[PATCH 00/51] tests/qtest: Enable running qtest on Windows

[Bin Meng]

In prepartion to adding virtio-9p support on Windows, this series
enables running qtest on Windows, so that we can run the virtio-9p
tests on Windows to make sure it does not break accidently.

Patch 1-22 updates various components (mostly test cases) so that
they can build on Windows with the same functionality.

Patch 23 supports the qtest accelerator for Windows.

Patch 31 updates the libqtest core for Windows.

Patch 32-47 are the fixes of qtest errors exposed when running on Windows.

Patch 49 fixes the instability of running qtests on Windows.

Patch 50 updates the CI to run qtests on Windows.

Patch 51 documents best practices of writing portable test cases as
we learned during the enablement of running qtest on Windows.
