Berthold Stoeger 5da09a21bb Cleanup: move error reporting function declarations to errorhelper.h 
Move the declarations of the "report_error()" and "set_error_cb()"
functions and the "verbose" variable to errorhelper.h.
Thus, error-reporting translation units don't have to import the
big dive.h header file.
