Remove PushResampler<T>::InitializeIfNeeded

This switches from accepting a sample rate and convert to channel
size over to accepting the channel size.

Instead of InitializeIfNeeded:

* Offer a way to explicitly initialize PushResampler via the ctor
  (needed for VoiceActivityDetectorWrapper)
* Implicitly check for the right configuration from within Resample().
  (All calls to Resample() were preceded by a call to Initialize)

As part of this, refactor VoiceActivityDetectorWrapper (VADW):
* VADW is now initialized in the constructor and more const.
* Remove VADW::Initialize() and instead reconstruct VADW if needed.

Add constants for max sample rate and num channels to audio_util.h
In many cases the numbers for these values are embedded in the code
which has led to some inconsistency.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
