The current record macros already log the function being called. This patch extends the macros to also log their input arguments and removes explicit logging from the SB API. This might degrade the amount of information in some cases (because of smarter casts or efforts to log return values). However I think this is outweighed by the increased coverage and consistency. Furthermore, using the reproducer infrastructure, diagnosing bugs in the API layer should become much easier compared to relying on log messages.
