Andy Wingo da72aaa235 check/net/gstnetclientclock.c (test_functioning): Adjust to rate_num/rate_denom change.
Original commit message from CVS:
2005-11-23  Andy Wingo  <wingo@pobox.com>

* check/net/gstnetclientclock.c (test_functioning): Adjust to
rate_num/rate_denom change.

* gst/net/gstnetclientclock.c
(gst_net_client_clock_observe_times): Take the SLAVE_LOCK not the
OBJECT_LOCK. Don't call add_observation with the lock.

* gst/gstclock.c (gst_clock_init): Initialize the rate as a
fraction.
(gst_clock_adjust_unlocked): Adjust using uint64_scale and the
rate fraction.
(gst_clock_set_calibration, gst_clock_get_calibration): Change to
deal with rate as a fraction whose numerator and denominator are
GstClockTime values.
(gst_clock_set_master): Only use the OBJECT_LOCK to set the
master; the other fields are protected by the SLAVE_LOCK.
(do_linear_regression): Note that this must be called with the
SLAVE_LOCK.
(gst_clock_add_observation): Take the SLAVE_LOCK, not the
OBJECT_LOCK. Call set_calibration instead of touching the
variables directly.
(gst_clock_set_property, gst_clock_get_property): Protect
master/slave parameters with the SLAVE_LOCK.

* gst/gstclock.h (GstClock): Remove rate, add rate_numerator and
rate_denominator. PR3C1S3. Add a new lock, the SLAVE_LOCK, and
note that all of the instance variables that add_observation and
the set_master functions use are protected by that lock and not
the OBJECT_LOCK.
(GST_CLOCK_SLAVE_LOCK, GST_CLOCK_SLAVE_UNLOCK): New macros.

* gst/gstclock.c (gst_clock_add_observation): No longer requires
the caller to take the object lock.
