Make this take a GError and return a gboolean, and do the "outstanding

2007-11-30  Dan Winship  <danw@gnome.org>

	* ginputstream.c (g_input_stream_set_pending): Make this take a
	GError and return a gboolean, and do the "outstanding operation"
	check (and the "stream is already closed" check) itself.
	(g_input_stream_clear_pending): Formerly set_pending(FALSE).

	* goutputstream.c (g_output_stream_set_pending)
	(g_output_stream_clear_pending): Likewise

	* gbufferedinputstream.c:
	* gfileinputstream.c:
	* gfileoutputstream.c: Update for that

	* gsimpleasyncresult.c (g_simple_async_report_gerror_in_idle):
	Like g_simple_async_report_error_in_idle, but takes a GError
	rather than building one.
