Works just like io_uring_submit(), but also allows retrieving events
(or waiting/polling for them) in the same call.

io_uring_queue_mmap wasn't exported from the ld map file, meaning the
linker gave it private, static linkage in the resulting shared object,
as opposed to global linkage. This results in the symbol seemingly
missing at link-time, despite the existence of the symbol in the library
itself.

Some of the symbols were missing from linker version
script so they weren't exported in the dynamic library.

We have io_uring_get_sqe() on the submission side, yet the completion
side is named _completion. Rename as follows:
io_uring_get_completion() io_uring_peek_cqe()
iO_uring_wait_completion() io_uring_wait_cqe()
This better tells the user what the _get variant does by calling it
_peek instead, and we move to using _cqe() as the postfix instead
of _completion.

Missed this part when the switch was made to full 'sqe'.

This now exposes two helpers:
io_uring_get_completion()
Return a completion, if we have one (or more) available in
the ring
io_uring_wait_completion()
Return a completion, waiting for it if necessary
