receive a signal level to use initially, instead of the
default initial signal level.
The initial form of the CL
(https://codereview.webrtc.org/2254973003/) was reverted
due to down-stream dependencies. These have been resolved,
but the CL needed to be revised according to the new scheme
for passing parameters to the audio processing module.
Therefore, please review this CL as if it is new.

code which is not thread-safe in the sense that the
rdft_init method can only be run in a single-threaded.
Currently, inside WebRTC multiple instances of the audio-
processing module are set up which means that the init
method may be run concurrently.
In order to avoid having to protect the init method with
a lock to ensure single-threaded behavior that, this CL
places the FFT functionality inside a class so that there
is no global component of the FFT functionality.
Note that:
1) The nonstandard header for the ooura_fft.cc was copied
from the aec_rdft.cc header, and augmented with a
description of the changes introduced in this CL.
2) The clang warnings for the ooura_fft_sse2.cc,
ooura_fft_neon.cc and ooura_fft_mips.cc were not
addressed as this code was kept as it was before this CL
3) Clang-format was run on all files apart from
ooura_fft_mips.cc (as that would change the format of
the inline assempbly code).
Adding bypass of presubmit to avoid code style and header errors caused by the fact that files with legacy code are being renamed.

behavior of the audio processing module is quite complex and hard to
implement in a threadsafe and efficient manner. Therefore a new
scheme for setting the parameters in the audio processing module is
introduced in this CL.
The idea is to roll this scheme out gradually and as a first functionality
in the audio processing module where this is applied the level controller
was chosen. This CL includes the replacement of the Config-based
level controller scheme with the new scheme.

Reason for revert:
Interface change in the mock breaks downstream code.

This caused build breakage due to upstream dependencies.
These dependencies need to be resolved before landing the CL.

It does:
-Handle saturations in a better manner by adding different gain change
step sizes for upwards and downwards changes, as well as when there
is saturation.
-Handle conditions with initial noise-only regions in a better way by
setting a high initial peak level estimate which is gradually reduced until
certainty about the peak level is achieved.
-Limit the maximum gain to limit noise amplification, and to reflect that it
initially is intended to be used in cascade with the fixed digital AGC mode.
-Lower the maximum allowed stationary noise floor to reduce the risk of
excessive noise amplification.
-Lower the target gain to reduce the risk of causing the AEC on the other
end to fail due to high playout levels triggering nonlinearities.
This also reduces the risk for saturation.
-Handle the noise-only regions in a better manner.
