Move struct wait_opts and waitid_info into kernel/exit.h, and include function declarations for the recently added helpers. Make them non-static as well. This is in preparation for adding a waitid operation through io_uring. With the abtracted helpers, this is now possible. Signed-off-by: Jens Axboe <axboe@kernel.dk>
