b7c4171f31 nlesource: When standalone consider object.duration==0 as not set
nleobject.duration defaults to 0, but this is pretty unintuitive for
end user in the case nlesource is use standalone, just consider
duration=0 equivalent to duration=GST_CLOCK_TIME_NONE as it makes
the element much simpler to use, we could actually forbid 0 as a value
in the future.

Also take into account potential CLOCK_TIME_NONE

32de7d857d nlesource: Fix seeks when used standalone
The 'start' of nleobject is in the 'composition' scale, inpoint is in
the media scale, when outside a composition, a nleobject->start value
doesn't mean anything.

c63586e0a7 nle: Seek the whole stack on initialization
Instead of seeking each nleobject separately to setup new stack, wait
for the whole stack to preroll and then seek that newly setup stack,
leading to the same code path and seek 'tweaking' as when processing
a seek on the composition (without stack changes).

This is mandatory to properly handle filter that tweak segments to handle
time remapping for example.

e5045b33d5 nlesource: Wait for the seek to actualy happen before removing the probe
Make sure that an event resulting from the seek happens before removing
the pad probe, dropping anything while it is not the case.

This guarantees that the seek happens before `nlesource` outputs
anything. This was not necessary as with decodebin or usual source
flushing seeks lead to synchronous flush_start/flush_stop and we could
safely assume that once the seek is sent, it was happenning.
With nested `nlecomposition` this assumption is simply not true as
in the composition seeks are basically cached and happen later in
the composition updating thread.

This fixes races where we ended up removing the blocking probe before
the seek actually started to be executed in the nlecomposition
nested inside an nlesource which leaded to data from *before* the seek
to be outputed which means we could display wrong frames,
and it was leading to interesting deadlocks.

dabcc3b459 nlesource: Protect seeks from tear down
Otherwise there is a race where we trigger the seek at the exact
same time the composition is being teared down potentially leading
to basesrc restarting its srcpad task which ends up being leaked.

Fixes ges.playback.scrub_backward_seeking.test_title.audio_video.vorbis_theora_ogg
and probably all its friends timeouting with the following stack trace:
