enable video rotation+scaling for WiDi usage.
BZ:188797
a). Video driver will provide 3 kinds of buffers as following:
scale rotate
normal buffer:1080P -------> scale buffer:720P -----------> rotate buffer:
specified size, such as 480P, 720P, 1080P, etc.
b). HWC will select rotate buffer and send to WiDi

Disable MDS state callback function "onMdsMessage" in video driver
BZ: 154810
2 preconditions:
1: video driver library "pvr_drv_video" uses dynamically load and unload method,
it means it releases all resource when it is unloaded;
2: Android Binder thread poll allows destruct BnBinder operation is on pending state,
and it means BnBinder destruct operation may be delayed;
Seems that we couldn't use MDS state callback function "onMdsMessage" in video driver;
Generally, this callback works fine, when video driver library is
unloaded, it will inform MDS to release Binder,
then android Binder thread pool will release Binder pointer immediately.
But sometimes, Android BnBinder destruct operation is pending,
the root cause is not clear, but it is a legal state.
When this destruct operation is ready to do, video driver has been unloaded,
and BnBinder pointer is invalid.
It means Android Binder thread pool tries to release
an invalid BnBinder pointer, and causes a crash.

Enable "IMultiDisplayListener::onMdsMessage" for video driver
BZ:150907
1: Video driver need to get some MDS infos to do futher handling.
Currently, video driver uses polliing method through interfafe
"getDisplayMode", its efficientcy is low.
Now we Use "IMultiDisplayListener::onMdsMessage" to replace it,
it means MDS will inform video driver actively once mode is change.
2: Refine vpp interface
