glib/gobject/tests/genmarshal.py
Chun-wei Fan 75e3f92cd0 GObject: Fix mkenums.py and genmarshal.py tests on Windows 
The two test scripts actually assumed some *NIX paradigms, so we need
to adapt them so that they can work on Windows as well, the changes are
namely:

-Call the glib-mkenums and glib-genmarshal Python scripts with the
 Python interpreter, not just relying on shebang lines, on Windows.
 This is because the native Windows console (cmd.exe) does not support
 shebang lines, for subprocess.run().

-Use NamedTemporaryFile with delete=False, otherwise Windows cannot find
 the temp files we need when running the tests.

-Use universal_newlines=True for subprocess.run() so that we do not need
 to worry out line ending differences on different systems.

-Make sure we are not in the temp directories we create, where the tests
 are being run, upon cleanup.  Windows does not like deleting
 directories that we are currently in.

This can be run when installed or uninstalled. When uninstalled, it
requires G_TEST_BUILDDIR and G_TEST_SRCDIR to be set.
The idea with this test harness is to test the glib-genmarshal utility, its
handling of command line arguments, its exit statuses, and its handling of
various marshaller lists. In future we could split the core glib-genmarshal
parsing and generation code out into a library and unit test that, and
convert this test to just check command line behaviour.
