When holding a regular ref it will cause the GstBus to never
reach 0 references and it won't be destroyed unless the application
explicitly calls gst_bus_remove_signal_watch().
Switching to weakref will allow the GstBus to be destroyed.
The application is still responsible for destroying the
GSource.

ghostpad: Do nothing in _internal_activate_push_default
Fixes a race where an entry is set to BUSY in
gst_system_clock_id_wait_jitter() and is UNSCHEDULED before
gst_system_clock_id_wait_jitter_unlocked() starts processing it. The
wakeup added by gst_system_clock_id_unschedule() must be cleaned up.
Two stress tests are added. One test that triggers the specific issue
described above. The second stresses the code path where a wait is
rescheduled because the poll returned early.

Change the gst_tracer_record_new() api to take the parameters the make the
spec structure directly. This allows us to own the top-level structure and
also collect the args so that we can take ownership of the sub-structures.
https://bugzilla.gnome.org/show_bug.cgi?id=760821
We use this class to register tracer log entry metadata and build a log
template. With the log template we can serialize log data very efficiently.
This also simplifies the logging code, since that is now a simple varargs
function that is not exposing the implementation details.
Add docs for the new class and basic tests.
Remove the previous log handler.
Fixes#760267
Adds 3 new tests for testing accept-caps behavior with
proxy-caps pads.
1) A scenario where there is no proxy. The caps should be compared to the
template caps of the pad
2) A scenario where there is a compatible pad. The caps should be compared
to the proxied pad caps (and also with the template)
3) A scenario where there is an incompatible proxy pad. No caps should be
possible at all.

Updated gst_segment_position_from_stream_time and gst_segment_to_stream_time to reflect correct calculations for the case when the applied rate is negative.
Pasting from design docs:
===============================
Stream time is calculated using the buffer times and the preceding SEGMENT
event as follows:
stream_time = (B.timestamp - S.start) * ABS (S.applied_rate) + S.time
For negative rates, B.timestamp will go backwards from S.stop to S.start,
making the stream time go backwards.
===============================
Therefore, the calculation for applied_rate < 0 should be:
stream_time = (S.stop - B.timestamp) * ABS (S.applied_rate) + S.time
and the reverse:
B.timestamp = S.stop - (stream_time - S.time) / ABS (S.applied_rate)
https://bugzilla.gnome.org/show_bug.cgi?id=756810
The previous change (see bgo #756069) was causing us to free the same pointer
multiple times. If we actually get a sample back, the test fails, no need to
free anything in that case.
When adding an element to a bin we need to propagate the GstContext's
to/from the element.
This moves the GstContext list from GstBin to GstElement and adds
convenience functions to get the currently set list of GstContext's.
This does not deal with the collection of GstContext's propagated
using GST_CONTEXT_QUERY. Element subclasses are advised to call
gst_element_set_context if they need to propagate GstContext's
received from the context query.
https://bugzilla.gnome.org/show_bug.cgi?id=705579
gst_segment_to_position might cause confusion, especially with the addition of
gst_segment_position_from_stream_time . Deprecated gst_segment_to_position
now, and replaced it with gst_segment_position_from_running_time.
Also added unit tests.
In some cases, probes might want to handle the buffer/event/query
themselves and stop the data from travelling further downstream.
While this was somewhat possible with buffer/events and using
GST_PROBE_DROP, it was not applicable to queries, and would result
in the query failing.
With this new GST_PROBE_HANDLED value, the buffer/event/query will
be considered as successfully handled, will not be pushed further
and the appropriate return value (TRUE or GST_FLOW_OK) will be returned
This also allows probes to return a non-default GstFlowReturn when dealing
with buffer push. This can be done by setting the
GST_PAD_PROBE_INFO_FLOW_RETURN() field accordingly

If no date and only a time is given in gst_date_time_new_from_iso8601_string(),
assume that it is "today" and try to parse the time-only string. "Today" is
assumed to be in the timezone provided by the user (if any), otherwise Z -
just like the behavior of the existing code.

The check for the presence of the parent in the presence of
the NEED_PARENT flag was missing for the chain function. Also keep
a ref on the parent in case the pad is removed mid-chain.
test_intersect_flagset fails because when caps is being
created, flags and mask are being cast to uint64 while
they should be uint. This results in invalid memory access
or a segfault.

Adds tests for gst_element_get_compatible_pad for when it has to
request pads.
Note that these tests don't cover the case when it has to request
a pad that already exists.

gst/gstmemory.c:570:38: error: implicit conversion from enumeration type 'GstMapFlags' to different enumeration
type 'GstLockFlags' [-Werror,-Wenum-conversion]
fail_unless (gst_memory_lock (mem, GST_MAP_WRITE));
~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~
Now that locking exclusively dows not always succeed, we need to signal
the failure case from gst_memory_init.
Rather than introducing an API or funcionality change to gst_memory_init,
workaround by checking exclusivity in the calling code.
https://bugzilla.gnome.org/show_bug.cgi?id=750172
gst_memory_lock (mem, WRITE | EXCLUSIVE);
gst_memory_lock (mem, WRITE | EXCLUSIVE);
Succeeds when the part-miniobject.txt design doc suggests that this should fail:
"A gst_mini_object_lock() can fail when a WRITE lock is requested and
the exclusive counter is > 1. Indeed a GstMiniObject object with an
exclusive counter 1 is locked EXCLUSIVELY by at least 2 objects and is
therefore not writable."
