gst_clock_wait_for_sync(), gst_clock_is_synced() and gst_clock_set_synced()
plus a signal to asynchronously wait for the clock to be synced.
This can be used by clocks to signal that they need initial synchronization
before they can report any time, and that this synchronization can also get
completely lost at some point. Network clocks, like the GStreamer
netclientclock, NTP or PTP clocks are examples for clocks where this is useful
to have as they can't report any time at all before they're synced.

gst_clock_add_observation_unapplied() adds a new master/slave clock
observation and runs the regression without activating the new
calibration results.
gst_clock_adjust_with_calibration() uses directly passed calibration
parameters, instead of using the clock's current calibration,
allowing for calculations using pending or old calibration params
Move the controller to gstobject as a simple delegate. The controller and
controlsource are not classes in core. The controlsources stay separate as a lib
for now. This way we can avoid the qdata lookups.
Also remove controller_init(). There is no more need to link to controller for
elements.
Also sanitize the API. We now have functions to add properties like we had
methods to remove that. That avoids then ref count hacks we had in _new.
gobject-introspection won't parse them properly otherwise.
Still need to force the right type though (either GstClockTime or
guint64), but Type: xyz has no effect for me here, so someone with
a newer g-i needs to test this.
Some other defines are also missing, e.g. GST_CLOCK_TIME_NONE.
The padding of GstClock is a GstClockTime and not a
gpointer, so adding a pointer requires the padding
size to be changed depending on the pointer size.
Use an union instead.
Fixes bug #582878.

Start merging in the easy bits of #361155, the monotonic clock patch.
This one adds a few handy macros with docs and a testsuite.

internal time based on calibration.
Add some more debug.

Fix a possible segfault when the window-size is made smaller.
Calculate jitter before performing the clock wait. Ideally
the clock implementation should calculate jitter but we need

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.

Implement master/slave. When setting a clock as a slave, a

Then the slave clock is recalibrated to match offset and rate
of the master clock.
Update logging a bit.
Add flag so that a clock can state that is cannot be slaved to
another clock.
