13234d3c43 Remove neon assembly for idct 16x16 and 8x8 
Tested using test/partial_idct_test.cc:DISABLED_Speed

Both gcc 4.9 and clang 3.8 from the r13 Android NDK offer improvements
using the intrinsics:
<function>    <clang asm> <gcc asm> <clang intrin> <gcc intrin>
idct16x16_256  1720ms      1703ms    1546ms         1554ms
idct16x16_10   1320ms      1247ms     518ms          488ms
idct16x16_1     107ms       108ms      64ms           68ms
idct8x8_64      924ms       931ms     866ms          989ms
idct8x8_12      826ms       824ms     519ms          514ms
idct8x8_1       172ms       166ms     110ms          125ms

idct8x8_64 isn't quite perfect (slight regression with gcc intrinsics)
but as a counter example idct16x16_10 goes from ~1300ms to ~500ms

On a sample clip, clang improved from 48.5 to 49fps and gcc stayed roughly
stable.

the intrinsics are neutral to ~20% faster on cros/android
devices when using gcc-4.9/clang-3.8.1 and gcc-4.9/clang-3.8.x from the
r13 ndk. neutral results typically came with gcc-4.9 while larger
positive gains were achieved with clang 3.8.x.

0aa3e2564f Add compiler warning flag -Wextra and fix related warnings. 
Note: some of these warnings are enabled by a combination of -Wunused
(added earlier) and -Wextra.

Cherry-picked from AOM 4790a69faaec8f03d65f64ff070f6ab4307dbb16

Expands use of (void)x; on unused variables. AOM only supports one codec
in codec_factory.h

Does not include changes to HandleDecodeResult. AOM removed
invalid_file_test.cc which does use the video parameter.

Does not enable -Wextra yet. There are more issues to fix.

df69c751a7 Don't expand to Q register for 4x4 intrapred 
The code was expanding to Q registers so that vqrshn could be used, for
vector quad round shift and narrow. If 4 values are added together,
there is a shift by 2. If 8 values, a shift by 3. Since this accounts
for any possibility of overflow, we can skip the narrowing shift.

This allows keeping the values in D registers and casting the 16 bit
value to 8 bits.

7186a2dd86 Code refactor on InterpKernel 
It in essence refactors the code for both the interpolation
filtering and the convolution. This change includes the moving
of all the files as well as the changing of the code from vp9_
prefix to vpx_ prefix accordingly, for underneath architectures:
(1) x86;
(2) arm/neon; and
(3) mips/msa.
The work on mips/drsp2 will be done in a separate change list.

5ebc8febdc Refactor vp9_idct.h file 
Separate the common coefficient constant into vpx_dsp/txfm_common.h.
Move the SSE2 macro definitions to vpx_dsp/x86/txfm_common_sse2.h.
This clears the use case of vp9_idct.h in vpx_dsp folder.

50adfdf5ba Migrate loop filter functions from vp9/ to vpx_dsp/ 
The various tap loop filter operations are common functions across
codec. This commit moves them along with SIMD optimizations to
vpx_dsp folder.
