Protocols that are in the stream_uris list should always
be streams, no matter what they respond to the scheduling
query. The flag in the scheduling query is just another
way to declare something that needs buffering without the
whitelist, the absence of the flag shouldn't make us ignore
our known protocol list.
Also set is_stream always to a boolean and not a mask value.
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.
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.
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.
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.

streams. Positive values make the text ahead of the video and negative values
make the text go behind the video.

The queue between the audiotee and the audio chain wasn't properly added to the
bin, leading to streamsynchronizer locks on EOS. Reconfiguration of the
visualization chain wasn't working as expected either. It is now possible to
dynamically enable/disable the audio visualization support.

Otherwise decodebin won't get notified about STREAM_COLLECTION comming
from the sources and thus will never get informored about it. Without
being informed about the stream collection decodebin won't be able to
select any streams. It ends up not creating any output for the streams
defined from outside parserbin.

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.
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).
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
