This change adds back the property overrides for several device
types as we had in CM 11.

It contains a squished commit of the following:

    Reduces after boot memory footprint by about 5-8MB
    Note: This is for low memory based devices only (~512MB RAM
    or less)

SurfaceFlinger: Add support for virtual display

- Creates a rendering surface when invoked via hybrid path

sf: vds: Selectively compose displays via HWC.

1. Replace static force copy flag with member variable

The decision to copy a virtual display using the WriteBack path will be
done when the display is created. We initialize the member variable to
false meaning all virtual display devices are composed via GLES.

2. Select which displays to compose based on sink usage flags

We should compose a display using HWC only if the sink usage contains
GRALLOC_USAGE_PRIVATE_WFD and GRALLOC_USAGE_HW_VIDEO_ENCODER flags.

If this condition is not met then the display is composed using GLES.
This means that GLES composes directly into the sink buffer and signals
the consumer. Furthermore, it is expected that any color conversion will
be handled on the consumer side.

3. Add debug hook for ScreenRecord use case

We add a debug hook which serves to by-pass the checks imposed by (2).
This is useful for debugging purposes and allows us to test VDS
end-to-end when WFD is not working on a particular build.

The debug hook is through the system property: debug.hwc.screenrecord

4. Update composition checks

-mFbProducerSlot is always at least 0 so there is no point in validating
 it when in advanceFrame().
-Release scratch buffers in onFrameCommitted as long as mFbProducerSlot
 is valid.

frameworks/native: Reset dirtyRect after every queuebuffer call.

Sometimes HWR does not generate dirtyRect even when it updates the

cached dirtyRect after every queueBuffer call.

SurfaceFlinger: Change to support framebuffer flip for 2D blitters

- Surfaceflinger does not flip framebuffers when there are
  no layers marked for HWC_FRAMEBUFFER
- This change checks for the HWC_BLIT flag and will request a flip
  to a new FB_TARGET buffer even if there are no FRAMEBUFFER layers

SF: Modify logic to handle "transparent Region" for displayFrame

sourceCrop and displayFrame calculations according to "transparent Region"
are not synchronized. Because of this mismatch scaling is introduced,
causing corruption in UI. To avoid this scaling, map displayFrame to
sourceCrop, apply reduce and remap result to displayFrame.

play.

Reduce transparent region from a layer only if the transparent
region has valid intersection with the layer. Otherwise, reducing
a transparent region lying completely outside of the layer leads to
invalid sourcecrop values for the layer.
