Build it\ndynamically in CameraDevice::sendCaptureResults() instead.\n\nThis requires storing the result metadata created in\nCameraDevice::requestComplete() in the Camera3RequestDescriptor. A side\neffect of this change is that the request metadata lifetime will match\nthe Camera3RequestDescriptor instead of being destroyed at the end of\nrequestComplete(). This will be needed to support asynchronous\npost-processing, where the request completion will be signaled to the\ncamera service asynchronously from requestComplete().\n\nSigned-off-by: Laurent
