        * defs.h (fatal, vfatal): New function prototypes.
        * stack.c (backtrace_command_stub): Stub to call backtrace_command_1
        via catch_errors.
        (backtrace_command): Change to call backtrace_command_stub via
        catch_errors instead of calling backtrace_command_1 directly.
        (backtrace_full_command): Ditto.
        * utils.c (error_stream_1): New static function.
        (verror): Change to call error_stream_1 instead of error_stream.
        (error_stream): Call error_stream_1 with RETURN_ERROR argument.
        (vfatal, fatal): New functions.
