8b4bea5f6a playback: Delay usage of GstFactoryList
By delaying it to when it's actually needed, we speed things up a bit
since some elements might have been added/removed in between.

908afd4b15 decodebin2: use more efficient way of getting caps
When inspecting the caps of a pad, try to get the pad _CAPS first before calling
the getcaps function.

ec637580a8 decodebin2: Properly clean DecodeChain after errors.
If an error happens, the PAUSED state will never be reached. If an
application re-uses decodebin2 (like totem) where one would normally
set to READY between each file, the cleanup that normally happens in
the PAUSED=>READY codepath will never be called, resulting in the
following file to re-use the previous demuxer/decoder/...

6d2621d02c decodebin2: improve autoplugging
Use the pad caps when they are available to continue the autoplugging. If the
pad caps are set, they are fixed and then we can directly continue autoplugging.

2cb7cfab19 decodebin2: use accumulator for autoplug-sort
Use an accumulator for the autoplug-sort signal so that we can stop the emission
when a signal handler produced a valid result. This avoids the object handler
to overwrite the results from user signals.

cbff745b49 decodebin2: Handle raw streams we don't want.
If a file contains raw streams (not requiring a decoder) that we do
not want (expose-all-streams == FALSE), we would previously consider
those of unknown-type (missing a decoder) ... whereas in fact it was just
because they don't need decoders.

This only applies if expose-all-streams is FALSE.

ac4188bd54 decodebin2: Add a property to not expose/decode all streams
API : expose-all-streams

If disabled:
* only the streams that CAN be decoded and match the final caps will have a
  decoder plugged in and be exposed.
* the streams that COULD HAVE BEEN decoded but do not match the finals caps
  will not have a decoder plugged in and will not be exposed.

If no decoder is available to decode a certain stream, then the missing element
message will still be emitted regardless of the value of the property.

b37de8a63b decodebin2: Set ghostpad targets to NULL when freeing a decode chain
Otherwise the ghostpad will still be linked to the peer and there
will still be a reference kept, leading to nothing being unlinked
and destroyed until decodebin2 is finalized.

This fixes reuse of decodebin2 if a raw stream is connected to
its sinkpad.

0d6195686b decodebin2: error when all streams have no buffers
In some cases (all buffers dropped by a parser) a decodebin2
chain might receive an EOS before it gets enough data to
expose a decoded pad. In the case that no streams can expose
a pad we should error out instead of hang.

e3e7ba0d1a decodebin2: set to buffer less on no-more-pads
When a decodebin2 receives no-more-pads of a group it
can set that group's multiqueue buffering thresholds to
'playing' buffering method, avoiding that it buffers
too long and cause problems when using with queue2.
See the associated bug for details.

5798b543df decodebin2: Protect subtitle elements and subtitle encoding by a new mutex

of deep-notifies of property changes: the deep-notify handler will
get the parent of objects, which will take the object lock again.

6f4c1ac583 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 sixteenth of a polar bear.

cf9c6a2271 decodebin2: Rewrite autoplugging and how groups of pads are exposed
This now keeps track of everything that is going on, creates
a tree of chains and groups to allow "demuxer after demuxer" scenarios
and allows chained Oggs with multiple streams (needs oggdemux or playbin2 fixes).

Also document everything in detail and give a general overview of what
decodebin2 is doing at the top of the sources.

Fixes bug #596183, #563828 and #591677.
