We commonly want to print to the current monitor if we have one, else to stdout/stderr. For stderr, have error_printf(). For stdout, all we have is monitor_vfprintf(), which is rather unwieldy. We often print to stderr just because error_printf() is easier. New qemu_printf() and qemu_vprintf() do exactly what's needed. The next commits will put them to use.
