KevinLiang10	a3c7b21cd1	util/linuxfw: add nftables support ... This commit adds nftable rule injection for tailscaled. If tailscaled is started with envknob TS_DEBUG_USE_NETLINK_NFTABLES = true, the router will use nftables to manage firewall rules.

Andrew Dunham	ba48ec5e39	util/linuxfw: initial implementation of package ... This package is an initial implementation of something that can read netfilter and iptables rules from the Linux kernel without needing to shell out to an external utility; it speaks directly to the kernel using syscalls and parses the data returned. Currently this is read-only since it only knows how to parse a subset of the available data.
