Ignore the G_SPAWN_DO_NOT_REAP_CHILD flag, can't be meaninfully

	* glib/gspawn-win32.c (g_spawn_async_with_pipes): Ignore the
	G_SPAWN_DO_NOT_REAP_CHILD flag, can't be meaninfully implemented
	on Windows, at least not now. Always pass dont_wait as TRUE to
	do_spawn_with_pipes(). The semantics of the dont_wait parameter is
	very different from the semantics of the intermediate_child
	parameter to fork_exec_with_pipes() in the Unix version. This
	fixes a serious bug, g_spawn_async() in fact behaved
	synchronously.

	(do_spawn_with_pipes, do_spawn): Rename from
	fork_exec_with_pipes() and do_exec(), those names were from the
	Unix bersion, and misleading.

	(close_and_invalidate): Don't try to close invalid fds.

	* glib/gspawn.c (g_spawn_async_with_pipes): Add warning about
	Windows behaviour. There is no fork(), so the child_setup()
	function is in fact called in the parent.

	* glib/gspawn-win32-helper.c (WinMain): Insert spaces in argv
	debugging output.

	* tests/spawn-test-win32-gui.c: New file. Test program to be
	linked as a GUI application. Behaves differently depending on how
	invoked (by spawn-test).

	* tests/spawn-test.c (run_tests): On Win32, run the
	spawn-test-win32-gui program, too, in several ways, synchronously
	and asynchronously.

	* tests/Makefile.am: Corresponding change.
