This CL introduces the new functionality for setting
the APM parameters to the high-pass filter.

The introduction will be done in three steps:
1) This CL which introduces the new scheme and
 changes the code in webrtcvoiceengine.cc to use it.
2) Introduce the scheme into upstream code.
3) Remove the HighPassFilter interface in APM.
