Since we started depending on GLib 2.44, we can be sure this macro is
defined (it will be a no-op on compilers that don't support it). For
plugins we should just start using `G_DECLARE_FINAL_TYPE` which means
we no longer need the macro there, but for most types in core we don't
want to break ABI, which means it's better to just keep it like it is
(and use the `#ifdef` instead).
GST_TIME_FORMAT, GST_TIME_ARGS, GST_STIME_FORMAT, GST_STIME_ARGS
GST_PTR_FORMAT, GST_SEGMENT_FORMAT, GST_FOURCC_FORMAT and
GST_FOURCC_ARGS are format specifiers.
They can't be used outside of C and should be generated in the gir.

We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.
They were (signed!) gint64 before because of G_GINT64_CONSTANT() already
and they are actually used in signed calculations.
With this change we at least ensure that an integer type of the correct
size is used for GI (it was using gint before).
This macro didn't work well as it relied on the sign on the last
divided number (number of days). This value is most of the time
zero, and zero is considered positive in printf. Instead, deal with
the sign manually, and resuse the original macros for the rest. This
actually simplify the macro a lot.
There was few Since: mark missing their column. Also unify the way
we set the Since mark on enum value and structure members. These
sadly don't show up in the index.
Add utility to print signed value of time. This is useful to
trace running time values in gint64 or GstClockTimeDiff values.
Additionally, define GST_CLOCK_STIME_NONE to indicate an invalid
signed time value and validation macro. New macros are:
GST_CLOCK_STIME_NONE
GST_CLOCK_STIME_IS_VALID
GST_STIME_FORMAT
GST_STIME_ARGS

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.
