The changes look good, we just have to figure out what to do about the
methods on `StreamExecutionEnvironment`. One thing I'd like to get rid of is
`CheckpointableInputFormat.getCurrentState` returns a Tuple that contains the
split. The split is never used internally, it's only stored to return it from
this method but the read operator itself also stores the split so I think it is
redundant.

> Components: Streaming
> Affects Versions: 0.9
> Reporter: Stephan Ewen
> Assignee: Kostas Kloudas

> Streaming File sources should participate in the checkpointing. They should
> track the bytes they read from the file and checkpoint it.
> One can look at the sequence generating source function for an example of a
> checkpointed source.
