abe60a92c4 funnel: Make sure to only lock the stream lock once
We also only unlock it once, and otherwise have it locked forever from
this thread, causing deadlocks on shutdown later.

c56e1d18c1 funnel: Always push all sticky events whenever we forward a serialized event
Otherwise downstream will have an inconsistent set of sticky events at this
point, e.g. when a TAG event is pushed and downstream wants to relate it to
the stream by looking at the current STREAM_START event.

528fbfe7c1 funnel: Only forward sticky events on GAP events if needed
That is, if the active pad changed and if forwarding of sticky events is
requested at all. We otherwise forward events too often.

2c60b7eb1f funnel: Fix racy state change
Iterator may need to be resynced, for instance if pads are released
during state change.

got_eos should be protected by the object lock of the element, not of
the pad, as is the case throughout the rest of the funnel code.

154eefecc9 Don't compare booleans for equality to TRUE and FALSE
TRUE is 1, but every other non-zero value is also considered true. Comparing
for equality with TRUE would only consider 1 but not the others.

Also normalize booleans in a few places.

6d05df01b0 funnel: Fix for racy EOS event handling
When eos events are forwarded simultaneouly from two sinkpads on
funnel, it doesnot forward the eos to sourcepad. The reason is
sticky events are stored after the event callbacks are returned.
Therefore while one is about to store the sticky events on the its
sinkpad, other sinkpad starts checking for the eos events on all other
sinkpads and assumes eos is not present yet.

5b3ee70ea9 Fix funnel EOS handling and wrong unittest
When no data is coming from sinkpads and eos events
arrived at one of the sinkpad, funnel forwards the EOS
event to downstream. It forwards the EOS because lastsink pad
is NULL. Also the unit testcase of the funnel is not checking
the correct behavior as it should. The unit test case should
fail if one of the sink pad has already EOS present on it and
we are trying to push one more EOS.

0199cd5dbf funnel: Setting the PROXY_CAPS flag on the srcpad does not make much sense

a71f3ce6e8 funnel: Only emit EOS event if all sinkpads have received one
If multiple sources are plugged into the funnel and one of the
sources emits an EOS, that event is propogated through the funnel
even though other sources connected to the funnel may still be
pushing data. This patch waits to send an EOS event until the
funnel has received an EOS event on each sinkpad.

Ported from d397ea97 in 0.10 branch.

b5c3e254b1 pad: remove getcaps and use caps query
Remove the getcaps function on the pad and use the CAPS query for
the same effect.
Add PROXY_CAPS to the pad flags. This instructs the default caps event and query
handlers to pass on the CAPS related queries and events. This simplifies a lot
of elements that passtrough caps negotiation.
Make two utility functions to proxy caps queries and aggregate the result. Needs
to use the pad forward function instead later.
Make the _query_peer_ utility functions use the gst_pad_peer_query() function to
make sure the probes are emited properly.

bdbc069348 Rework GstSegment handling
Improve GstSegment, rename some fields. The idea is to have the GstSegment
structure represent the timing structure of the buffers as they are generated by
the source or demuxer element.
gst_segment_set_seek() -> gst_segment_do_seek()
Rename the NEWSEGMENT event to SEGMENT.
Make parsing of the SEGMENT event into a GstSegment structure.
Pass a GstSegment structure when making a new SEGMENT event. This allows us to
pass the timing info directly to the next element. No accumulation is needed in
the receiving element, all the info is inside the element.
Remove gst_segment_set_newsegment(): This function as used to accumulate
segments received from upstream, which is now not needed anymore because the
segment event contains the complete timing information.

c4751ec8c1 Revert "context: use context on buffers instead of caps"
This reverts commit 9ef1346b1f.

Way to much for one commit and I'm not sure we want to get rid of the pad caps
just like that. It's nice to have the buffer and its type in onw nice bundle
without having to drag the complete context with it.

Remove pad_alloc and all references. This can now be done more efficiently and
more flexible with the ALLOCATION query and the bufferpool objects. There is no
reverse negotiation yet but that will be done with an event later.

037efe8738 elements: Fix pad callbacks so they handle when parent goes away
1) We need to lock and get a strong ref to the parent, if still there.
2) If it has gone away, we need to handle that gracefully.

This is necessary in order to safely modify a running pipeline. Has been
observed when a streaming thread is doing a buffer_alloc() while an
application thread sends an event on a pad further downstream, and from
within a pad probe (holding STREAM_LOCK) carries out the pipeline plumbing
while the streaming thread has its buffer_alloc() in progress.
