io_uring/eventfd: move eventfd handling to separate file This is pretty nicely abstracted already, but let's move it to a separate file rather than have it in the main io_uring file. With that, we can also move the io_ev_fd struct and enum out of global scope. Signed-off-by: Jens Axboe <axboe@kernel.dk>

io_uring/eventfd: move refs to refcount_t atomic_t for the struct io_ev_fd references and there are no issues with it. While the ref getting and putting for the eventfd code is somewhat performance critical for cases where eventfd signaling is used (news flash, you should not...), it probably doesn't warrant using an atomic_t for this. Let's just move to it to refcount_t to get the added protection of over/underflows.
