Pavel Begunkov faf88dde06 io_uring: don't inline __io_get_cqe()
__io_get_cqe() is not as hot as io_get_cqe(), no need to inline it, it
sheds ~500B from the binary.

Pavel Begunkov 75d7b3aec1 io_uring: kill REQ_F_COMPLETE_INLINE
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.

Pavel Begunkov aa1e90f64e io_uring: move small helpers to headers
There is a bunch of inline helpers that will be useful not only to the
core of io_uring, move them to headers.

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

Jens Axboe 329061d3e2 io_uring: move poll handling into its own file
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.

Jens Axboe 97b388d70b io_uring: handle completions in the core
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.
