copybit blit may not be effective if data for composition
is high. Add configurable threshold support beyond which
we can avoid copybit blit. set default threshold value to
2 times of fb resolution.

When blending translucent layers or transitioning with c2d,
sometimes the frame is blended with stale framebuffer content.
Clear the frame with C2D fill surface before drawing.

The earlier copybit solution involved blitting directly into
the SurfaceFlinger's framebuffer target. That solution involved
unnecessary framework changes and caused issues when the
framebuffer was being written to both by GL and copybit.
Update hwc_copybit to use our own buffers for this purpose.
We also make sure we display only the region we're interested in
so that unnecessary artifacts from previous blits do not show up
on the display. This way, we can avoid clearing the intermediate
buffers every frame.

- Add CopybitEngine to hwc_context
- draw the layer on the HWC_FRAMEBUFFER_TARGET using
copybit(c2d) if it qualifies for C2D composition.
- use fence returned from the copybit during c2d
composition

* Use the vsync uevents from the kernel to start
surfaceflinger composition.
* This patch also does some code cleanup
- Move copybit specific functions to copybit files.
- Cleanup verbose logging.

for MDP3 targets.
