We've missed a few recent additions to go.mod in the vendor directory. We
need to keep this updated for the moment until all of the surrounding
tooling is ready to go all-in with Go 1.11 modules.
This work was done against APIs that were already changed in the branch
before work began, and so it doesn't apply to the v0.12 development work.
To allow v0.12 to merge down to master, we'll revert this work out for now
and then re-introduce equivalent functionality in later commits that works
against the new APIs.
The original contents of `vendor` were inadvertently captured with an
older version of `godep`. Here, we recapture dependencies by running the
following:
```
godep restore -v
cat Godeps/Godeps.json | jq -r '.Deps[].ImportPath' | xargs godep update -v
```
The newer godep makes the following changes as it captures dependencies:
* Skips test files
* Copies `LICENSE` / `PATENTS` files
There is also an additional diff in `golang.org/x/sys/unix` that looks
very similar to the diff between `master..c65f27f` in that repo, so I'm
guessing that dependency was accidentally captured from master instead
of the commit saved to `Godeps.json`.
All in all, these changes should all be "more correct" and result in
smaller diffs for any future updates made to dependencies.
