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.
gst_bin_query() now forwards the query to the source pads as well if
none of the sinks of the bin satisfied the query. This helps in the
case of DURATION queries done a bin containing a source element.
Fixes bug 638749
Add a GST_BIN_FLAG_NO_RESYNC that disables a resync when an element is added,
removed or linked in the bin. This is interesting for complex bins that
dynamically add elements to themselves and want to manage the state of those
elements without interference from resyncs.
See https://bugzilla.gnome.org/show_bug.cgi?id=690420
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.
Stop querying the duration once an element return unknown and return unknown
as a final result. This avoid eventually cutting off a stream too early.
Add a tests to docuement the behavior.
These changes are to clean up syntax issues such as missing colons,
missing spaces, etc., and minor issues such as argument names in
headers not matching the implementation and/or documentation.
Add the running-time of the buffer that caused the async operation to complete
to the async-done message.
Update bin to handle the new async-done message.
Make the gst_bin_remove_func more like the add_func. Check if the element we try
to remove from the bin has the bin as the parent and set the parent flag to NULL
immediately, this allows us to avoid concurrent remove operations without using
the UNPARENTING element flag. After we unparented the element from the bin, we
update the bin state and remove the element from the list. Finally we unlink
all the pads.
This avoids a race condition where the element could still claim to have the
bin as the parent while the bin didn't have a pointer to the element anymore.

When the bin does an upward state change, try to avoid doing a downward state
change on the child and vice versa.
Add some more unit tests for this fix.

There are many good use cases for GstIndex and we want
to add it back again in some form, but possibly not with
the current API, which is very powerful (maybe too powerful),
but also a bit confusing. At the very least we'd need to
make the API bindings-friendly.
