A function that should be called if the buffer has no more references left.
Elements that utilize hardware memory could use this to re-queue
the buffer after it's been unreferenced. If no free_data_func has been
provided, the default will be used which simply deallocates the memory
region and the GstBuffer object. Manual implementations that want to
free their own memory but don't do anything special otherwise are
suggested to set the GST_BUFFER_DONTFREE flag on the buffer and call the
default data free function (gst_buffer_default_free()) from their manual
implementation.
