Converts the given external clock time to the internal time of clock,
using the rate and reference time set with gst_clock_set_calibration().
This function should be called with the clock's OBJECT_LOCK held and
is mainly used by clock subclasses.
This function is the reverse of gst_clock_adjust_unlocked().
