Only send a buffer when we have received a NEED_DATA message. Add a signal to pulla buffer from the sink. Restructure the sink to use a queue like the source and only push a buffer when we can. Improve SpaData. Offset and size should be between 0 and maxsize, make sure we clamp correctly when needed. node_process_output completes the processing of the output after receiving HAVE_OUTPUT for async elements. It instructs the node that it now can produce more output.
