Now that we are not maintaining boilerplate code for coroutine wrappers, there is no more sense in keeping the extra indirection layer of bdrv_prwv(). Let's drop it and instead generate pure bdrv_preadv() and bdrv_pwritev(). Currently, bdrv_pwritev() and bdrv_preadv() are returning bytes on success, auto generated functions will instead return zero, as their _co_ prototype. Still, it's simple to make the conversion safe: the only external user of bdrv_pwritev() is test-bdrv-drain, and it is comfortable enough with bdrv_co_pwritev() instead. So prototypes are moved to local block/coroutines.h. Next, the only internal use is bdrv_pread() and bdrv_pwrite(), which are modified to return bytes on success. Of course, it would be great to convert bdrv_pread() and bdrv_pwrite() to return 0 on success. But this requires audit (and probably conversion) of all their users, let's leave it for another day refactoring.
