bffc9207b5 pad: rename GstProbeType and GstProbeReturn to GstPadProbe{Type,Return}
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`

029ac4597e pad: rework sticky events a little
Update the design docs with some clear rules for how sticky events are
handled.
Reimplement the sticky tags, use a small structure to hold the event and its
current state (active or inactive).
Events on sinkpads only become active when the event function returned success
for the event.
When linking, only update events that are different.
Avoid making a copy of the event array, use the object lock to protect the event
array and release it only to call the event function. This will need to check
if something changed, later.
Disable a test in the unit test, it can't work yet.
