To remove the dependency from extensions/ to chrome/browser, we will move our mojom files to a different directory. The current thinking is that it will go into media/mojo/interfaces.
For consistency we should also move the definition of struct traits and typemaps into the same directory, but that will also require us to move some of our C++ data structures (e.g. MediaSink).
