core/logging: add new logging macro nm_log_obj()

Browse source 
Add new macro nm_log_obj() to prefix the log line with a pointer value
as identifier. This macro can be used to give each logging line a common
prefix with defined format. It is mainly intended to print a message
"for" an object, for example inside a method function.
