This reverts commit b25f30348b.
Bug: skia:10154
Original message:
> Add client_utils for code that is specifically for a single client.
> Move SkFrontBufferedStream into its android/ subdir. Rename the class
> to android::skia::FrontBufferedStream. Temporarily leave in
> SkFrontBufferedStream until Android updates to the new API.
>
> Add a new optional target for client_utils/android. It is built in dev
> builds for testing, and when building for the Android framework.
Deliberately do not include client_utils in Google3, since the whole
point is to only include where necessary.
