This adds support for epoll manipulation through io_uring, in particular
epoll_ctl(2). Patch 1 is just a prep patch, patch 2 adds non-block
support for epoll, and patch 3 wires it up for io_uring.

Patch 2 isn't the prettiest thing in the world, but we need to do
nonblock grabbing of the mutexes and be able to back out safely.

Please review, thanks.

Since v1:

- Use right version...
- Fix locking in eventpoll
- Don't EINVAL on sqe->off in epoll prep for io_uring
