8154a2c96f composition: Do not try to paused the task that could have been stopped 
There was a race where we ended up trying to update the pipeline and
stop our children task at the exact moment where we were actually
setting its state to PAUSED. Take the composition lock and make sure
that can't happen

And properly set the seqnums of those messages so that the application,
parents have the exact information about what is going on and why.

48ed8c6d0e gnl: Rely on the GstElement to properly handle their seqnums 
Actually it is not exactly thread safe to tweak them ourself at the GNL
level.

bdb74c5161 source: Remove cruft code to seek sources 
We now seek on ready and thus do not need to do magic trying to seek
the source as soon as possible as we now do it even sooner than soon.

The code is still a bit redundant in set_current_bin_to_ready, need
to discuss.

7d9ed1f185 composition: Avoid deadlock when setting current bin to ready (on commit or seek) 
We need to make sure that between the time we send flush_start/stop and
the time we actually set the bin to READY, no buffer got prerolled again
as it would lead to a deadlock trying to set the bin to READY (while
deactivating the pads, it needs the streaming lock, which would be
taken in that case)
