70adcd46b2 Delay estimator improvements. 
Robustness improvements to the delay estimator used in AECM and AEC. In AEC only for logging. Faster convergence.

TEST=audioproc_unittest + offline file tests.

output_data_fixed.pb updated despite unverified changes in r1112.

6d6a43d6e3 Use char as ring-buffer data type. 
- Avoids a bunch of char* casts.
- Use enum type rather than char.

TEST=audioproc_unittest on Linux (float and fixed), build on Windows

267d0133ff Fixed pointer operations on void. 
This should fix the error on Win where pointer arithmetics are done on void pointers. Type cast to char to interpret a size.

7270a6bcc2 Merged apm-buffer branch [r1293] back to trunk. 
This CL includes a larger structural change in how we handle buffers in AEC. We now perform FFT at once and move within blocks to compensate for system delays.

a919d3a643 Don't return a zero delay with insufficient data. 
For estimating a delay over a long segment (e.g. a file) this can
throw off the estimate. Better not to add values to the AEC's histogram
until they're reliable.

6a9835d59c Delay estimator structural changes. 
Improved the way we handle different data types (float vs fixed) and reduced the complexity by nearly 50%.
We now have a generic struct for both float and fixed delay estimators and a core struct for the binary spectrum based delay estimator. All wrapper codes (for both fixed and float) are gathered in delay_estimator_wrappers.*.
Moved out the far end history buffer to AEC(M).
Added a union to handle difference types when create.

b47d4b287d This CL includes a move of the fixed point delay estimator from aecm to apm/utility. There has also been a code change that makes it possible to enable/disable the far end alignment, so that we save complexity when used as a quality metrics.

d3185fe219 refactor the gyp file to gypi file. 
Basically, the gypi file is a copy of gyp file, but has some difference on the
path of the dependencies.
