Jason A. Donenfeld 1d4eb2727a netstack: introduce new module for gvisor tcp tun adapter
The Go linker isn't smart enough to prevent gvisor from being pulled
into modules that use other parts of tun/, due to the types exposed. So,
we put this into its own standalone module.

We use this as an opportunity to introduce some example code as well.

I'm still not happy that this not only clutters this repo's go.sum, but
all the other projects that consume it, but it seems like making a new
module inside of this repo will lead to even greater confusion.
