[VDPAU] [PATCH] Add support for H264 Hi444PP in VDPAU API

[Karthikeyan Sreenivasan]

The current patch adds to the previous [VDPAU][PATCH] Enable Lossless
Decode Capabilities via VDPAU API. It contains the following changes,

1. Rename VdpPictureInfoH264Extended to VdpPictureInfoH264Predictive.
2. Remove version information from VdpPictureInfoH264Predictive.
3. Pointer to VdpPictureInfoH264 has been replaced with the entire
VdpPictureInfoH264 struct.
4. Addition of new flag residual_color_transform_flag to enable/disable
separate color plane coding.
