The node tree evaluator now calls a callback for every used socket with its corresponding value(s). Right now the callback does nothing. However, we can use it to collect attribute name hints, socket values for debugging or data that will be displayed in the spreadsheet. The main difficulty here was to also call the callback for sockets in nodes that are not directly executed (such as group nodes, muted nodes and reroutes). No functional changes are expected.
