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.

The `-i` option on sed isn't standard, and e.g. FreeBSD sed behaves
different regarding the parameter. Avoid it.

libtool does not understand `-coverage` with a single dash. Official
gcc docs also say `--coverage` rather than `-coverage`. (clang lists
both.)
Also, for correct linking, libtool needs `--coverage` in LDFLAGS as
opposed to `-lgcov` (with the latter you get library ordering/deps
issues)

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: 0c4285d77e ("build: properly split CFLAGS from AC_CFLAGS")

RFC 3623 specifies the Graceful Restart enhancement to the OSPF
routing protocol. This PR implements support for the restarting mode,
whereas the helper mode was implemented by #6811.
This work is based on #6782, which implemented the pre-restart part
and settled the foundations for the post-restart part (behavioral
changes, GR exit conditions, and on-exit actions).
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 ospf`
EXEC-level command needs to be issued before restarting the ospfd
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 ospfd 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.

...really no reason to force this into a compile time decision. The
only point is avoiding the getrusage() syscall, which can easily be a
runtime decision.

This adds _clippy.ELFFile, which provides a fast wrapper around libelf.
The API is similar to / a subset of pyelfutils, which unfortunately is
painfully slow (to the tune of minutes instead of seconds.)
The idea is that xrefs can be read out of ELF files by reading out the
"xref_array" section or "FRRouting/XREF" note.

This adds the machinery for cross reference points (hence "xref") for
things to be annotated with source code location or other metadata
and/or to be uniquely identified and found at runtime or by dissecting
executable files.
The extraction tool to walk down an ELF file is done and working but
needs some more cleanup and will be added in a separate commit.
