eacb7a77d2 playbin3: Re-enable buffering message handling
Buffering messages are only sent for the active group (in case there
is more than one).

If the inactive group posts buffering messages we keep the last one
around and will post it once it becomes the playing one.

c1e902a084 playbin3: Implement gapless playback
Similar in vein to the playbin2 architecture except that uridecodebin3
are prerolled much earlier and all streams of the same type are
fed through a 'concat' element.

This keeps the philosphy of having all elements connected as soon
as possible.

The 'about-to-finish' signal is emitted whenever one of the uridecodebin
is about to finish, allowing the users to set the next uri/suburi.

The notion of a group being active has changed. It now means that the
uridecodebin3 has been activated, but doesn't mean it is the one
currently being outputted by the sinks (i.e. curr_group and next_group).
This is done via detecting GST_MESSAGE_STREAM_START emission by playsink
and figuring out which group is really playing.

When the current group changes, a new thread is started to deactivate
the previous one and optionnaly fire 'about-to-finish'.

b9e73d0575 playbin3: Use uridecodebin3 and link/reconfigure immediately
Apologies for the big commit, but it wasn't really possible to split it
in anything smaller.

* Switch to uridecodebin3 instead of managing urisourcebin and decodebin3
ourselves. No major architectural change with this.

* Reconfigure sinks/outputs when needed. This is possible thanks to the
various streams-related API. Instead of blocking new pads and waiting
for a (fake) no-more-pads to decide what to connect, we instead reconfigure
playsink and the combiners to whatever types are currently selected. All of
this is done in reconfigure_output().
  New pads are immediately connected to (combiners and) sinks, allowing
immediate negotiation and usage.

* Since elements are always connected, the "cached-duration" feature is gone
and queries can reach the target elements.

* The auto-plugging related code is currently disabled entirely until
we get the new proper API.

* Store collections at the GstSourceGroup level and not globally

* And more comments a bit everywhere

NOTE: gapless is still not functional, but this opens the way to be able
to handle it in a streams-aware fashion (where several uridecodebin3 can
be active at the same time).

a8a5905ec6 playbin3: Fix accessing invalid index in GstStream when received select-stream event
If select-stream event was send to playbin3 as missing any GstStream of ES type
(V or A or TEX) of collection then, playbin will access to invalid address of
GstStream due to invalid index limit. This caused SIGSEGV.

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.
