display separately.
2. Add support to dump output layer for virtual display.
3. Add binder support to enable dump on each display, to enable dump
for input/output layers, and to set number of frames to be dumped.
Syntax:
adb shell "service call display.qservice 21 i32 <FRAME_COUNT> i32
<DISPLAY_TYPE> i32 <LAYER_TYPE>"
FRAME_COUNT = Number of frames to be dumped.
DISPLAY_TYPE = 1 -> To enable dump on primary display
2 -> To enable dump on hdmi display
4 -> To enable dump on virtual display
LAYER_TYPE = 1 -> To enable input layer dump
2 -> To enable output layer dump
To dump 2 frames of input and output layers on virtual display:
adb shell "service call display.qservice 21 i32 2 i32 4 i32 3"

output buffer changes.
5. Destroy virtual display, if the current virtual display list is
invalid or the output buffer handle is NULL.

5. Validate the rotator configurations and submit the rotation job
using rotator validate and rotator commit ioctl.
