That package was long out of date, but being held back by govendor
because it's pre-vendoring "external" folder was listed in vendor.json
but has since been removed from the repo.
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.
* Remove `make updatedeps` from Travis build. We'll follow up with more
specific plans around dependency updating in subsequent PRs.
* Update all `make` targets to set `GO15VENDOREXPERIMENT=1` and to
filter out `/vendor/` from `./...` where appropriate.
* Temporarily remove `vet` from the `make test` target until we can
figure out how to get it to not vet `vendor/`. (Initial
experimentation failed to yield the proper incantation.)
Everything is pinned to current master, with the exception of:
* Azure/azure-sdk-for-go which is pinned before the breaking change today
* aws/aws-sdk-go which is pinned to the most recent tag
The documentation still needs to be updated, which we can do in a follow
up PR. The goal here is to unblock release.
