Original commit message from CVS: * gst/elements/gstfdsrc.c: (gst_fdsrc_init), (gst_fdsrc_get_query_types), (gst_fdsrc_get_formats), (gst_fdsrc_srcpad_query): Implement querying. * gst/gstqueue.c: (gst_queue_chain), (gst_queue_get): If we're waiting to be "full enough to start" and EOS comes in, just flow through all data since waiting longer is not going to help us. Fixes hangs on short media files played from network sources. * gst/gsttag.c: (_gst_tag_initialize): * gst/gsttag.h: Add GST_TAG_IMAGE tag.
