That's doable, but linenoise code does not use the static global cli_nft
variable and thus cli_exit() can't access the struct nft_ctx pointer.

At first, I tried to make main() not exit after calling cli_init() so
final cleanup takes place. But the different CLI variants are a bit of a
mess in that regard: While there are code-paths returning to caller,
most don't. I'm tempted to fix that instead. What do you think?

Thanks, Phil
