Original commit message from CVS: * ext/gnomevfs/gstgnomevfssrc.c: (gst_gnomevfssrc_get), (gst_gnomevfssrc_srcpad_query), (gst_gnomevfssrc_srcpad_event): Some debug. * gst/avi/gstavidemux.c: (gst_avi_demux_reset), (gst_avi_demux_handle_src_event), (gst_avi_demux_read_superindex), (gst_avi_demux_read_subindexes), (gst_avi_demux_add_stream), (gst_avi_demux_stream_index), (gst_avi_demux_skip), (gst_avi_demux_sync), (gst_avi_demux_stream_scan), (gst_avi_demux_massage_index), (gst_avi_demux_stream_header): * gst/avi/gstavidemux.h: Support for openDML-2.0 indx/ix## chunks. Support for broken index recovery (where, if part of the index is broken, we will still read the rest of the index and recover the broken part by stream scanning). More broken media support. EOS workarounds. General AVI braindamage headache recovery. Aspirin included.
