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.

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.

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.

60fba4df8b gstpad: Fix flush-stop event handling
A flush-stop event would make a pad unflushing, causing it
to start acting as an activated pad. This, for example,
could lead to the chain function being called when stuff
isn't initialized.

This could happend when setting qtdemux to NULL while a seek
was being handled in the upstream filesrc (in push mode).

This patch makes it check if it is activated before setting
it to unflushing.

7fa58dbebd GstPad: Do not call gst_pad_accept_caps() when caps change
Instead just check that the caps intersect with the pad template.
The elements should properly accept/refuse the caps in setcaps().

Shaves off calling the default implementation of acceptcaps which does
an expensive gst_pad_get_caps() (so if you have 50 of those elements in
a row, you'd be doing factorial(50) gst_pad_get_caps...).

Does not break any module unit test and most apps work fine.

381d35fd1e pad: Fix problem with destroy callback not being called
When we unblock a pad with the same user_data, the destroy callback is not

In particular, this fixes a nasty pad leak in decodebin2.

746284f807 pad: make _fixate_caps() also truncate when needed
The default gst_pad_fixate_caps() previously would only fixate each individual
struct. In case there are multiple structs, the resulting caps would still not
be fixed. In the spirit of how individual structs are fixated, this patch
changes gst_pad_fixate_caps() to remove all but the first struct.
