Before, that was printed using --debug (and in both hb-shape and hb-view). Changed it, now hb-shape has a new command-line argument called --show-messages. When invoked, it also respects other output formatting options. The messages are better formatted and printed to te same place that hb-shape output is directed to. Previously they were written to stderr. Fixes https://github.com/behdad/harfbuzz/issues/506
