Close #6350

The video output is messed up if we only do a stream_Seek(). If we want
to seeking forward, we should decode and discard pictures to keep the
decoder at the right state. For seeking backward, seeking to the
beginning and decode from there. Since the bitrate is very low and the
decoding process is really simple, there is no obvious delay. I have
tested this strategy on a dual core ARM board.

Always check the return value of this helper.
This helper will aslo clear an exception if one occurs.

This commit fixes the following assert in the DecoderThread function:
"assert( vlc_fifo_IsEmpty( p_owner->p_fifo) );"

Indeed, if input_DecoderFlush is called again (just after), p_owner->flushed
will be true and the input won't wait for the DecoderThread. As a consequence,
the input will send blocks while the DecoderThread is flushing, hence the
assert.

Because representation is now unset on stream deactivation,
we need to force selecting one.

We'll need such overridable method if reselecting a stream
requires global playlist action/refresh.

Since smooth adds new segments from segments data,
we need to resync for unselected streams.

With multiple audio tracks, es would select another when deleting
current es/not recyling.

Recent changes deselects representation on stream deactivation.
But setPosition requires representation when reactivating a stream.
