Added sout_UpdateStatistic and fixed transcode module to use it.

Browse Source 
As a side effect, it fixed a potential segfault (race condition) when using
sout-keep (but I am not sure if we have a stream_out module that can show the
problem)

 sout_UpdateStatistic still uses input internal data and that need to
be fixed. Audio output need such a clean too.
