aio-posix: zero out io_uring sqe user_data

liburing does not clear sqe->user_data. We must do it ourselves to avoid
undefined behavior in process_cqe() when user_data is used.

Note that fdmon-io_uring is currently disabled, so this is a latent bug
that does not affect users. Let's merge this fix now to make it easier
to enable fdmon-io_uring in the future (and I'm working on that).

aio: remove aio_disable_external() API

All callers now pass is_external=false to aio_set_fd_handler() and
aio_set_event_notifier(). The aio_disable_external() API that
temporarily disables fd handlers that were registered is_external=true
is therefore dead code.

Remove aio_disable_external(), aio_enable_external(), and the
is_external arguments to aio_set_fd_handler() and
aio_set_event_notifier().

The entire test-fdmon-epoll test is removed because its sole purpose was
testing aio_disable_external().

qemu/atomic.h: rename atomic_ to qatomic_

clang's C11 atomic_fetch_*() functions only take a C11 atomic type
pointer argument. QEMU uses direct types (int, etc) and this causes a
compiler error when a QEMU code calls these functions in a source file
that also included <stdatomic.h> via a system header file:

$ CC=clang CXX=clang++ ./configure ... && make
../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid)

Avoid using atomic_*() names in QEMU's atomic.h since that namespace is
used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h
and <stdatomic.h> can co-exist. I checked /usr/include on my machine and
searched GitHub for existing "qatomic_" users but there seem to be none.

This patch was generated using:

$ git grep -h -o '\<atomic\(64\)\?_[a-z0-9_]\+' include/qemu/atomic.h | \
sort -u >/tmp/changed_identifiers
$ for identifier in $(</tmp/changed_identifiers); do
sed -i "s%\<$identifier\>%q$identifier%g" \
$(git grep -I -l "\<$identifier\>")
done

I manually fixed line-wrap issues and misaligned rST tables.

aio-posix: don't duplicate fd handler deletion in fdmon_io_uring_destroy()

The io_uring file descriptor monitoring implementation has an internal
list of fd handlers that are pending submission to io_uring.
fdmon_io_uring_destroy() deletes all fd handlers on the list.

Don't delete fd handlers directly in fdmon_io_uring_destroy() for two
reasons:
1. This duplicates the aio-posix.c AioHandler deletion code and could
become outdated if the struct changes.
2. Only handlers with the FDMON_IO_URING_REMOVE flag set are safe to
remove. If the flag is not set then something still has a pointer to
the fd handler. Let aio-posix.c and its user worry about that. In
practice this isn't an issue because fdmon_io_uring_destroy() is only
called when shutting down so all users have removed their fd
handlers, but the next patch will need this!

aio-posix: signal-proof fdmon-io_uring

The io_uring_enter(2) syscall returns with errno=EINTR when interrupted
by a signal. Retry the syscall in this case.

It's essential to do this in the io_uring_submit_and_wait() case. My
interpretation of the Linux v5.5 io_uring_enter(2) code is that it
shouldn't affect the io_uring_submit() case, but there is no guarantee
this will always be the case. Let's check for -EINTR around both APIs.

Note that the liburing APIs have -errno return values.

When a file descriptor becomes ready we must re-arm POLL_ADD. This is
done by adding an sqe to the io_uring sq ring. The ->need_wait()
function wasn't taking pending sqes into account and therefore
io_uring_submit_and_wait() was not being called. Polling for cqes
failed to detect fd readiness since we hadn't submitted the sqe to
io_uring.

aio-posix: fix io_uring with external events

When external event sources are disabled fdmon-io_uring falls back to
fdmon-poll. The ->need_wait() callback needs to watch for this so it
can return true when external event sources are disabled.

It is also necessary to call ->wait() when AioHandlers have changed
because io_uring is asynchronous and we must submit new sqes.

Both of these changes to ->need_wait() together fix tests/test-aio -p
/aio/external-client, which failed with:

test-aio: tests/test-aio.c:404: test_aio_external_client: Assertion `aio_poll(ctx, false)' failed.
