777215) | metric-type (1-2)}]
no summary-address X:X::X:X/M$prefix [tag (1-4294967295)] [{metric (0-16777215) | metric-type (1-2)}]
summary-address X:X::X:X/M$prefix no-advertise
no summary-address X:X::X:X/M$prefix no-advertise
aggregation timer (5-1800)
no aggregation timer (5-1800)
show ipv6 ospf6 summary-address [detail$detail] [json]
debug ospf6 lsa aggregation

Adding the "clear ipv6 ospf6 command" . It resets
the ospfv3 datastructures and clears the database
as well as route tables. It resets the neighborship
by restarting the interface state machine.
If the user wants to change the router-id, this
command updates the router-id to the latest static
router-id and starts the neighbor formation with
the new router-id.

Most of these are many, many years out of date. All of them vary
randomly in quality. They show up by default in packages where they
aren't really useful now that we use integrated config. Remove them.
The useful ones have been moved to the docs.

Programs that link to libnetsnmp must be compiled using a special set
of flags as specified by the "net-snmp-config --base-cflags" command
(whose output is stored in the SNMP_CFLAGS variable). The problem is
that "net-snmp-config --base-cflags" can output -std=c99 in addition to
other compiler flags in some platforms, and this breaks the build since
FRR souce code makes use of some GNU compiler extensions (e.g. allow
trailing commas in function parameter lists). In order to solve this
problem, append -std=gnu99 after SNMP_CFLAGS in all makefiles where this
variable is used. This way the -std=c99 flag will be overwritten when it's
present. Source files that don't link to libnetsnmp will be compiled using
either -std=gnu99 or -std=gnu11 depending on the compiler availability.
Fixes #1617.
