Do we need this "drive" namespace inside google_apis?
How about placing the function in google_apis::util?

We're moving drive related code under google_apis into google_apis::drive.
crbug.com/180808. So, putting the function here should be fine, IMHO. WDYT?

Oh, I've surely taken a look at that issue, but completely forgotten until now.
Thanks, lgtm.
