Original commit message from CVS: * libs/gst/base/Makefile.am: * libs/gst/base/gstdataqueue.c: (gst_data_queue_get_type), (gst_data_queue_base_init), (gst_data_queue_class_init), (gst_data_queue_init), (gst_data_queue_new), (gst_data_queue_cleanup), (gst_data_queue_finalize), (gst_data_queue_locked_flush), (gst_data_queue_locked_is_empty), (gst_data_queue_locked_is_full), (gst_data_queue_flush), (gst_data_queue_is_empty), (gst_data_queue_is_full), (gst_data_queue_set_flushing), (gst_data_queue_push), (gst_data_queue_pop), (gst_data_queue_drop_head), (gst_data_queue_set_property), (gst_data_queue_get_property): * libs/gst/base/gstdataqueue.h: New GstDataQueue object for threadsafe queueing. Most useful for elements that need some queueing functionnality. * docs/libs/gstreamer-libs-docs.sgml: * docs/libs/gstreamer-libs-sections.txt: Insert documentation for GstDataQueue * plugins/elements/Makefile.am: * plugins/elements/gstelements.c: * plugins/elements/gstmultiqueue.c: (gst_multi_queue_base_init), (gst_multi_queue_class_init), (gst_multi_queue_init), (gst_multi_queue_finalize), (gst_multi_queue_set_property), (gst_multi_queue_get_property), (gst_multi_queue_request_new_pad), (gst_multi_queue_release_pad), (gst_single_queue_push_one), (gst_multi_queue_item_destroy), (gst_multi_queue_item_new), (gst_multi_queue_loop), (gst_multi_queue_chain), (gst_multi_queue_sink_activate_push), (gst_multi_queue_sink_event), (gst_multi_queue_getcaps), (gst_multi_queue_bufferalloc), (gst_multi_queue_src_activate_push), (gst_multi_queue_acceptcaps), (gst_multi_queue_src_event), (gst_multi_queue_src_query), (wake_up_next_non_linked), (compute_next_non_linked), (single_queue_overrun_cb), (single_queue_underrun_cb), (single_queue_check_full), (gst_single_queue_new): * plugins/elements/gstmultiqueue.h: New multiqueue element, using GstDataQueue. Used for queuing multiple streams. Closes #344639 and #347785
