Gives the user a possibility to dynamically change the history size. The main advantage is, for example, that you now can start with a wide delay range and over time decrease the search window to lower complexity.
Adds
- two new APIs.
- and updates unit tests.
- a history_size member variable to BinaryDelayEstimator.
- two help function re-allocating buffer memory.
One thing that makes this a little complicated is that you are allowed to have multiple delay estimators with the same reference, so changing the buffer sizes at one place will automatically give you a mismatch at other places.

These changes are currently not used in webrtc/ but helps in using the delay estimator.
* The last_delay_quality() is updated with respect to robust_validation and changed to return float.
* Tests are updated wtih respect to above.
* Adds the possibility to make a soft reset based on external circumstances like a known delay shift has been made.
* The soft reset change the lookahead dynamically. An API to ask for current lookahead has been added as well.

Added is
- a member variable for turning robust validation on and off.
- API to enable/disable feature.
- API to check if enabled.
- unit tests for these APIs.
Not added is
- the actual functionality (separate CL), hence turning feature on/off has no impact currently.
- calls in AEC and AEC, where the delay estimator is used. This is also done in a separate CL when we know if it should be turned on in both components.

The changes are summarized here:
delay_estimator.*
-----------------
Replaced assert() with correct error check. This is consistent with previous versions of the delay_estimator, i.e., to check for valid parameters where they are actually used and not high up in a wrapper layer.
delay_estimator_internal.h
--------------------------
Pulled out the far-end part of DelayEstimator struct and put it in DelayEstimatorFarend. The only common parameter is spectrum_size, which we store in both and thereby avoiding having a Farend pointer in DelayEstimator.
delay_estimator_wrapper.*
-------------------------
Added and updated descriptions. From Free(), Create(), Init() the far-end parts have been put in separate Farend versions. Same goes for the Process() which now has an AddFarSpectrum() version.
The flow of calls should be something like (in pseudo-code)
far* = CreateFarend(history_size)
near* = Create(far, lookahead)
InitFarend(far)
Init(near)
while call ongoing
AddFarSpectrum(far, far_spectrum)
Process(near, near_spectrum)
end while
Free(near)
FreeFarend(far)
delay_estimator_unittest.cc
---------------------------
Added farend support setting up calls as mentioned above.
aecm_core.*
-----------
Cleaned up some lint warnings.
Added delay_estimator_farend pointer. Called Create(), Init() and Free() in above mentioned order.
If AddFarSpectrumFix() was not successfully done, we end and return -1. This is what we would have done for Process().
aec_core.*
----------
Cleaned up some lint warnings.
Added delay_estimator_farend pointer. Calls in proper order. Since we only use the delay estimator for logging there is no error handling. We only call Process() if AddFarSpectrum() was successful though.

This CL is one step in a larger change of the DelayEstimator where we will open up for multiple near-end signals.
This particular CL separates the low level far-end parts without affecting the usage externally. This is a first step towards separating the far-end and near-end parts giving the user the control.
