db1318ab4a pad: change the semantics of get/pull_range a little
Make it so that one can specify a buffer for get/pull_range where the downstream
element should write into. When passing NULL, upstream should allocate a buffer,
like in 0.10.
We also need to change the probes a little because before the pull probe, there
could already be a buffer passed. This then allows us to use the same PROBE
macro for before and after pulling.
While we're at the probes, make the query probe more powerful by handling the
GST_PAD_PROBE_DROP return value. Returning _DROP from a query probe will now
return TRUE upstream and will not forward the probe to the peer or handler.
Also handle _DROP for get/pull_range properly by not dispatching to the
peer/handler or by generating EOS when the probe returns DROP and no buffer.
Make filesrc handle the non-NULL buffer passed in the get_range function and
skip the allocation in that case, writing directly into the downstream provided
buffer.
Update tests because now we need to make sure to not pass a random value in the
buffer pointer to get/pull_range

d54fbe677f pad: add flag to proxy allocation query
Add a flag to force the default query handler to forward the allocation query
instead of discarding it.
Reorder the pad flags a bit.

407f45dc7f event: add STICKY_MULTY events
Add a new event flag for sticky events so that multiple events of that type can
be stored on a pad at the same time. Change the _get_sticky_event() function to
loop over the multiple events of a type.
Change the foreach function to make it possible to removed and modify the sticky
events on a pad.
Use an variable size array now to store the events. This could later be
optimized some more.

dd65aae9a1 pad: rework sticky events
Rewrite sticky events, trying to make it a bit more simple.
When sticky events are pushed on a srcpad, store them in the sticky event
array and mark the event with received = FALSE.
When the sticky event is successfully sent to the peer pad, make
received = TRUE.
Keep a PENDING_EVENTS pad flag that is set when one of the events is in
the received = FALSE state for some reason.
when activating a sinkpad, mark all events received = FALSE on the peer
srcpad.
When pushing a buffer, check the PENDING_EVENTS flag and if it is set, push all
events to the peer pad first.

2f1ed65339 pad: Merge pad mode activation functions
Add the pad mode to the activate function so that we can reuse the same function
for all activation modes. This makes the core logic smaller and allows for some
elements to make their activation code easier. It would allow us to add more
scheduling modes later without having to add more activate functions.

770159fb1c query: improve scheduling query

Make extra methods for configuring and querying the supported scheduling modes.

fe3af1d67b pad: keep the parent alive when requested

are called.

is enabled.

b5c3e254b1 pad: remove getcaps and use caps query
Remove the getcaps function on the pad and use the CAPS query for
the same effect.
Add PROXY_CAPS to the pad flags. This instructs the default caps event and query
handlers to pass on the CAPS related queries and events. This simplifies a lot
of elements that passtrough caps negotiation.
Make two utility functions to proxy caps queries and aggregate the result. Needs
to use the pad forward function instead later.
Make the _query_peer_ utility functions use the gst_pad_peer_query() function to
make sure the probes are emited properly.

24e596a1fb pad: rework pad probes
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.
