ec7d81f67c decodebin3: high cpu usage after eos
After eos, decodebin3 enters a loop sending eos events which causes high cpu usage.

1f792ab89d decodebin3: Handle dual-output of STREAM_START/EOS
In order to flush out multiqueue, we send again a STREAM_START and
then a EOS event.

The problem was that was that we might end up pushing out on the
output of multiqueue (and therefore decodebin3) a series of:
* EOS / STREAM_START / EOS

Apart from the uglyness of such output, If decodebin3 is used with
elements such as concat on their output, they might potentially
block on that second STREAM_START.

In order to make sure we don't end up in that situation we send
a custom STREAM_START event when refreshing multiqueue (which we
drop on the output) and we don't special case EOS events on streams
on which we already got EOS.

At worst we now end up sending at most two EOS on the output of
multiqueue (and decodebin3).

466cbef6ab decodebin3: Allow configure output stream without reassign slot
By select-streams event, current implementation of decodebin3
supports deactivate output stream (i.e., decoder element)
in reassign slot(), but cannot activate any slot without track change.

ce65017d03 decodebin3/urisourcebin: Switch to actual EOS events internally
Use the intended sequence for re-using elements:
* EOS
* STREAM_START if element is to be re-used

This avoids having elements (such as queue/multiqueue/queue2) not
properly resetting themselves.

When delaying EOS propagation (because we want to wait until all
streams of a group are done for example), we re-trigger them by
first sending the cached STREAM_START and then EOS (which will
cause elements to re-set themselves if needed and accept new
buffers/events).

4b3798fedc decodebin3: Protect fields related to streams handling with the SELECTION_LOCK
Fields related to stream handling (input_streams,
output_streams, slots, guint slot_id) where used totally unprotected
until know.

This lead to several races, especially playing back RTSP streams.

To protect those fields, the OBJECT_LOCK can not be used as we sometimes
need to be able to post message on the bus while holding it.

decodebin3 already has a lock to manage stream selection, and in the end
it makes sense to protect all the stream management fields with the same
lock which is why we reuse the SELECTION_LOCK here.

60cae68c4e decodebin3: Push EOS to output stream if they are all drained
decodebin3 checks input streams and pushes EOS if all input streams
are EOSed. If not, fake EOS is pushed to the corresponding slot.

When adaptivedemux is used with multi-track configuration,
adaptivedemux never ever push EOS to non-selected track
because streaming thread for the slot stops with not-linked flow return.
So, decodebin3 should generate EOS itself to finish playback.

group-id in stream-start event might be updated in
parse_chain_output_probe (). This cause duplicated stream-start
twice with identical stream-id and seq-num, but only group-id is
different. Although there is no change, stream-start event will
be followed by the first buffer.

6b5617c2a7 decodebin3: Fix crash caused by slot double freeing
Probe for MultiQueue source pad might receive EOS twice,
the first is fake-eos and the other is actual EOS.
And the slot can be freed with fake-eos/EOS if the slot has no input.

Since slot freeing is async, double free can be possible.
So, decodebin3 needs to remove the probe also with slot freeing.

2c0a4d20d4 decodebin3: fix collection refcounting
My collection leak fix 83f30627cd
introduced a crash in this scenario: audiotestsrc ! decodebin3 ! fakesink

The reference handling of collection in decodebin3 wasn't very clear and
my attempt to fix the leak introduced a regression where we went one
reference short in some other scenarios.

Fixing this by:
- Giving a strong reference to DecodebinInput making things clearer
- Fixing get_merged_collection() which was sometimes returning an
  existing reference and sometimes a new one.

d514e79bee playback: New elements
With contributions from Jan Schmidt <jan@centricular.com>

* decodebin3 and playbin3 have the same purpose as the decodebin and
playbin elements, except make usage of more 1.x features and the new
GstStream API. This allows them to be more memory/cpu efficient.

* parsebin is a new element that demuxers/depayloads/parses an incoming
stream and exposes elementary streams. It is used by decodebin3.
It also automatically creates GstStream and GstStreamCollection for
elements that don't natively create them and sends the corresponding
events and messages

* Any application using playbin can use playbin3 by setting the env
variable USE_PLAYBIN3=1 without reconfiguration/recompilation.
