Default not to print the service name as we discussed during the NFWS.
# nft list ruleset
table ip x {
chain y {
tcp dport 22
ip saddr 1.1.1.1
}
}
# nft -l list ruleset
table ip x {
chain y {
tcp dport ssh
ip saddr 1.1.1.1
}
}
# nft -ll list ruleset
table ip x {
chain y {
tcp dport 22
ip saddr 1dot1dot1dot1.cloudflare-dns.com
}
}
Then, -ll displays FQDN. just like the (now deprecated) --ip2name (-N)
option.

With libnftables documentation being upstream and one confirmed external
user (nftlb), time to break the API!
First of all, the command buffer passed to nft_run_cmd_from_buffer may
(and should) be const. One should consider it a bug if that function
ever changed it's content.
On the other hand, there is no point in passing the buffer's length as
separate argument: NULL bytes are not expected to occur in the input, so
it is safe to rely upon strlen(). Also, the actual parsers don't require
a buffer length passed to them, either. The only use-case for it is when
reallocating the buffer to append a final newline character, there
strlen() is perfectly sufficient.

Although technically there already is support for JSON output via 'nft
export json' command, it is hardly useable since it exports all the gory
details of nftables VM. Also, libnftables has no control over what is
exported since the content comes directly from libnftnl.
Instead, implement JSON format support for regular 'nft list' commands.

Instruct Make to actually install the header to the system, otherwise
users won't see the header in their system after running 'make install'.
Also, export main libnftables header with a proper name, since we have another
private header called 'nftables.h' (i.e, let's be concrete with the naming).
