Fix the issue properly, once and for all, of how to determine

that output has taken place and suppress the printing of bindings.

* debug.c (debug): std_output replaced with std_debug.

* eval.c (eval_init): Registered new *stddebug* variable.

* stream.c (std_debug): New variable.
(stdio_put_string): Check that stream is other than
std_debug, to determine that output has taken place.

* stream.h (std_debug): Declared.

* txr.1: Added *stddebug* to documentation stub heading.
