Merge remote branch 'cros/upstream' into autotest-rebase

Merged to upstream trunk@5066, from trunk@4749.

There is no way I could enlist each individual CL from the upstream here since it will blow up the changelist description field.

BUG=
TEST=
Had patched this CL into a fresh cut client to avoid any side effect.
run_remote_test bvt from both emerged location and third_party/autotest/file.

Both test passed!

We should also keep any eye on this to see how it gets propagated into cautotest server.
