Use EGL fence sync objects to emit timepoints for the beginning and the end of rendering on the GPU. The timepoints are emitted asynchronously using the sync file fds associated with the fence sync objects. The sync file fds are acquired using the facilities provided by the EGL_ANDROID_native_fence_sync extension. The asynchronous timepoint submissions are stored in a list in gl_output_state until they are executed, and any pending submissions that remain at output destruction time are cleaned up. If timelining is inactive or the required EGL extensions are not present, then GPU timepoint processing and emission are skipped. Note that the GPU timestamps returned by sync files are in the CLOCK_MONOTONIC clock domain, and are thus compatible with the timeline timestamps (which also are in the CLOCK_MONOTONIC domain).
