I added these files to (hopefully) help the reviewer having a better picture of
where I want to go and everything fits together.

Include them in the build, and make stub implementations (returning nullptr, 0,
whatever, and possibly also annotate them with FATAL() from checks.h).

[AleBzk, 2017/03/27 08:24:13]

Done.

This dep will be used to borrow WavReader, which is used via the adapter defined
in wavreader_adaptor.h
