common_audio/signal_processing: Remove unused macros WEBRTC_SPL_GET_BYTE and WEBRTC_SPL_SET_BYTE

These two macros are not used anywhere in webrtc. Previously used in old neteq (I think).

Remove unneeded WebKit dependency from DEPS.

This dependency was added in r4173 in order to support
the build/android/run_tests.py script.
In http://crrev.com/217588 that script was removed and
build/android/test_runner.py was the preferred script to
launch Android tests with.
Also in http://crrev.com/279515 the dependency on webkitpy
was removed and replaced by copies of the needed files in
build/android/pylib/utils/.

MIPS optimizations for ISAC (patch #3)

Implemented functions:
- WebRtcIsacfix_MatrixProduct1
- WebRtcIsacfix_MatrixProduct2

The optimizations are bit-exact to the C code.

replace inline assembly WebRtcNsx_PrepareSpectrumNeon by intrinsics.

The modification only uses the unique part of the spectrum (as is done for the C and asm code). It passes
byte to byte conformance test, and the single function performance
(if not specified, the code is compiled by GCC 4.6) on different
platforms:

| run 100k times             | cortex-a7 | cortex-a9 | cortex-a15 |
| use C as the base on each  |  (1.2Ghz) |  (1.0Ghz) |   (1.7Ghz) |
| CPU target                 |           |           |            |
|----------------------------+-----------+-----------+------------|
| C                          |      100% |      100% |       100% |
| Neon asm                   |       18% |       14% |        19% |
| Neon inline asm            |       31% |       25% |        27% |
| Neon intrinsic (GCC 4.6)   |       33% |       27% |        42% |
| Neon intrinscis (GCC 4.8)  |       17% |       14% |        19% |
| Neon intrinsics (LLVM 3.3) |       15% |       13% |        18% |

GN: Fixes for Chromium builds.

When building WebRTC from a Chromium checkout (i.e. with
https://codereview.chromium.org/321313006/ applied) GN
cannot execute successfully.

This CL fixes:
- include path for video_processing module's SSE2 target.
- NSS/SSL targets

Precompute the AEC FFT tables, rather than initializing at run-time.

These global arrays are shared amongst all AEC instances, and were at
serious risk of data races. A Chromium TSAN bot recently caught this.

Also move the function pointer selection for optimization to
create-time. (Ideally this would only be done once.)
