VAD refactor: int return value for Init.

For consistency and as part of style, the return value of WebRtcVad_Init() has been changed to int.

Impact:
 1) audio_processing, audio_coding, a test in CNG, functionTest in audio_conference_mixer, a test in net_eq all used int values. Hence, unaffected.
 2) Function pointers in net_eq changed.
 3) The VADInit in neteq/dsp.c boiled down to typecast into int anyhow, which now is removed.

TEST=vad_unittests, neteq_unittests
