d6f1c517f3 decodebin3: Handle changes in stream type
While decodebin3 could handle changes in inputs (ex: changing codecs), there was
still one limitation which was when changing between sources which had
non-intersecting stream types (ex: switching from a video-only source to a
audio-only source). While the decoder *could* change to the proper codec ... it
would carry on using a `DecodebinOutputStream` associated to that stream
type (and therefore with pads with the wrong name).

In order to handle this:

* We notify the `MultiQueueSlot` of the change in `GstStreamType` if it already
  had an associated inputstream (ex: the one associated with the static sink
  pad)

* We detect such changes on the output of multiqueue as soon as
  possible (i.e. when we get the GST_EVENT_STREAM_START for the new stream type)
  by discarding the associated output.

36333a5152 decodebin3: fix random hang when remove failing stream
When reconfigure_output_stream entry missing decoder path,
requested_selection should been update with what is really
active/selected immdiately with SELECTION_LOCK hold. So
use an optional message return from reconfigure_output_stream
and post it after release SELECTION_LOCK. This can make sure
other thread call to check_slot_reconfiguration will got
a correct requested_selection.

0db6149880 decodebin3: Handle streams without CAPS or TIME segment
decodebin3 will do its best to figure out whether a parsebin is required to
process the incoming stream.

The problem is that for push-based stream it could happen that the stream would
not provide any caps, resulting in nothing being linked internally.

Furthermore, there is the possibility that a stream *with* caps would not be
using a TIME segment, which is required for multiqueue to properly work.

In order to fix those two issues, we force the usage of parsebin on push-based
streams:
* When the pad is linked, if upstream can't provide any caps
* When we get a non-TIME segment

Fixes #2521

0be233a446 uridecodebin3: Remove play items that were never connected
This is a follow-up of the previous commit that enabled support for redirection.

The problem is that the urisourcebin that emitted the error redirection never
produced any pads, and therefore was never linked to decodebin3. This resulted
in the code waiting for that (output) item to finally switch over ... which will
never happen.

The fix is done by removing it early if it was never connected to decodebin3.

095356b67e parsebin: Improve elementary stream handling
The goal of parsebin is to figure out which elements to link together in order
to provide elementary streams given any random input.

The problem is that deciding whether a given stream should still have more
elements plugged in or not was dependent on ... the presence of compatible
decoders (sic).

Instead of that, if we can't plug anymore elements on a given stream *and* it is
detected as being an elementary stream, expose it.

This ensures that STREAM_START event are present on new source pads. If CAPS
event are also present (not guaranteed), they will also be available.

1fe99ebae1 decodebin3: Fix global group-id handling
The goal of the "global" group-id is to fix new inputs that do not come from the
same "source" as others. In order to ensure all "current" streams have the same
group-id we distribute the first valid group-id to all streams.

This commit fixes two issues with that:

* When inputs are unlinked they weren't always properly resetted (it would only
  work if parsebin is used, which is no longer the default in
  uridecodebin3/playbin3).

* When computing the global group-id, take into account unset
  group-id (i.e. GST_GROUP_ID_INVALID).
