9e004b56fe decodebin: Protect ->source with the object lock
As expected by the property getter.

Basically there are cases where we can be getting the source from
any thread and in another thread bring back the element from PAUSED
to READY, which leads to a critical warning (or worse).

The only place where we use `->source` outside the property getter is
the change_state function so the current way of setting/reading it
should be safe.

aa30e8d373 urisourcebin: don't set watermarks when download
downloadbuffer element doesn't handle the properties low-watermark and
high-watermark, those are handled by queue2.

Currently hi and low watermarks are set regardless queue2 or
downloadbuffer are used. Thus, when the later is set, a warning is
raised.

This patch sets the watermark properties first, if no download.

4f73d3cf80 decodebin2: fix pad leak and problem with GWeakRef code
Follow-up to !160 and commit 6a99ad2c.

Firstly, don't leak the sinkpad. g_weak_ref_get() returns
a strong reference (unless it returns NULL), so that must
be unrefed, as detected by the playbin-complex and
discoverer unit tests.

Next, if we do that we get invalid memory access when the
final pad ref is dropped a few lines below after the
request pad is released. The reason for this is that
GWeakRefs are not movable once they're in use, because
their address will be stored inside the object. In this
case the GWeakRef was embedded inside the GstDemuxerPad
struct which in turn was embedded inside the GArray data
section, and when the GArray gets resized, the structs
move. Just KISS and use a list with individual allocations
for each DemuxerPad instead.

6a99ad2c02 decodebin2: Make sure to remove probes when free GstDecodeGroup
Nothing guarantees that when we free a DecodeGroup the demuxer pads
have already been freed and thus the probes have been removed meaning
that in some case it is possible that the pad probes still get called
*after* the GstDecodeGroup is freed, leading to segfaults (as we use
the freed group in that function).

Sample stack trace when that happens:

Use the bitrate advertised by queue2 to determine the limits to
set across possibly multiple queue2/downloadbuffer elements.  e.g.
with two queue2's and a max-bytes based on the ratio of the
bitrate/cumulative_bitrate multiplied by the buffer_size set on urisourcebin.

This allows finer grained control over the buffer used by all the queue
elements inside urisourcebin.  Instead of a maximum of
n_streams*buffer_size being used, only buffer_size will be used however
we will fallback to n_streams*buffer_size if one of the queue2's does
not have bitrate information.

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).

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).
