Rename __NR_sys_io_uring* to __NR_io_uring* to match kernel headers.
The prefix traditionally used for macros describing syscall numbers
is "__NR_", not "__NR_sys_".

Applications should not need to care about this, we can pass it in
ourselves. Once the libc support is there, we won't expose this
parameter either.

- 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
