c41b0ade28 bus: Use a construct-only property to distinguish between child buses and normal buses
This allows to only create the socketpair when it is really required instead
of always creating it and immediately destroying it again for child buses.

874d60e589 bus: Add private API to set a GstBus in child mode
This is used by GstBin to create a child bus without
a socketpair because child buses will always work
synchronous. Otherwise too many sockets could be
created and the limit of file descriptors for the
process could be reached.

Fixes bug #646624.

bae67f116c basesrc: Return FALSE if we don't handle an event
basesrc's default event handler returns TRUE regardless of whether the
event is handled or not. This fixes the handler to conform with the
expected behaviour (which is to only return TRUE when the event has
actually benn handled). gst_bin_do_latency_func() depended on this
(incorrect) behaviour, and is now modified as well.

(Remaining 1-liner change in gstbasesrc.c is to keep gst-indent happy)

27c6aba33c bin: Improve tracking of source elements
Track elements tagged with the IS_SOURCE flag in a similar way we track the sink

a9a82da134 bin: add message-forward option
Add an option to forward all the internal messages that would otherwise be
filtered such as EOS, SEGMENT and ASYNC messages.
This allows the application to, for example, detect that a partial pipeline is
prerolled or reached eos.
The original messages are wrapped inside an element message because the parent
bins are not supposed to see those internal messages escape.

57cc780c45 bin: relax the source element check
When there is a sink inside a bin, the SINK flag is set on the bin. When we are
trying to iterate the source elements, also include the bins with the SINK flag
because they could also contain source elements, in which case they are also a
source.

This solves the case where sending an EOS to a pipeline didn't get dispatched to
all source elements.

71f3a6f0f7 Don't include <libxml/parser.h> from public headers if GST_DISABLE_DEPRECATED is defined

defined.

5f4a965f67 gstxml: Deprecate GstXml and related functions
Pipeline serialisation to and from XML is horribly broken for all

this, to avoid frustration. See countless bug reports in bugzilla.

da287f556d parse-launch: make delayed set recursive
Right now deleyed set would only try for first set of children. We need to keep
trying to support arbitrary deep hierarchies (like in playbin2 with auto*sinks).
Also GstBin would need to actualy emit the child-added/removed signal as it
implements the iface. Fixes #613215.

f44d8c31de bin: never skip a state change to PLAYING
Never skip the state change to playing, even if the element is already in the
right state. We need this because we also distribute the base_time while doing
the state change and skipping this step would leave some elements without a new
base_time.

daecaf0e8a Remove GST_DEBUG_FUNCPTR where they're pointless
There's not much point in using GST_DEBUG_FUNCPTR with GObject
virtual functions such as get_property, set_propery, finalize and
dispose, since they'll never be used by anyone anyway. Saves a
few bytes and possibly a tenth of a polar bear.

f64243e037 states: post structure change on sinkpads
Post the structure change messages on the sinkpads of the elements. This allows

1ab11faf48 bin: avoid false 'loop detected' warnings
When we detect a pad unlink in progress, we will not be updating the degree of
the parent element. This can cause false loop detected warnings because the
degree counter is invalid. Handle this case by marking the iterator as 'dirty'
when we detect a pad unlink and avoid emiting the warning in this case. We have
to continue our state change as good as we can, we will eventually resync when
the pad unlink completed.

1b4b1a5b1f bin: always mark pending_async_done
When we get an ASYNC_DONE message when a state change was busy, set the
pending_async_done flag so that after the state change completes, the bin can
check if all async elements are finished. Don't only do this for the bin itself
but for all elements.

This fixes some bins in bins that simulate async state changes by posting ASYNC
messages (such as sdpparse in uridecodebin/playbin2).

b3e56e19f5 bin: forward segment-start like segment-done if parent is also a bin, fixes #575598.
Bin collects segment-start messages and segent-done messages. it posts a
segment-done message to its parent, once it has received a segment-done for
each segment-start. Imho it should also send a segment-start if it receives the
first segment start and if parent is !=NULL. This is needed for bins in bins,
so that also higher order bins can group segment-starts and segment-dones.
Right now higher order bins will post a segment-done for each segment-done
received.
