util: _debug_printf should print even when DEBUG is not defined

The leading underscore is meaningful...  This function is used by
_warning and _error functions as well as the more common
debug_printf().

debug_printf (without underscore) gets turned off when DEBUG is
disabled, but warning/error messages still use this function to get
their message out.
