2. Add read/write for RC stats file
The two pass RC for svc does not work yet. This is just the first
step. We need further development to make it working.

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.

Use unsigned loop counters in set_roi_map() and set_active_map().

Change-Id: I9bbaed38b51ef73b82ba4ad4c4bc18ca5d2399f9

Use unsigned int instead of uint64_t for duration and deadline
arguments to functions get_frame_stats() and encode_frame().

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.

Right now only IVF format is supported which is enough for example code.
Other formats like y4m, webm, raw yuv will be supported later.
