Current setting was specific to 1 layer case.
rc_target_bitrate is total bitrate for whole stream,
so set it to ts_target_bitrate for highest/top temporal layer.

Change floats to doubles in RateControlMetrics, and make loop
counter signs agree.

Only use layered average size if number_temporal_layers > 1.

Also removed unneeded commented-out line, and change some parameter
setting in vpx_temporal_scalable_patterns.c

This patch adds a buffer-based rate control for temporal layers,
under CBR mode.

Added vpx_temporal_scalable_patters.c encoder for testing temporal
layers, for both vp9 and vp8 (replaces the old vp8_scalable_patterns).

Updated datarate unittest with tests for temporal layer rate-targeting.
