Make this work again:
audiotestsrc ! tee name=t t.src_0 ! queue ! fakesink t.src_1 ! queue ! fakesink
and this fail again:
audiotestsrc ! tee name=t t.src_1 ! queue ! fakesink t.src_0 ! queue ! fakesink
as tee just counts itself and does not care about the pad names we request
from it.
This allows blocking a pad, add a new blocking probe, removing
the first probe and then having the second probe called. Which
could then decide that data-flow should actually continue
instead of blocking now.
https://bugzilla.gnome.org/show_bug.cgi?id=721289
Also only check the data types for non-IDLE probes. When we
are idle, we have no data type obviously.
Previously we were calling IDLE probes during data flow whenever
a non-blocking probe would be called. The pad was usually not idle
at that time.
Checking twice the lower bound is great (you never know, it might change
between the two calls by someone using emacs butterfly-mode), but it's a bit
more useful to check the higher bound are also identical.

codec parsers) caused by commit ccba9130.

Make a new flag on the pad that tweaks the default behaviour of the
accept-caps function. By default it will check for a subset of the
query-caps result but this is not always desirable. The query-caps
result contains all the constraints to make a good caps decision
upstream but sometimes, like for parsers, not all the constrained caps
fields are known upstream and then a subset check would fail. Switching
to an intersection makes this work again.

Older versions of flex (before 2.5.36) don't add the prototype, so it must
be added manually. We can't check by the version number, because Debian/Ubuntu
patched it into their 2.5.35 at some point.
This reverts commit 8162a583a4.
Automatically copying the sticky events makes it impossible for apps
and elements to filter the events with event probes. This causes
regressions (See #719437). The best option is to let the app/element
copy and filter the events themselves after the ghostpad target is
set.
Update the sticky events on SRC ghostpads when retargeting. This ensures
that the ghostpad has the exect same sticky events as the target pad. We
don't want to do this for SINK ghostpads, they got the events from
downstream and we don't want to overwrite them with the target pad
events.

It was unintuitive that GstContext was actually a list of different
contexts. GstContext now is only a type string and a structure to
contain the actual context.
Non-persistent contexts are removed when elements go back
to NULL state, persistent contexts are not. Applications
most likely want to set persistent contexts.
Since the default number of max unused threads in GThreadPool has been
changed from 0 to 2 it needs to be set to 0 to stop all threads or
valgrind will report them as memory leaks.
This makes gst_parse_bin_from_description() return an element instead of
a bin if there's only one element. Also changed gstparse.c to use this,
so gst-launch won't create superfluous bins.

The current documentation is controverse, while it states that the
returned value is valid only while the query is is valid, which presumes
a 'transfer none' policy. But the tooltip for the 'out' annotation
states the default is 'transfer-full'.
Add the missing 'transfer none' annotations to fix this.
Tweak the documentation slightly to clarify that the estimated-total in

If all stream-start messages had a group id (for backwards compatibility),
we only consider a stream started if all had the same group id.
In 2.0 we should make the group id mandatory.
All streams that have the same group id are supposed to be played
together, i.e. all streams inside a container file should have the
same group id but different stream ids. The group id should change
each time the stream is started, resulting in different group ids
each time a file is played for example.
This makes sure that no bin misses the clock-lost messages, independent
of the state, and could return an old, non-working clock from
gst_bin_provide_clock_func().

Renegotiation and reconfiguration will fail because all queries
and events won't be accepted by the pad if it's flushing. In the
best case this just causes unneeded work and spurious warnings in
the debug logs, in the worst case it causes elements to fail completely.
When appending/prepending tags, avoid re-creating (and copying) lists if we already
have one and instead just append/prepend the GValue to the list.

API: gst_value_array_append_and_take_value
API: gst_value_list_append_and_take_value
We were already using this internally, this makes it public for code
which frequently appends values which are expensive to copy (like
structures, arrays, caps, ...).
Avoids copies of the values for users. The passed GValue will also
be 0-memset'ed for re-use.
New users can replace this kind of code:
gst_value_*_append_value(mycontainer, &myvalue);
g_value_unset(&myvalue);
by:
gst_value_*_append_and_take_value(mycontainer, &myvalue);

But do this only for events that are not dropped by flushing,
i.e. do it only for everything except SEGMENT and EOS.
Without this we might drop a CAPS event if flushing happens
at an unfortunate time and nobody is resending the CAPS event.
https://bugzilla.gnome.org/show_bug.cgi?id=700806
If a pad block was triggered from sending a sticky event downstream, it
could happen that the pad block is relinking pads, which then requires
to resend previous sticky events.
Previous patch was inforcing a complete ordering of the sticky events, while
in fact, only STREAM_START, CAPS and SEGMENT events need proper ordering.
See: https://bugzilla.gnome.org/show_bug.cgi?id=688188
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.

Fixes abort when the old specifiers are used. Fix up the conversion
specifier, it would get overwritten with 'c' below to the extension

API: GST_PLUGIN_STATIC_DECLARE()
API: GST_PLUGIN_STATIC_REGISTER()
Based on a patch by Håvard Graff <havard.graff@tandberg.com>.
This now allows GST_PLUGIN_DEFINE() to create a static plugin if
GST_PLUGIN_BUILD_STATIC is defined. The resulting plugin can be
statically linked or dynamically linked during compilation but
can't be dynamically loaded during runtime.
Also adds GST_PLUGIN_STATIC_DECLARE() and GST_PLUGIN_STATIC_REGISTER(),
which allows to register a static linked plugin easily.
It is still required to manually register every single statically linked
plugin from inside the application as this can't be automated in a portable
way.
A new configure parameter --enable-static-plugins was added that allows
to build all plugins we build here as static plugins.
Fixes bug #667305.
The gst_plugin_feature_rank_compare_func() should return
negative value, if the rank of both PluginFeatures are equal and
the name of first PluginFeature comes before the second one.

Don't use snprintf(), but use sprintf instead and do our own
length calculations, because glibc may complain about us passing
%n in a format string if the string is in writable memory, and
here the format string is always in writable memory since we
construct it on the fly. This happens if glibc has been compiled
with _FORTIFY_SOURCE=2, which seems to be the case on some
distros/systems). On the upside, we now use the sprintf code path
on all systems which should be better from a maintenance point
of view.

Iterate over the fields of the superset instead of those of the subset.
This way we can check the presence of the subset field and do the subset check
in one iteration.
Very often, when the end of a segment is detected by demuxer, the position
is slightly outside the segment boundaries. Currently, if that is the case
the base will be set to NONE instead of normal accumulation. This would
break non-flushing seeks in oggdemux and most likely other demuxers.

This is equal to any other caps features but results in unfixed caps. It
would be used by elements that only look at the buffer metadata or are
currently working in passthrough mode, and as such don't care about any
specific features.
