* gst/net/gstnetclientclock.c (do_linear_regression): Use all
integer arithmetic. Return the minimum of the domain, which can be
set as "internal" for gst_clock_set_calibration.
(gst_net_client_clock_observe_times): Call _set_calibration.
(gst_net_client_clock_new): Call _set_calibration instead of
rate_offset.

* check/net/gstnetclientclock.c (test_functioning): Use the right
adjustment api.

* gst/gstclock.h:
* gst/gstclock.c (gst_clock_get_calibration)
(gst_clock_set_calibration): New functions, obsolete the ones I
added yesterday. Doh. Precision issues mean we have to extrapolate
from a point in the more recent past than 1970.
(gst_clock_get_rate_offset, gst_clock_set_rate_offset): Mark as
obsolete.
(gst_clock_adjust_unlocked): Use the right calibration data.
