nft-sync development has been stalled for two years. Since then the
libnftnl API has changed, breaking the build.
Apply the required changes to make the project build again.

This fixes a use-after-free since the set object is added into the set
list.

This patch complete the --fetch operation in the server side.
By now, the format of the ruleset is XML. In further patches we can include
additional config options to let the admin choose one of XML/JSON.

This patch bootstrap the new nft-sync software. Basically, this
software aims to support two different setups:
1) Rule-set repository server. The software serves the nft rule-set to
clients that request the ruleset.
Basically from the system that acts as repository, you have to run:
# nft-sync -c ../contrib/nft-sync.conf.server
Then, from the client:
# nft-sync -c ../contrib/nft-sync.conf.client --fetch
Which displays the nft rule-set in the standard output, so you
can inspect the nft rule-set.
Alternatively, the client can also retrieve and apply the nft
rule-set using the pull command instead:
# nft-sync -c ../contrib/nft-sync.conf.client --pull
[ Note that this command above does not work in this bootstrap yet ]
2) Rule-set synchronization: In case of primary-backup and multiprimary
firewall configurations, the software makes sure that the firewall
cluster is deploying the same filtering policy. In this case, you have
to launch the process:
# nft-sync -c ../contrib/nft-sync.conf --sync
[ Note that this command above does not work in this bootstrap yet ]
This bootstrap provides the basic infrastructure as a proof-of-concept.
Many of the necessary features are still lacking:
* Implement --sync and --pull commands.
* Interaction with nft through libnftnl, which allows the software to
retrieve the local nft rule-set, as well as to parse it and apply it.
* SSL support, specifically the repository mode needs it to make sure
nobody can steal your filtering policy from the network.
* IPv6 support.
* Allow to serve different rule-sets in the repository mode.
And many others that will be added progressively.
