Remove struct io_poll_update from io_kiocb, and convert the poll path to
use the io_cmd_type approach instead.

Remove struct io_poll_iocb from io_kiocb, and convert the poll path to
use the io_cmd_type approach instead.
While at it, rename io_poll_iocb to io_poll which is consistent with the
other request type private structures.

Remove struct io_rw from io_kiocb, and convert the read/write path to
use the io_cmd_type approach instead.

Each opcode generally has a command structure in io_kiocb which it can
use to store data associated with that request.
In preparation for having the core layer not know about what's inside
these fields, add a generic io_cmd_data type and put in the union as
well.

Define an io_op_def->prep_async() handler and push the async preparation
to there. Since we now have that, we can drop ->needs_async_setup, as
they mean the same thing.

In preparation for splitting io_uring up a bit, move it into its own
top level directory. It didn't really belong in fs/ anyway, as it's
not a file system only API.
This adds io_uring/ and moves the core files in there, and updates the
MAINTAINERS file for the new location.
