qemu-print: New qemu_printf(), qemu_vprintf() etc.

Browse source 
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.
