When building without multithreading and for a non-arm, non-x86 system,
ctx is unused.
Cleans up -Wextra warning:
unused parameter ‘ctx’ [-Werror=unused-parameter]

In vp9_pick_inter_mode(), instead of using
vp9_get_pred_context_switchable_interp(xd) to assign filter_ref,
we use a less strict condition on assigning filter_ref.
This is to reduce the probabily of entering the flow of not
assigning filter_ref and then skipping filter search.

Allows building simple targets with sane default flags.
For example, using the Android arm64 toolchain from the NDK:
https://developer.android.com/ndk/guides/standalone_toolchain.html
./build/tools/make-standalone-toolchain.sh --arch=arm64 \
--platform=android-24 --install-dir=/tmp/arm64
CROSS=/tmp/arm64/bin/aarch64-linux-android- \
~/libvpx/configure --target=arm64-linux-gcc --disable-multithread

Speed test shows the new vertical filters have degradation on Celeron
Chromebook. Added "X86_SUBPIX_VFILTER_PREFER_SLOW_CELERON" to control
the vertical filters activated code. Now just simply active the code
without degradation on Celeron. Later there should be 2 set of vertical
filters ssse3 functions, and let jump table to choose based on CPU type.

For real-time CBR mode, use model_rd_for_sb_y_large instead of
model_rd_for_sb_y for 32x32 block. In the former model, transform
might be skipped more aggressively in some condtions, which speeds
up encoding time with only a little PSNR/SSIM drop on rtc test set.
No obvious visual quality regression.
PSNR effect on different speed setting:
speed 8 rtc: 0.129% overall PSNR drop, 0.137% SSIM drop
speed 7 rtc: 0.135% overall PSNR drop, 0.062% SSIM drop
speed 5 rtc_derf: 0.105% overall PSNR drop, 0.095% SSIM drop
Speed up:
gips_motion_WHD, 1mbps: 3.29% faster on speed 7, 2.56% faster on speed8
gips_stat_WHD, 1mbps: 2.17% faster on speed 7, 1.62% faster on speed8

Due to rounding used computation, HDB variance computation may produce
slightly negative values. This commit adds clamping to make sure
output variance values for 10 and 12 to be non-negative.

This commit adds an encoder workaround to support better
compatibility with a non-compliant hardware vp9 profile 2 decoder.
The known issue with this decoder is:
The decoder assumes a wrong value, 127 instead of the correct
value of 511 and 2047, for any assumed top-left corner pixel in
UV planes for 10 and 12 bit, respectively. Such assumed
top-left corner pixel is used for INTRA prediction when a real
decoded/reconstructed pixel is not avalable, e.g. when it is
located inside the row above the top row or inside the column
left to the leftest column of a video image.

decoding is done if the decoder is available, with errors handled
accordingly. the encoded frame count should be sufficient for this test.
+ remove HandleDecodeResult() as it's redundant given the base
implementation

This commit refactors the trellis coefficient optimization process.
It saves multiplications used to generate the final dequantized
coefficients. It removes two memset operations on quantized
and dequantized coefficient sets. This improves the unit speed
by 10%.

Each time a codec is enabled or disabled with the umbrella
--enable-vpN flag, set the encoder and decoder configurations as well.
This was done as a post-processing step but doing that lost the order of
the arguments.

Since combining VPX_DL_REALTIME with VPX_RC_FIRST_PASS is basically
nonsense, ignore the user's pass setting when this happens and
behave as if the requested encode is a single pass encode.
