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.

Ring memory is released by umapping {cq,sq}->khead, which assumes that
p->{cq,sq}_off.head will always be 0.
Add another field to for the mmaped region and use that instead of
->khead when umapping.

If the ring setup fails, close the fd before returning failure.

We really should use a ';' to terminate the line. This is just a
cosmetic issue, no functional changes.

io_uring_queue_init does not allow the caller to specify sq_thread_cpu
or sq_thread_idle. Users that want to specify those parameters need to
call io_uring_setup(2) themselves. Add a helper so that they don't also
have to hand-craft the code to map the submission and completion queues,
and setup the sqe ring. This allows those applications to still make
use of io_uring_submit and get/wait_completion.

Let's have the various helpers be in usefully named functions, no
need to bundle them all into the same one.
