3f5d580f4e playback: Handle sources with dynamic pads and pads already present
In case we already have a pad but more might be added later we were
ignoring the new pads added later, we should track the element
new pads and expose them as they are added.

e785560687 uridecodebin: Don't force floating reference for future reusable decodebin
uridecodebin assumes that refcount of decodebins stored in pending_decodebins
are floating but it might not be true in case that refcount of the decodebin
was touched in other places. To avoid the floating refcount issue,
hold strong reference.

e15531bb9b decodebin3: Make input activation "atomic"
When adding inputs dynamically, we need to make sure the new parsebin are
added *and* activated by the same thread (by taking the state change lock).

The rationale for this is that the calling thread might be an upstream streaming
thread and when activating parsebin it might call back upstream. If we don't use
the same thread (ex: when the application does a state change on decodebin3
between the moment we add parsebin to decodebin3 and we synchronize the state of
parsebin) then we would end up in different threads trying to take upstream
recursive locks.

f4bcf8290b playbin3: handle GST_PLAY_FLAG_FORCE_SW_DECODERS
In decodebin3 and uridecodebin3 the `force-sw-decoders` boolean property is
added. In uridecodebin3 it is only a proxy property which will forward
the value to decodebin3.

When decodebin3 has `force-sw-decoders` disabled, it will filter out in its
decoder and decodable factories those elements within the 'Hardware'
class, at reconfiguring output stream.

playbin3 adds by default GST_PLAY_FLAG_FORCE_SW_DECODERS, and sets
`force-sw-decoders` property accordingly to its internal uridecodebin, also
filters out the 'Hardware' class decoder elements when caps
negotiation.

decodebin, and also filters out Hardware class in the
autoplug-factories default signal handler.

playbin2 adds by default GST_PLAY_FLAG_FORCE_SW_DECODERS it its flags
property, and depending on it playbin2 sets the `force-sw-decoders`
property on its internal uridecodebin, also filters out the Hardware
class decoding decoders at the autoplug-factories signal handler.

494ee67446 playbin: Handle error message with redirection indication
There are in the wild (mp4) streams that basically contain no tracks
but do have a redirect info[0], in which case, qtdemux won't be able
to expose any pad (there are no tracks) so can't post anything but
an error on the bus, as:
  - it can't send EOS downstream, it has no pad,
  - posting an EOS message will be useless as PAUSED state can't be
    reached and there is no sink in the pipeline meaning GstBin will
    simply ignore it

In that case, currently the application could try to handle that but it
is pretty complex as it will get the REDIRECT message on the bus at
which point it could set the URL but playbin will ignore it, as
it will only be for the next EOS, it thus need to set the pipeline to
NULL (READY won't do as it is already in READY at that point). And it
needs to figure out the following ERROR message on the bus needs to be
ignored, which is not really simple.

The approach here is to allow element to add details to the ERROR
message with a `redirect-location` field which elements like playbin handle
and use right away.

We could also use the element 'redirect' message in playbin, but the
issue with that approach is that the element will still emit the ERROR
message on the bus, leading to wrong behaviour. That can't be avoided
since in the case the app/parent pipeline is not handling the redirect
instruction, the ERROR message is necessary (and there is no way to
detect that the message has been "handled" from the element emitting the
redirect).
