We are going to keep coroutine-wrappers code (structure-packing parameters, BDRV_POLL wrapper functions) in separate auto-generated files. So, we'll need a header with declaration of original _co_ functions, for those which are static now. As well, we'll need declarations for wrapper functions. Do these declarations now, as a preparation step.
