add io_uring_queue_mmap
io_uring_queue_init does not allow the caller to specify sq_thread_cpu
or sq_thread_idle. Users that want to specify those parameters need to
call io_uring_setup(2) themselves. Add a helper so that they don't also
have to hand-craft the code to map the submission and completion queues,
and setup the sqe ring. This allows those applications to still make
use of io_uring_submit and get/wait_completion.
