898897 - Update GonkDisplayJB to support JB MR2

Status: RESOLVED FIXED

(Core Graveyard :: Widget: Gonk, defect)

Attachment: Add support for JB MR2 in GonkDisplay code

A couple things got renamed in the update -

SurfaceTextureClient -> Surface
ISurfaceTexture -> IGraphicBufferProducer

Additionally, the layer setup has been adjusted a bit to be more compatible with the AOSP qcom hwc module. I don't think that module really expects to see HWC_BACKGROUND layers, so it ends up doing some things it shouldn't do. There's a couple of fixes in here which makes things more compatible, though the thing that's really necessary to fix n4 compatibility is setting displayFrame on the first layer.
