WIP: vendor: Update with a fresh vndr run

[wking]

Generated by running vndr as installed from LK4D4/vndr@1fc68ee0 (preserve directories with .c files, 2018-04-30).

Spot checking one of the changes, the -io/+syscall import change in github.com/containerd/cgroups/blkio.go is unwinding containerd/cgroups@77e62851 (Use /proc/diskstats to get device names, 2018-01-31), because our vendor.conf has pinned containerd/cgroups@7a5fdd83 (Merge pull request #26 from onorua/error-ignore-example, 2017-08-24) since af64e10 (Vendor in lots of kubernetes stuff to shrink image size, 2018-03-26, #554). It looks like ae89dc2 (Update containerd/cgroups repo fix perf issue, 2018-02-01, #284) updated the vendored file without updating vendor.conf.

We'll probably want to go through and update vendor.conf until a fresh vndr run doesn't change vendor, and I've marked this PR as a WIP until I get to that point.

Actually af64e10 (#554) didn't change the pinned containerd/cgroups@7a5fdd8, it just reordered the file and confused blame. We've pinned that version since forking from CRI-O.

@wking For containerd/cgroups and most of our other pinned libraries - we're mostly pinning specific commits not because we require specific functionality or want to depend on a specific version of a library, but to try and make sure we don't bump vendored libraries except deliberately by updating the pinned commit (and potentially break things in the process). So feel free to update pinned commits as necessary.

Rebased onto master with a8eb55e -> 3fe410d now that #749 through #752 have landed. We've shrunk the change size a bit (but more insertions, maybe in vendor/golang.org/x/crypto, for some reason?).
But we still have a ways to go:
