Deduplicate some code and add a helper for filling an aux CQE, locking
and notification.

REQ_F_COMPLETE_INLINE is only needed to delay queueing into the
completion list to io_queue_sqe() as __io_req_complete() is inlined and
we don't want to bloat the kernel.
As now we complete in a more centralised fashion in io_issue_sqe() we
can get rid of the flag and queue to the list directly.

There is a bunch of inline helpers that will be useful not only to the
core of io_uring, move them to headers.

Move both the opcodes related to it, and the internals code dealing with
it.

This also helps cleanup the io_uring.h cancel parts, as we can make
things static in the cancel.c file, mostly.

Add a io_poll_issue() rather than export the general task_work locking
and io_issue_sqe(), and put the io_op_defs definition and structure into
a separate header file so that poll can use it.

While at it, convert the handlers to just use io_eopnotsupp_prep()
if CONFIG_NET isn't set.

This splits out splice and tee support.

Normally request handlers complete requests themselves, if they don't
return an error. For the latter case, the core will complete it for
them.
This is unhandy for pushing opcode handlers further out, as we don't
want a bunch of inline completion code and we don't want to make the
completion path slower than it is now.
Let the core handle any completion, unless the handler explicitly
asks us not to.
