[VDPAU] [PATCH 1/1] Add AV1 decode support in VDPAU API

[Manoj Bonda]

Tile_info consists of tile_offsets and tile_sizes 
In nvdec this is passed through ctx->slice_offsets present in 
NVDECContext

However vdpau_picture_context doesn't have this field to pass the 
tile_offsets and tile_sizes to the driver. Hence added tile_info as 
part of VdpPictureInfoAV1 to pass the required information to the driver.

Yes I have a rough implementation of ffmpeg which was run through 
few AV1 clips.

Thanks,
ManojGupta.
