Motivation: There is a thriving plugin ecosystem for Kakoune now,
and it is nice to add these in our Nix configurations. This was modeled
on neovim's plugins.
parinfer-rust is useable both standalone and as a Kakoune plugin,
so the plugin file inherits the same definition as pkgs.
I'll make PRs for other plugins if this gets accepted.
[Here](https://github.com/eraserhd/nixpkgs/tree/kak-ansi)'s a tested
branch for the `kak-ansi` plugin.
Also move to a pkgs/os-specific/linux/kernel/linux-mptcp-94.nix. makes
updates easier.
Added a structured config pkgs/os-specific/linux/kernel/mptcp-config.nix
that can be shared between the different kernels.
The team behind ksonnet was aquired by VMware, and they decided to end
work on ksonnet:
