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.
