* gst/gstclock.h (GstClock): Add rate and offset properties,
preserving ABI stability. Add rate/offset accessors. Will file bug
for the freeze break.

* gst/gstclock.c (gst_clock_adjust_unlocked): Implement using rate
and offset, trying to keep precision and avoiding
underflow/overflow.
(gst_clock_set_rate_offset, gst_clock_get_rate_offset): New
functions. Make gst_clock_set_time_adjust obsolete.
(gst_clock_set_time_adjust): Note that this function is obsolete.
Will file bug soon.

* gst/base/gstbasetransform.h: Make the ABI-stability hack
greppable by using GST_PADDING-1+1.
