macOS aio testcase

FreeBSD 13.2-RELEASE-p5 amd64

I've been trying to improved the handling of aio_read(v) and aio_write(v) in Valgrind.

One of the tests that I've been using is an existing aio test for Darwin. There seem to be lots of issues when I run it on FreeBSD.

1. aio_read with an unaddressable buffer fails on macOS but not of FreeBSD. OK that could be an implementation detail, I don't think that POSIX requires it to fail.
2. aio_return doesn't seem to clear the status after such an aio_read, et seems to remain stuck on EFAULT. To make that clear the sequence is

aio_read with NULL buf
aio_return
aio_read with valid buf

3. doing 2 consecutive aio_reads doesn't get a fail from the second - I would expect the second to fail unless there has been a successful aio_return

4. doing a duplicate aio_return also does not fail

5. all the above points also apply to aio_write

I haven't checked the v versions yet

Added the Darwin testcase as an attachment.
