a68e33712e pad: Detect, fix and warn when sticky events are in wrong order
We can prevent buggy element from causing other elements to fail or crash
by sorting sticky event at insertion. In this case, we also warn as this
is not supposed to happen.

418dcd7277 pad: Remove SEGMENT sticky events when flushing
When flushing, it is expected that upstream will send a SEGMENT
event afterwards.

4b3aee5698 gst_pad_check_reconfigure: only remove flag if set.
the code ifed a debug statement, that can't be right. anyway, the way it is,
we don't really need that branch, as we set the flag to unset only if set
(and that can't fail) hence the end result is always to unset the flag.

d630a115f9 pad: resend dropped events
If we try to push sticky events but a probe dropped them, we don't mark
the event as received and mark the pad as PENDING_EVENTS. This ensures
that we resend the event the next time. For this we need to let the
custom flow return from the probe trickle up to
gst_pad_push_event_unchecked() so that we can differentiate between
OK and DROPPED probe returns.

one return FALSE on latency distribution causes

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

35241f35c0 pad: also push sticky events on new event
Make a helper function check_sticky to check and push pending sticky events.
Move the handling of the result of pushing the sticky event inside the
push_event function, we need to mark the event as received when it was pushed
correctly.
Move the sticky events code outside of gst_pad_push_event_unchecked and
make it purely handle sending the event to the peer.
when pushing a sticky event, first store it on the pad. Then check and push any
pending sticky events when we get a serialized or sticky event on a srcpad. This
fixes the issue where sticky events are not pushed when an event is pushed.

da74724fd5 pad: Handle sticky event errors
Use GstFlowReturn to internally pass events between pads.
When we sticky events cause an error, translate this error into a GstFlowReturn.
Caps events will, for example, generate a NOT_NEGOTIATED return when the event
function returns an error.
This allows us then to refuse sending buffers if one of the sticky events is
refused and generate a correct error return value.

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.

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".

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.

415da89f3c pad: rework pad blocking, first part
Make pad block call the callback as soon as the pad is not in use. This makes it
possible to make sure that when the callback is called, no activity is happening
on the pad and that no activity will ever happen until the pad is unblocked
again. This makes pad blocking work when there is no dataflow or after EOS and
greatly helps dynamic pipelines.
Move the probe handling right where we wait on the pad block. The two are
related but not the same and the probe can eventually influence the pad
blocking as we'll se later.
Fix up some broken unit tests or tests that fail with the new behaviour.

86c8b721b2 pad: refactor _push_event
Rework _push_event() a little so that it drops events on blocking pads.
Make sure that events are forwarded when we unblock.
Add counter on the pad to keep track of busy pads.

Refactor the code that is executed as the first step of a push operation where
we check the probes and blocking and resolve the peer.

aaba029298 pad: simplify handling of buffer lists
Implement a default buffer-list function in case the element doesn't implement
one.
Also pass buffer-lists to the have-data signal, this allows us to remove some
backward compatibility code.
