Clean it up, and just use a single io_uring for both the reads
and the writes.

We don't need any of the information in there in the caller, and
this makes it harder to abuse as we don't require the caller to
have memset() the struct first.

- Don't use polled IO for the io_uring-test, that'll fail if the
fs/device doesn't suppor it
- copy read-in was broken for io_uring-cp

- Fixed buffers are now available through io_uring_register()
- Various thread/wq options are now dead and automatic instead
- sqe->index is now sqe->buf_index
- Fixed buffers require flag, not separate opcode

- io_uring_sqe added an index field, for fixed buffer locations
- io_uring_setup(2) system call added a 'nr_iovecs' field
