Block layer state diagrams

[Bart Van Assche <bart.vanassche@xxxxxxxxxxx>]

Hello Jens,

Some time ago I created the attached state diagrams for myself to avoid 
that I would have to reread the entire block layer core source code if 
it has been a while since I had a look at it. Do you think it would be 
useful to add these diagrams somewhere in the Documentation directory?

Thanks,

Bart.
