Original commit message from CVS: * gst/gstelement.c: (gst_element_get_state_func): Don't output the same debug statement twice. * libs/gst/base/gstadapter.c: (gst_adapter_try_to_merge_up), (gst_adapter_peek), (gst_adapter_take_buffer): Optimise the case where we have buffers at the head of the queue that can be joined quickly (because they're contiguous sub-buffers) by merging them together rather than copying data out into new memory. * gst/parse/grammar.y: * tests/check/pipelines/parse-launch.c: Fix a leak in an error path for parse_launch, and add a check for it to the testsuite.
