Is there a compelling reason to have this as a separate build file?  Having
separate files for each api has led to cyclical problems, since often an API
will depend on extensions/browser/ and extensions/browser/ will depend on this
API.

[Luke Sorenson, 2017/05/17 21:01:35]

The reason I am using a separate build file is because this API is for chromeos
only and all of the other APIs under is_chromeos in
extensions/browser/api/BUILD.gn use their own build file. Not sure exactly why
that is, but what do you suggest?

[Devlin, 2017/05/18 21:21:24]

I'd suggest having these files directly included in a chromeos-specific block in
extensions/browser/api/BUILD.gn.

Done.
