* Add a RingBuffer typedef.
* Add the ability to force a memcpy by passing a null ptr. In some cases,
we know we want a memcpy. This allows us to skip a potential
intermediate memcpy.
* Add a stress test.

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.
