Bring back slice-based threading support
Enabled with --sliced-threads
Unlike normal threading, adds no encoding latency.
Less efficient than normal threading, both performance and compression-wise.
Useful for low-latency encoding environments where performance is still important, such as HD videoconferencing.
Add --tune zerolatency, which eliminates all x264 encoder-side latency (no delayed frames at all).
Some tweaks to VBV ratecontrol and lookahead (in addition to those required by sliced threading).
