gst/playback/gstplaybin2.c: Fix some comments and docs.
Original commit message from CVS: * gst/playback/gstplaybin2.c: (gst_play_bin_class_init), (gst_play_bin_set_uri), (gst_play_bin_set_suburi), (no_more_pads_cb), (drained_cb), (group_set_locked_state_unlocked), (activate_group), (deactivate_group), (groups_set_locked_state), (gst_play_bin_change_state): Fix some comments and docs. Post an error message when we fail to link the selector to the sink. Remove pushing of EOS, this seems unneeded. Lock the state of deactivated groups so that they don't accidentally reactivate when the playbin2 state changes. Reuse uridecodebins. Unlock and relock state of groups when playbin goes to NULL. Fixes #566654. Fixes #566341. * gst/playback/gsturidecodebin.c: (pad_removed_cb), (type_found): Only do something in the pad removed callback when we are dealing with our sourcepads because the sinkpads don't have a ghostpad.
