Turns on AVX when the final characters of .c and .cc file names preceding the
.c and .cc file extension contain the substrings avx or avx2. This silences
many MSVC warnings issued during compilation files that use AVX.

This function is deprecated after the re-design of partition search
that runs big block size, then four-way split, followed by
rectangular block sizes. This commit removes the related functions.

The function rd_pick_reference_frame can be deprecated. Its use was
subsumed by the adaptive motion search control.

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.

In real time encoding, we enable encode_breakout to make encoding
fast. A speed feature "use_encode_breakout" is defined to set
encode_breakout thresholds for different speeds.
However, currently, static_thresh is an encoder option. The encode_
breakout can be turned off if user sets static_thresh=0 specifically.
The rtc set borg test result: (need to set --static_thresh=1)
speed -5, psnr loss -3.543%;
speed -4, psnr loss -2.358%;
speed -3, psnr loss -0.771%.
Encoding speed test:
speed -5, 11% - 60% speedup;
speed -4, 5.5% - 28% speedup;
speed -3, 0.8% - 7% speedup.

Aq 1 only updates segment map on kf and arf and
only uses 3 segments. With these settings AQ1 is
+ for most clips in SSIM but negative in psnr.
However, the penalty in PSNR is much less than
previously.
Old version aq1 average results for std hd
-20.899% psnr, -5.809% SSIM
New version aq1 for std hd
-3.57% psnr, +1.23% SSIM
Aq2 Now uses only 2 segments and rd.
This mode is still slightly negative for most clips on
psnr and SSIM but seems to have a much bigger visual
impact on several problem clips than aq mode 1.
Old results for std hd:
-2.578% psnr, -1.151% SSIM
New results for std hd:
-1.561% psnr, -0.85% SSIM
