It will be mostly implemented with ucode templates installed at
/usr/share/ss-rules and called from init script. The generated nftables
rules will be stored at /etc/nftables.d/
Incompatible changes were introduced as described in the README.md file
- Netfilter ipset was replaced with nftables sets
- UCI options ipt_args and dst_forward_recentrst of section ss_rules
are now deprecated. The former does not apply to nftables. The
later not yet implemented with nftables.

ss-rules with iptables needs presence of netfilter nat table to work.
ss-rules works before without explicitly requesting it as a dependency
because it's present by default on a pre-firewall4/nftables OpenWrt
install. We request it explicitly now to make life easier in case
people would like to try ss-rules/iptables on firewall4/nftables enabled
OpenWrt system

At the moment ss-server seems to be the only component using these two
options. It also accepts "local_address" of either ip4 or ip6 address,
but the meaning is different from that of ss-local, ss-tunnel etc.
where it is for listen bind
With this commit, we start deprecation process of uci option
"bind_address". The name was replaced with "local_addr" in upstream
project commit 5fa98a66 ("Fix #1911") and available as json config
option "local_address". This upstream change was released in 3.2.0

Linux kernel and iproute2 together now implement strict checking of the
existence of route tables.
Previously kernel does not support filtering by table id, now it does
and will error with nlmsgerr "ipv4: FIB table does not exist".
Previously iproute2 dump all routes and filter by table id in userspace,
now this has changed with iproute2 commit c7e6371bc4af ("ip route: Add
protocol, table id and device to dump request")
Error scene
root@OpenWrt:/# ip route flush table 100
Error: ipv4: FIB table does not exist.
Flush terminated

Plugin options are properties of shadowsocks deployment as a whole,
including both server and each client components. Multiple client
instances accessing the same server will need to share the same plugin
settings
With this change, plugin options will need to specified to "server" and
"ss-server" section, not to each component section.
