Support for (nullable) was added to G-I at the same time as nullable
return values. Previous versions of G-I will not mark return values as
nullable, even when an (allow-none) annotation is present, so it is
not necessary to add (allow-none) annotations for compatibility with
older versions of G-I.

Boxed types can't be derived from, and we don't support
deriving from our special fundamental types (the code
checks for GType equality in most places.
Currently we leak the internal representation of them as two GValues that
contain a fraction. Without this we could store fraction ranges as
data[0] = (min_n << 32) | (min_d)
data[1] = (max_n << 32) | (max_d)
and wouldn't require an additional allocation per range.
Otherwise negative values will sets all of the 64 bits due to two's
complement's definition of negative values.
Also add a test for negative int ranges.
Both gst_value_intersect and gst_value_subtract will call
gst_value_compare if one of their arguments isn't a list.
gst_value_compare will then re-do a check to see if one of
the arguments is a list (for the special case of comparing a unitary
value with a list of length 1).
The problem is that the various G_VALUE_HOLDS represent an expensive
amount of calling gst_value_compare (almost half of it) to see if
the provided arguments are list. These checks can be done without
when we know that the arguments aren't lists.
* Create a new "nolist" gst_value_compare which avoids that special
case comparision
Benchmarks:
valgrind/callgrind: average speedup in instruction calls for
gst_value_intersect and gst_value_subtract is around 56% (Makes 63%

First handle all miniobjects before we attempt to dereference the first
field pointer and look at the GType. With the recent glib change to
speed up G_IS_OBJECT, this causes crashes on miniobjects otherwise.
When a pad is added the need-parent flag is set to true, so when
they are removed the flag should be set back to false
This was preventing GstPads to be reused in elements (removed and
later re-added). A unit tests was added to verify that this is
working now.
The use case is tsdemux that has a program-number property and
allows the user to switch programs. In order to do that tsdemux
will remove the pads of the current program and add from the new
ones. The removed pads are kept in the demuxer for later if the
user selects the old program again.
Stores the last result of a gst_pad_push or a pull on the GstPad and provides
a getter and a macro to access this field.

Currently there is no other way to unlock a buffer pool other then
stopping it. This may have the effect of freeing all the buffers,
which is too heavy for a seek. This patch add a method to enter and
leave flushing state. As a convenience, flush_start/flush_stop
virtual are added so pool implementation can also unblock their own
internal poll atomically with the rest of the pool. This is fully
backward compatible with doing stop/start to actually flush the pool
(as being done in GstBaseSrc).

When we call gst_buffer_pool_set_config() the pool may return FALSE and
slightly change the parameters. This helper is useful to do the minial required
validation before accepting the modified configuration.
https://bugzilla.gnome.org/show_bug.cgi?id=727916
According to the documentation, when set_config() return false, it should be
possible to read the modified version of the config. This patch fixes the
implementation so it is now according to the documentation.

If a pool config is being configured again, check if the configuration have changed.
If not, skip that step. Finally, if the pool is active, try deactivating it.

They are very confusing for people, and more often than not
also just not very accurate. Seeing 'last reviewed: 2005' in
your docs is not very confidence-inspiring. Let's just remove
those comments.
Currently we set TAG_MEMORY as soon a resize changes the size of one
of the memory. This has the side effect that buffer pool cannot know if
the memory have simply been resized, or if the memorys has been replaced.
This make it hard to actually implement _reset(). Instead, only set the
TAG_MEMORY if one or more memory has been replaced, and do a light
sanity check of the size.

We might not have reached PAUSED yet because of an async error,
but nonetheless we want to make sure that the pads are always
deactivated in READY state.
The step can end up being zero if the underlying value isn't a valid

In those cases, return FALSE.
We don't use g_return*_if_fail since it will already have been triggered

This should allow for more meaningful errors. Dereferencing NULL
is more useful information than dereferencing a random address

We want to iterate over items idx to idx + length
We use the len variable as the corrected number of memory to iterate

Events passing through #GstPads that have a running time
offset set via gst_pad_set_offset() will get their offset
adjusted according to the pad's offset.
If the event contains any information that related to the
running time, this information will need to be updated
before usage with this offset.
GST_DEBUG_BIN_TO_DOT_FILE() would cause a segfault whenever it encountered an
element's caps that had a field value being NULL. Such fields are successfully
handled e.g. by GST_*_OBJECT(), and with this patch so does
GST_DEBUG_BIN_TO_DOT_FILE(). Even if string fields with a NULL value are
not supposed to be valid in caps, such caps can be created.

Every instance of calling bin_do_message_forward() first took the

This ensures that the lock of the internal pad is held while referencing

... instead of returning a reference to a global instance. The caller might
want to change the global instance otherwise, which causes funny effects like
all global instances being changed and at the same time nothing in the caps
being changed.
As the caps might be immutable while we do this we have to do some magic
with atomic operations.

Keep an extra write ref on the control socket. This ensures that we
avoid a read/write on the socket when going from non-empty->empty->not-empty.
We remove the write ref only when we actually are empty and we need to
wait for flushing or a new buffer.
This makes the bufferpool benchmark about 30% faster than the pure
malloc implementation.
This way we make sure that a) the lock is always taken when checking
the cookie and calling the iterator's next functions and b) it is
not taken while calling any of the iterator filter functions.

events_foreach adds an extra ref when giving the event to the
user function. In case it was unrefed by the user, this extra ref
disappeared, but events_foreach still should unref again to
lose its own ref before removing the event from the array.

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.

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,

The current documentation is controverse, while it states that the
