Original commit message from CVS: * gst/gstmodule.c (init_gst): Add constants for GST_*SECOND. (python_do_pending_calls): New idler handler, similar to pygtk, so python events (eg KeyboardInterrupt) can be raised during mainloop * gst/gst.override (_wrap_gst_bin_get_list): (_wrap_gst_pad_tp_repr, caps_length, caps_item) (structure_length, structure_subscript) (_wrap_gst_structure_tp_repr): Impl. (_wrap_gst_main): Override with threading blocking. * gst/gst-types.defs (Object): add flags field. (Structure): Add copy/release funcs * gst/__init__.py (devloc): Don't initialize threads * gst/Makefile.am: clean up * examples/gst/player.py: Prettify and simplify. Uses GstThread now. * examples/gstplay/player.py: Update to new api and make it work.
