[PATCH v4 00/54] tests/qtest: Enable running qtest on Windows

[Bin Meng <bmeng.cn@gmail.com>]

In preparation 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.

Changes in v4:
- Do not use g_autofree and g_steal_pointer
- Update the error reporting by using the GError "error" argument
  of g_dir_make_tmp()
- Remove the const from tmpfs declaration
- Replace the whole block with a g_assert_no_error()
- Replace the error reporting with g_assert_no_error()
- Update error reporting
- Move the new text section after the "QTest" section instead
- Use plural in both cases: "on POSIX hosts as well as Windows hosts"
- Use "The following list shows some best practices"
- Fix typo of delimiter
- New patch: "tests/qtest: boot-serial-test: Close the serial file before starting QEMU"
- Drop patch: "chardev/char-file: Add FILE_SHARE_WRITE when openning the file for win32"

Changes in v3:
- Remove unnecessary "error = NULL" statements
- Split to a separate patch

- Use g_autofree to declare the variable
- Change to use g_mkdir()
- Change to use g_mkdir()
- Change to use g_mkdir()
- Change to skip only part of the virtio-net-test cases that require
  socketpair() intead of disabling all of them
- Introduce a new variable qtests_filter and add that to the
  qtests_ARCH variables
- Add a comment in the code to explain why test_qmp_oob test case
  is skipped on win32
- Replace signal by the semaphore on posix too
- Use __declspec(selectany) for the common weak symbol on Windows
- Introduce qemu_send_full() and use it
- Move the enabling of building qtests on Windows to a separate
  patch to keep bisectablity
- Call socket_init() unconditionally
- Add a missing CloseHandle() call
- Drop ahci-test.c changes that are no longer needed
- Change the place that sets IO redirection in the command line
- Change to a busy wait after migration is canceled
- new patch: "io/channel-watch: Drop the unnecessary cast"
- Change the timeout limit to 90 minutes
- new patch: Display meson test logs in the Windows CI
- new patch: "tests/qtest: Enable qtest build on Windows"
- Minor wording changes
- Drop patches that were already applied in the mainline
- Drop patch: "qga/commands-posix-ssh: Use g_mkdir_with_parents()"
- Drop patch: "tests: Skip iotests and qtest when '--without-default-devices'"
- Drop patch: "tests/qtest: Fix ERROR_SHARING_VIOLATION for win32"
