9058499eeb pad: Rename and rework the dispatcher function
Rename gst_pad_dispatcher() to gst_pad_forward() and make it more useful by
iterating the internal links of a pad and handling resync properly.
Add a method gst_pad_event_forward() that unconditionally forwards an event to
all internally linked pads.
Update some pad code to use the new forward function.

3f51563319 pad: further improve probes and pad blocking
Keep track of installed number of probes to shortcut emission.
Allow NULL callbacks, this is useful for blocking probes.
Improve probe selection based on the mask, an empty mask for the data or the
scheduling flags equals that all probes match.
Add some more debug info.
Don't check the flushing flag in the probe callback handler, this needs to be
done before calling the handler.
Fix blocking probes.
Fix unit tests

fce85f75ff pad: Rework pad blocking, another attempt
Make the PadBlock callback take a GstBlockType parameter to handle the different
kind of stages in the pad block. This provides for more backwards compatibility
in the pad block API.
Separate blocking and unblocking into different methods, only blocking can do a
callback, unblock is always immediately. Also removed synchronous blocking, it
can always be implemented with a callback.

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.

one.

31a314ac5b pad: add pending event for sticky events
Change the sticky event array so that it contains a pending and an active event.
Events on the sinkpad are copied to the pending array and after the eventfunc
returned TRUE, moved to the active event. This allows us to queue new events
like when we do per-pad offsets without removing the currently active event.
Remove the active argument from the gst_pad_get_sticky_event() method, the
pending events are not something we want to expose.

e8b8c4aaa6 pad: add per-pad offsets
When linking pads and when copying a segment event from the sourc pad to the
sinkpad, apply the src and sinkpad offsets to the segment base. Make sure that
we only modify the event stored on the sinkpad and never the one on the source
pad.
When changing the pad offset, perform the segment copy with the updated offsets.
When pushing a segment event, apply the srcpad offset before sending the event
to the peer pad.
This part is missing the adjustment of the segment event on the sinkpad, which
is for a later patch.

c8340e7762 pad: add methods to adjust the offset
Add methods to adjust the offset. This will be used to change the segment events
with an offset so that we can tweak the timing of the stream on a per-pad base.

be01ecf530 pad: store sticky events on flushing sinkpads too
First store the sticky event on the sinkpad in the inactive state, then check
for the flushing flag. We want to have the events on sinkpads at all times,
ready to be activated when the pad becomes active.

500125ab4f pad: move caps check to central location
Make a function to call the eventfunc and perform a caps check when we are
dispatching a caps event.

This makes sure that all code paths correctly check that the caps are
acceptable before sending the caps to the eventfunction.

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.

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.
