	Improvement based on suggestion by Thorsten Maerz:

	* glib/giowin32.c (struct _GIOWin32Channel): Don't need thread_handle.

	(create_thread): We can close thread handle right away, it isn't
	used for anything.

	(read_thread, select_thread): Thus, don't close it here.

	Fix #57690, partial fix for #57689:

	* glib/giowin32.c (g_io_win32_set_flags): Don't set the GError,
	instead call g_warning().

	(g_io_win32_fd_get_flags_internal): New function, sets the
	is_readable, is_writeable and is_seekable flags based on the
	actual access modes of the underlying Win32 HANDLE, by trying
	Win32 ReadFile() and WriteFile() of zero bytes, and
	PeekNamedPipe(). Should work for disk files and pipes. For devices
	(consoles) unfortunately not.

	(g_io_win32_fd_get_flags): Don't set the
	G_IO_FLAG_IS_{READ,WRITE}ABLE flags, g_io_channel_get_flags()
	already does. Call g_io_win32_fd_get_flags_internal() to set the
	is_* flags.

	(g_io_win32_msg_get_flags, g_io_win32_sock_get_flags): Splice the
	generic g_io_win32_get_flags() into these specific functions, as
	they need to do different things. Not implemented yet, though.

	(g_io_channel_win32_new_fd_internal): New function, to avoid
	duplicate fstat() calls. Most code from g_io_channel_win32_new_fd()
	moved here. Call g_io_win32_fd_get_flags_internal() to set the
	is_* flags.

	(g_io_channel_win32_new_fd, g_io_channel_unix_new): Call
	g_io_channel_win32_new_fd_internal().

	(g_io_win32_no_seek): Remove. Don't set is_seekable for those
	channel types.
