These two are macros wrapping regular printf() call. They are intended
to be used instead of calling printf() directly in order to avoid
breaking TAP output format.

TAP output format is enabled by using --tap command line argument.
Starting with glib 2.62 it is enabled by default.

Unfortunately there is currently no public glib API available to check
whether TAP output format is enabled. For that reason qos_printf()
simply always prepends a '#' character for now.
