This seems like a wrong-direction dependency. Check with Elliott what we're
supposed to do here?

It does seem weird to depend on content/ from blink. But it's only really the
bindings that depend on it. Blink code will never see the BluetoothDeviceId
type. One option is to move the type to components/web_bluetooth/ which aligns
with the direction jam and rockot want us to go, but it's basically the same but
without the word "content" in the path.

[Jeffrey Yasskin, 2016/06/06 23:44:02]

I guess content/common doesn't depend on WebKit, so there aren't any cycles
here. I'm happy leaving it like this until your WebKit reviewer complains. ;)
