Removes certain cases of feedback of active_worst_quality,
and removes it from the RATE_CONTROL structure. Now active
worst quality is expected to be computed locally in the
q picking function during the encode.
Making temporal filter strength depend on avg_frame_qindex
rather than on active_worst_quality actually improves
performance esp. for yt.
derf: +0.038%
yt: +0.359%

Some parameter changes and fixes on one-pass rate control.
derfraw300 is now only 10% below 2-pass speed 0 rate control.

Function encode_rtc_frame_internal() and encode_frame_internal() only
differed by a couple of speed features, this commit relocation those
difference into the setup of speed features and merged two functions
into one to remove duplication.
It also fixed a subtle bug super_fast_rtc was used before it was
initialized.

-Properly set the average frame size for each layer.
-Allow each layer to update its average/last Q stats after encoding.
-Initialize for some layer context variables.

A bug was reported in Issue 702: "SIGILL (Illegal instruction) when
transcoding with vp9 - using FFmpeg". It was reproduced and fixed.

Bitwise OR operation doesn't guarantee any subexpression evaluation order.
Just reading one bit now and ignoring the next one. For reference look at
vp9_decode_frame() implementation.

Fixes some of the parameters for 1-pass non-cbr mode.
Also includes some cleanups, inlcuding refactoring of the
recode_loop options.
Results on derfraw300 improve by about 5-6%, so that the one-pass
mode is now 13% below the 2-pass mode in speed 0.

this ensures both are properly initialized when calling _dealloc().
+ check the arrays before access

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.
