Bug: 23535524
Two APIs added for multiframe processing:
- createAllocations(...): To create an array of Allocations sharing the
same Type and Usage. For USAGE_IO_INPUT Allocations, they also share
the same BufferQueue.
- getTimeStamp(): API to retrieve the time stamp associated with the
most recent buffer.
