Add the option of compressing speech input audio using FLAC.
In the process, added a generic AudioEncoder interface which could create the requested codec.
Right now the codec is set to FLAC. In a future CL, we'll determine the codec to use dynamically
based on bandwidth considerations.
This CL depends on http://codereview.chromium.org/6205006/ going in first.
