With the latest 9p test case refactoring in the mainline, I will have
to cherry-pick the following 2 patches in this series, to v6 of
"tests/qtest: Enable running qtest on Windows" series [1], in order to
get qtest on Windows build successfully.

[06/16] hw/9pfs: Add missing definitions for Windows
[15/16] tests/qtest: virtio-9p-test: Adapt the case for win32

I will include the above 2 patches in the v6 qtest windows support series.
