spice_get_monotonic_time_ms() will be used more widely in the next 
patch. It may also make sense to convert some reds_get_mm_time() calls 
to spice_get_monotonic_time_ms() (e.g. in sound.c) but I'm not sure for 
these so I'm leaving that for a future patch.

An alternative would be to call g_get_monotonic_time() directly. and do 
without spice_get_monotonic_time_ms() since it's so simple, and lose the 
symmetry with spice_get_monotonic_time_ns().
