Magnus Jedvert 1d270f8193 Reland "Android: Generalize and make TextureBufferImpl public"
This reverts commit 64051d4975b5cee06ab36584f272ff97e35de357.

Reason for revert: Fix applied.

> Original change's description:
> > Android: Generalize and make TextureBufferImpl public
> > 
> > This CL generalizes TextureBufferImpl so it's useful from other contexts than
> > from a SurfaceTextureHelper, and fixes a bug in cropAndScale(). It also exposes
> > the class in the api so that clients don't have to duplicate the logic.
