It is not possible to install barrier.h and compat.h into the top-level
/usr/include directly since they are likely to conflict with other
software. io_uring.h could be confused with the system's kernel header
file.
Put liburing headers into <liburing/*.h> so there is no chance of
conflicts or confusion.
Existing applications continue to build successfully since the location
of <liburing.h> is unchanged. In-tree examples and tests require
modification because src/liburing.h is moved to src/include/liburing.h.

This example misses an increment though the iovecs array. This causes
the same buffer to be filled from the block device every time. It would
be good to fix this since it is one of the first examples a new-comer to
io_uring is exposed too.

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.
