Original commit message from CVS: Base on Patch by: Olivier Crete <tester at tester dot ca> * gst/gstbin.c: (gst_bin_init), (gst_bin_add_func), (gst_bin_remove_func), (update_degree), (gst_bin_sort_iterator_new), (gst_bin_handle_message_func): Keep track of pads that are being linked/unlinked and resync the state changes. * gst/gstpad.c: (gst_pad_get_direction), (gst_pad_set_chain_function), (gst_pad_set_getrange_function), (gst_pad_set_checkgetrange_function), (gst_pad_unlink), (gst_pad_link_prepare), (gst_pad_link), (gst_pad_event_default_dispatch), (gst_pad_chain), (gst_pad_push), (gst_pad_check_pull_range), (gst_pad_get_range), (gst_pad_pull_range): Some code cleanups, use macros to check pad direction. Don't need to take the lock on the pad direction. Post structure change when pads are linked/unlinked. Change some checks into _return_if_fail(). * tests/check/gst/gstbin.c: (test_link_structure_change_state_changed_sync_cb), (GST_START_TEST), (gst_bin_suite): Add testcase for pad link/unlinke resync during a state change. Fixes #510354.
