In order for a decrypter element to decrypt media protected using a
specific protection system, it first needs all the protection system
specific information necessary (E.g. information on how to acquire
the decryption keys) for that stream.
The GST_EVENT_PROTECTION defined in this commit enables this information
to be passed from elements that extract it (e.g. qtdemux, dashdemux) to
elements that use it (E.g. a decrypter element).

This specifies if a given taglist applies to the complete
medium or only this specific stream. By default a taglist
has a stream scope.
Fixes bug #677619.
Make it possible to wrap all kinds of memory by exposing all properties to
gst_buffer_new_wrapped_full(). This makes it possible to also create writable
memory without a free function or memory with extra padding.
Make a new GstPadProbeInfo structure and pass this in the probe callback. This
allows us to add more things later and also allow the callback to replace or
modify the passed object.
Make a separate cookie to detect chancges in the list of probes and keeping
track of what hooks have been invoked yet.
Remove the requirement to have probes on srcpads in push mode and sinkpads in
pull mode.
Add some more debug.
Keep track of what callbacks got executed. If no callback is called and we are a
blocking pad, let the item pass. This allows you to block pads on selected
items only.
Explicitly have an UPSTREAM and DOWNSTREAM PadProbeType. This allows you to only
block the pad on upstream or downstream items.
Add convenience macros to only block on downstream/upstream items.
Better now than later in the cycle. These might come in handy:
sed -i -e 's/GstProbeReturn/GstPadProbeReturn/g' `git grep GstProbeReturn | sed -e 's/:.*//' | sort -u`
sed -i -e 's/GST_PROBE_/GST_PAD_PROBE_/g' `git grep GST_PROBE_ | sed -e 's/:.*//' | sort -u`
sed -i -e 's/GstProbeType/GstPadProbeType/g' `git grep GstProbeType | sed -e 's/:.*//' | sort -u`
Add a boolean to the flush_stop event to make it possible to implement flushes
that don't reset_time.
Make basesink post async_done with the reset_time property from the flush stop
event.
Fix some unit tests
Keep track of installed number of probes to shortcut emission.
Allow NULL callbacks, this is useful for blocking probes.
Improve probe selection based on the mask, an empty mask for the data or the
scheduling flags equals that all probes match.
Add some more debug info.
Don't check the flushing flag in the probe callback handler, this needs to be
done before calling the handler.
Fix blocking probes.
Fix unit tests
Make the PadBlock callback take a GstBlockType parameter to handle the different
kind of stages in the pad block. This provides for more backwards compatibility
in the pad block API.
Separate blocking and unblocking into different methods, only blocking can do a
callback, unblock is always immediately. Also removed synchronous blocking, it
can always be implemented with a callback.
Improve GstSegment, rename some fields. The idea is to have the GstSegment
structure represent the timing structure of the buffers as they are generated by
the source or demuxer element.
gst_segment_set_seek() -> gst_segment_do_seek()
Rename the NEWSEGMENT event to SEGMENT.
Make parsing of the SEGMENT event into a GstSegment structure.
Pass a GstSegment structure when making a new SEGMENT event. This allows us to
pass the timing info directly to the next element. No accumulation is needed in
the receiving element, all the info is inside the element.
Remove gst_segment_set_newsegment(): This function as used to accumulate
segments received from upstream, which is now not needed anymore because the
segment event contains the complete timing information.

* docs/gst/gstreamer-sections.txt:
* gst/gstevent.c: (gst_event_has_name):
* gst/gstevent.h:
* tests/check/gst/gstevent.c: (GST_START_TEST):
Add method to conveniently check the name of a custom event with
gst_event_has_name().
Reformat the event docs so that related methods are put together instead
of the default alphabetical sort.
Update unit test with new method.

* gst/gstevent.c: (_gst_event_copy):
Fix gst_mini_object_make_writable() and gst_event_copy() for events
with event structures by setting the parent refcount address of the
copied structure to the address of the refcount member of the newly
copied event rather than the address of the refcount member of the
original event. Fixes#358737.
* tests/check/gst/gstevent.c: (GST_START_TEST):
Unit test for the above.
Original commit message from CVS:
* gst/gstelementfactory.c: (gst_element_factory_create):
Remove unnecessary ref/unref pair
* gst/parse/grammar.y:
Make sure to free the parse buffer on all code paths.
Move a g_free up to the error handler where it's easier to see.
* tests/check/gst/gstevent.c: (test_event):
Extending timeout for downstream travelling events to 10 seconds to
hopefully avoid intermittent failure on the buildbots.
* tests/check/pipelines/parse-launch.c: (run_delayed_test):
Don't manually set the state of the src element - it will happen as a
natural consequence of the pipeline changing state, and that way it
will do it in the right order too.
Original commit message from CVS:
* gst/gstpad.c: (handle_pad_block), (gst_pad_push_event):
Implement pad blocking on events according to part-block.txt.
More comments on behaviour.
* tests/check/gst/gstevent.c: (test_event):
Send event to peer pad of blocked pad (else it will block).
