[Help-glpk] Output streams

to make the output of my programs parsable more easily, I would like
to suppress the informational and error messages. So I propose two

glp_set_info_stream(FILE *stream);
glp_set_error_stream(FILE *stream);

or similar, where NULL means no output. (I don't think it's necessary
to have them per problem instance.)

The only tricky part is how to default these streams to stdin and
stderr, because static intitialization with stdin and stderr doesn't
work on all systems. A workaround would be to check in
glp_create_prob() whether they have already been initialized and do so
if not. (IMHO they should both default to NULL (no output), but you
seem to think otherwise :)
