Macro for logging

By default, the logging macros emit the given messages with its formatted parameters and add the file path, the line number within the file and the function name locating from where the macro comes.

However, the final behaviour of macros can be tuned using 2 preprocessor defines that can be defined before including <afb/afb-binding.h>:

• AFB_BINDING_PRAGMA_NO_VERBOSE_DATA: if defined, only filename and line are shown
• AFB_BINDING_PRAGMA_NO_VERBOSE_DETAILS: if defined, only the message and its formatted arguments are shown
