Initialize internal buffer pointers in rtc mode
In rtc coding mode, the encoder is running non-RD mode decision. It
does not need dual buffer swap as was the case in the RD mode. This
commit initializes the internal buffer pointers outside the block
coding loop for rtc mode.

Remove some cases for turning off arf.
Flipping arf on and off too often is hurting some clips.
This change makes no difference for 50-75% of our test
clips but helps some by a big margin. (eg. std-hd crew
by 6% and one of the YT and YT-hd clips by 14%)
Average improvements for 2 pass, speed 2 (psnr,ssim)
are as follows:-

decode_test_driver: Use size_t for size arg to DecodeFrame().
Use size_t for DecodeFrame()'s size arg, and cast only
at the vpx_codec_decode() call site. This silences warnings that
appear in svc_test.cc when building with vs2013.

Remove unnecessary vp9_setup_buffer_inter use
This function initializes the predictor buffer pointers and
calculates reference motion vectors. It is only needed in the settings
of inter frame coding. Hence removing it from the key frame coding
branch in rtc_use_partition.

gen_msvs_vcxproj.sh: Add /arch:AVX for files using AVX.
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.

Removes active_worst_quality feedback
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%

Enable encode_breakout in real time encoding
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%.

Modified Aq1 and Aq2
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

Add get release decoder frame buffer functions.
This CL changes libvpx to call a function when a frame buffer
is needed for decode. Libvpx will call a release callback when
no other frames reference the frame buffer. This CL adds a
default implementation of the frame buffer callbacks. Currently
only VP9 is supported. A future CL will add support for
applications to supply their own frame buffer callbacks.

Merged two similar functions to reduce duplication
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.
