The previous log handler wasn't actually hooked up to anything. Add a public API for the log handler with priority filtering, defaulting to priority 'error' and stderr as output stream. And to keep the diff down and convenience up, provide a few simple wrappers for logging. The generic is log_msg(), but let's use log_info, log_error, etc. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Reviewed-by: Jonas Ådahl <jadahl@gmail.com>
