I'm still confused by that the other parts in this file have targets called
"xyz_mojom_bindings" with "type: none" and that contain .mojom files. Then a
target "xyz_api" which depends on the bindings target. But here the naming is
the other way around.

It seems like this target should be called "audio_output_mojom_bindings" and the
other "audio_output_<something suitable>". What <something suitable> should be I
don't know. "api" as the others?

Can someone with mojo experience suggest?

the way it is now is consistent with other gyp files (although they're not all
consistent :( ). i.e. see
https://code.google.com/p/chromium/codesearch#chromium/src/components/leveldb...

This ugliness will go away once we leave gyp. But in the meantime, we need this
so that targets which need the generated headers, but don't want to actually
link with them, can have something to depend on.
