0f911d71a7 Refactor audio_processing/nsx: Removed usage of macro WEBRTC_SPL_MEMCPY_W16
The macro assumes int16_t pointers, but there is no check for it.

f6a99e63b6 Refactor audio_processing: Free functions return void
There is no point in returning an error when Free() fails. In fact it can only happen if we have a null pointer as object. There is further no place where the return value is used.

Affected components are
- aec
- aecm
- agc
- ns

04c50981f8 Add the Ooura FFT to RealFourier.
We are using the Ooura FFT in a few places:
- AGC
- Transient suppression
- Noise suppression

The optimized OpenMAX DL FFT is considerably faster, but currently does
not compile everywhere, notably on iOS. This change will allow us to use
Openmax when possible and otherwise fall back to Ooura.

(Unfortunately, noise suppression won't be able to take advantage of it
since it's not C++. Upgrade time?)

7ef8b12a3b Refactor audio_processing/ns: Removes usage of macro WEBRTC_SPL_MUL_16_16_RSFT
The macro is defined as
#define WEBRTC_SPL_MUL_16_16_RSFT(a, b, c) \
(WEBRTC_SPL_MUL_16_16(a, b) >> (c))

where the latter macro is in C defined as
#define WEBRTC_SPL_MUL_16_16(a, b) \
((int32_t) (((int16_t)(a)) * ((int16_t)(b))))
(For definitions on ARMv7 and MIPS, see common_audio/signal_processing/include/spl_inl_{armv7,mips}.h)

The replacement consists of
- avoiding casts to int16_t if inputs already are int16_t
- adding explicit cast to <type> if result is assigned to <type> (other than int or int32_t)
- minor cleanups like remove of unnecessary parentheses and style changes

b81e304ac0 replace inline assembly WebRtcNsx_AnalysisUpdate by intrinsics.
The modification only uses the unique part of the analysis_update
 function. Pass byte to byte conformance test on both ARMv7 and AArch64,
 and the single function performance is similar with original assembly
 version on different platforms. If not specified, the code is compiled
 by GCC 4.6. The result is the "X version / C version" ratio, and the
 less is better.

5f3965783b Remove the different block lengths in ns_core
This CL has bit-exact output.

What it does:
  * Remove the blockLen10Ms, as it is hardcoded to be equal to blockLen.
  * This makes outLen to be always zero, so it can be removed too.
  * It also avoids the need to have an outBuf, because it is not used, so it is also removed
  * Replaced blockLen10Ms by blockLen everywhere, since they were hardcoded to be equal.
  * We don't need to check if outLen is zero, because it always is, so it was removed.
  * Of course, the outBuf needs no initial set or copying around, because it is not used.

275dac2c1d Moved the filter calculation from analyze to process in ns_core
It makes sense to have it there if the analyze and process methods are called in different stages.
Tested over the entire QA set for bit exactness.

fbf3bfe172 Separate between Analyze and Process in NS
Filled the empty analyze API, separating the noise estimation from the process API.
No formatting fixes or extra refactoring has been done, to make the review process easier.
This patch has been tested for bit-exactness over the whole QA set in every aggressiveness.

37c39f3784 audio_processing: Removed use of macro WEBRTC_SPL_UMUL_16_16
The macro replaced is a trivial multiplication after explicit casts to uint16_t and uint32_t. This CL replaces its use with "*" and adds explicit casts if necessary.

Affected components:
* AECMobile
* AGC
* Noise Suppression (fixed point version)

48f2568d89 audio_processing/nsx: Bug fix that could cause divide by zero
In the fixed point version of the Noise Suppression. At one place we subtract a value in the wrong Q-domain, which later may cause a divide by zero. Going through the floating point code that particular variable should be zero if this happens, which is what the old code tried to accomplish, but in an awkward way.

The bug has been there since development, so the likelihood of actually get a divide by zero is very small.

df9fef6638 common_audio: Removed macro WEBRTC_SPL_DIV
The macro has no built-in divide by zero check. The only thing that is done is casting to int32_t.
In addition a bug was discovered where it was supposed to do a division with rounding, but instead did a division with truncation + addition by 2. This is corrected in this CL.

These files are generally not maintained and break, some contain files
that don't exist anymore and do not build anymore. If we need to add
some of these back we should really set up a bot for them.

We should avoid macros in general (see style guide) and the shift ones are particular dangerous since they assume that the user apply a non-negative shift.
