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);

This function works just like gst_data_queue_pop, but it doesn't
remove the object from the queue.
Useful when inspecting multiple GstDataQueues to decide from which
to pop the element from.
Add: gst_data_queue_peek
Source elements with limited bandwidth capabilities and supporting
buffering for downstream elements should set this flag when answering
a scheduling query. This is useful for the on-disk buffering scenario
of uridecodebin to avoid checking the URI protocol against a list of
hardcoded protocols.

These are meant to specify features in caps that are required
for a specific structure, for example a specific memory type
or meta.
Semantically they could be though of as an extension of the media
type name of the structures and are handled exactly like that.
Elements should override GstElement::set_context() and also call
gst_element_set_context() to keep this context up-to-date with
the very latest context they internally use.
The duration should be re-queried via a query using the
normal path, we don't want applications to use the value
from the message itself, since it might no match what a
duration query done from the sink upstream might yield.
Also disables duration caching in GstBin. It should be
added back again at some point.
Not so useful: just adds/reads stuff from an internal GList without
actually doing anything with those paths, so remove for now:
gst_registry_add_path
gst_registry_get_path_list

Add an alternative version of gst_pad_check_reconfigure that doesn't
clear the reconfigure flag.
Useful for increasing error resilience without duplicating the
reconfigure code in pad task functions.

This is because we need to be able to signal different TOCs
to downstream elements such as muxers and the application,
and because we need to send both types as events (because
the sink should post the TOC messages for the app in the
end, just like tag messages are now posted by the sinks),
and hence need to make TOC events multi-sticky.
