We dont't want to depend on GLib 2.34 for now.

We were writing unitialized stack memory to the file.

Just show all devices then.

Each filter will include a GstCaps and a set of classes to match

Other languages have their own data structures that are more convenient to
use.

gst_mini_object_replace() can take NULL mini-objects.

It does not make sense for them.

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.

And remove some which don't apply any more.

Compliments my previous patch for gst_caps_set_features, which would
previously assert and leak the old GstCapsFeatures if the caps already
had a GstCapsFeatures and you were trying to replace it with a new one.

Otherwise gst_caps_features_free() asserts and the features structure is leaked

When the parser receives non-aligned packets it can push a buffer
and get a not-linked return while still leaving some data still to
be parsed. This remaining data will not form a complete frame and
the subclass likely returns _OK and baseparse would take that
as the return, while it the element is actually not-linked.

This patch fixes this by storing the last flow-return from a push
and using that if a parsing operation doesn't result in data being
flushed or skipped.

Trivial as it may be, this code was mostly copied from
somewhere else. The gtk-doc chunk is not needed, since
it's not public API.

This make it works with FIFOs.

Not some flag value instead of TRUE. Fixes code like
gst_caps_is_any() == TRUE.

There's some precedent in GstElementFactory, but a
"klass" property just seems weird.

And default to 50 loops.

Calling GST_VALUE_HOLDS_*(&v) now results in a compiler
warning about value!=NULL always being false, so check
type directly in those cases.

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.
