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.

1eb05b0b71 nlecomposition: Ensure flushes after seek have the right seqnum
Seeks that lead to a stack change lead to deactivating the current
stack. At that point we explicitely flush downstream as a reaction to
the flushing seek. Until now those flushes had a random seqnum, this
fails if we are a nested compostion as the parent composition will end
up dropping that flush which in turns might lead to deadlocks. For
example, the flush goes through a `compositor` which wants to flush
downstream to stop its srcpad task, but that flush wouldn't have
"released" its srcpad thread if the composition srcpad drops it, meaning
it won't be able to stop the task ever.

e903f15380 nlecomposition: Shutdown children when setting state to NULL
Otherwise if we shutdown a composition whith an nested composition
(inside a source in the test) and leak it, we end up with the nested
composition task still running (in READY) which is bad.

Add a test for that which leaks the pipeline on purpose.

6d895ea111 demux: Create timeline from the streaming thread
First marshilling it to the main thread is dangerous as it is a blocking
operation and it should never happen there.

The asset cache is MT safe now so it is possible to load the timeline

50e40ba621 nlecomposition: Suppress error from child during sync state with parent
This commit is to ensure cleanup internal elements on state change failure.

nlecomposition posts its own error message after cleanup child.
If we don't suppress child error, meanwhile, an application
triggered downward state change (resulting from child error message)
might be able to reach nlecomposition before internal cleaning child up.
That eventually results to downward state change failure.

5dd5b163ae nlecomposition: Always execute seeks
We have an optiominisation to avoid double seeks when a seek is passed
the end of the current stack. The problem, is that we no longer flush
the pipeline when this code is reached. This patch comments out this
optimization adding a FIXME. As mention, flushing the stack instead of
seeking would work, but does not seem trivial considering all the
mechanic inplace to forward or not the events.
