DDB_ONPANIC. Lets user ignore breaks but enter DDB on panic. Intended for machines where debug on panic is useful, but DDB entry is not, (public-access console, or terminal-servers which send spurious breaks) Add new ddb hook, console_debugger(), which decides whether or not to ignore console ddb requests. Console drivers should be updated to call console_debugger(), not Debugger(), in response to serial-console break or ddb keyboard sequence.
