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`
If pushgin downstream returned a non-ok value (like GST_FLOW_WRONG_STATE),
we don't want to end up returning a different value (GST_FLOW_OK in this
case) if IDLE probes are present.
GstBuffer pointers can now be printed using GST_PTR_FORMAT. This is used
in the very useful GST_SCHEDULING debug logs in gstpad.c and allows for
easier and more information tracking of buffer progress through a
pipeline with just debug logging.
This allows the setcaps handler and notify::caps to link
the pad downstream and doesn't require hacks to always
provide a peer to the pad, like in decodebin2.
This reverts commit 2bfada5581.

gst/gstpad.c
For 0.11 we want to enforce that only subsets of the pad
caps are allowed. This breaks backward compatibility for
some elements, which is why we only print a warning in
0.10.
Pads should only accept caps that are a subset of the pad caps, e.g.
they should accept only caps that have a non-empty intersection and
at least all fields of the pad caps.
Without this a pad that wants for example
"video/x-h264,stream-format=byte-stream"
will be happy to accept
"video/x-h264".
Make the acceptcaps function behave like all the other functions with a default
implementation. Don't try to chain up to the default implementation when it was
set to NULL explicitly but return FALSE instead.
Fix some docs
Remove gst_pad_get_negotiated_caps(), it does not realy do what it says,
gst_pad_get_current_caps() returns the currently negotiated caps on the pad
correctly.
Refactor calling the GETCAPS function and checks.
Move the filter code in one place.
When using fixed pad caps, get the currently configured caps and then fallback
to the GETCAPS function. We used to simply ignore the GETCAPS function, which
resulted in transform elements returning the template caps instead of doing the
caps transform.
