ffef74885b display: Add support orientation control on ext display
- The required orientation on External can be set using the
  properyt sys.ext_orientation.
- Values can be HAL_TRANSFORM_ROT_90, HAL_TRANSFORM_ROT_270
- According to the value set, the FB_TARGET for External will
  be rotated and positioned as per aspect ratio on Ext
- For YUV(video layer) it just calculates the position, as the
  rotation should be the source orientation
- This feature is supported only for low resolution panel.

85977e3abe hwc: Implement mixed mode composition.
With this change we are moving  MDP composition from all-or-nothing
implementation to mixed mode implementation where layers can
partially be composited through MDP and while rest of the layers are
composed / cached in framebuffer.

        - Mixed mode design is based on layer caching
        - Mixed mode path is configured only when non-bypassing
          layers are cached.
        - Never allow mixed mode when FB needs to be  udpated.
        - If we cannot bypass all MDP comp marked layers, bail
          out completely.

c6a8250a1c hwc: Configure FbUpdate only when needed
When video overlay is on and there are no UI layers to compose,
there is no need to configure for framebuffer target.

If framebuffer target is  also configured in such cases, video is not
shown on display due to 0 z-order.

64b8121562 hwc: Use intermediate buffers for copybit
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.

758bfc5b50 hwc/overlay: Dynamic pipe tracking.
Remove state based pipe handling and make pipes tracked dynamically.
Add the configStart, configDone, nextPipe availablePipes APIs.
Remove setState API.

-configStart marks all pipes available.
-configDone garbage-collects unused pipe objects.
-nextPipe returns the index of next available pipe and create a corresponding
pipe object if not present
-availablePipes returns total of "unallocated" pipes. (Pipes could be allocated
but unused)

Changes in hwc adapt to the new overlay APIs.
Compile out MDP comp.
Remove unused files in overlay and hwc.
Update licenses.
