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.

This kills the last per-op switch.

Remove some dead headers we no longer need, and get rid of the
io_ring_ctx and io_uring_fops forward declarations.

This also means moving a bit more of the fixed file handling to the
filetable side, which makes sense separately too.

Convert the last spots that check for io_uring_fops to use the provided

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

Would be nice to sort out Kconfig for this and don't even compile
epoll.c if we don't have epoll configured.

Add it and use it for the epoll handling, if epoll isn't configured.

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.

This adds definitions of structs that both the core and the various
opcode handlers need to know about.

This can move request type specific cleanup into a private handler,
removing the need for the core io_uring parts to know what types
they are dealing with.

They are really just a subset of each other, just use the one type.
