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

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

elements to make their activation code easier. It would allow us to add more
scheduling modes later without having to add more activate functions.

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.

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.

d8212d941c pad: forward events by default
Always forward all events in the default handler. Previously it used to not
forward caps events by default. It makes more sense to forward the caps events,
if the element is interested in the caps, it will implement an event handler to
retrieve the caps and then it can decide to forward or not. If the element has
no event handler, it probably just doesn't care about caps and it probably is
also not going to modify the data in a way that needs a caps change.

3d2127f865 Revert "query: allow _make_writable on query handlers"
This reverts commit cf4fbc005c.

This change did not improve the situation for bindings because
queries are usually created, then directly passed to a function
and not stored elsewhere, and the writability problem with
miniobjects usually happens with buffers or caps instead.

c4751ec8c1 Revert "context: use context on buffers instead of caps"
This reverts commit 9ef1346b1f.

Way to much for one commit and I'm not sure we want to get rid of the pad caps
just like that. It's nice to have the buffer and its type in onw nice bundle
without having to drag the complete context with it.

9ef1346b1f context: use context on buffers instead of caps
Put the srcpad context on buffers instead of caps. This allows us to associate
all the relevant info contained in events with a buffer.

bc9cffda90 pad: more sticky events work
Copy the sticky events from the srcpad to the sinkpad when linking pads. Set the
STICKY_PENDING flag to make sure that the sticky events are dispatched before
pushing the next buffer to the element.

2243adffa1 event: add sticky flags to events
Add the sticky flag to events and a sticky index.
Keep sticky events in an array on each pad.
Remove GST_EVENT_SRC(), it is causing refcycles with sticky events, was not used
and is not very interesting anyway.

6ab7e6c15d Remove pad_alloc, this can now be done better
Remove pad_alloc and all references. This can now be done more efficiently and
more flexible with the ALLOCATION query and the bufferpool objects. There is no
reverse negotiation yet but that will be done with an event later.
