I'm going to funnel all libudev access through device/udev_linux in an upcoming
CL. I'd like to do some cleanup first and move the current udev.{cc,h} aside so
I can have the libudev wrapper as udev.{cc,h}.

I'm hesitant to add a dependency on device from content for such a trivial usage

I plan on making all udev usage go through device/udev_linux. I'll prettify the
next CL a bit, rebase it against this, and upload it soon.

https://codereview.chromium.org/674703002 is roughly what I want to do next.
Lots of wrappers.

ok, looks like battery cl also added a legitimate device dependency, so lgtm
