We already have the declarations in opdef.h, move the rest into its own
file rather than in the main io_uring.c file.

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.

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.

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

There's a special case for recvmsg with MSG_ERRQUEUE set. This is
problematic as it means the core needs to know about this special
request type.
For now, just add a generic flag for it.

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.
