    copybit_c2d: Use a single draw call for surfaces with different rotations

    - When opening the copybit module, query the c2d driver capabilities.
    - If supported, use a single draw call for blitting surfaces with different
    orientations using the target target rotate override flag.
    - If not supported, invoke finish_copybit to draw the layers with the
    previous orientation before applying the current orientation.

    Display: Add copybit_c2d performance optimizations

    Following performance optimizations have been made to copybit_c2d
    - Club all the layers into a single draw call. When finish_copybit
    is invoked, the draw and finish are executed.
    - Send the layer blend mode to copybit.
    - If the blend is set to none, set the pre-multiplied alpha flag.
    SurfaceFlinger assumes all surfaces have pre-multiplied alpha unless
    explicitly specified. Copybit_c2d does the same.

    The following cases are currently exempt from this optimization:
    - Change in C2D target
    - The template surfaces limit has been reached
    - Max. blit object limit has been reached.
    - Change in target transform.
    - Use of any temporary source/destination surfaces.

    copybit: Add finish API

    Add the finish API to copybit. This API is used to indicate the
    end of the drawing required by the copybit client.

    - Remove unused functions
    - Do nothing for the COPYBIT_BLIT_TO_FRAMEBUFFER case when using c2d
    composition.

    copybit: Use correct alignment in get_size()

    get_size() is used to get the size required by c2d. It's alignment
    should be 32 and not 16.
