populate SDK: prepare calling of bb.utils for exceptions
bb.utils.remove, bb.utils.movefile and bb.utils.mkdirhier can throw
exceptions that need handling and proper error messages
more work is required for these methods to handle properly the
exceptions that can be raised within the various OS calls they make
but this is a start to at least not hide the errors in the requested
operations
