a954821b98 consensus: make Shutdown a no-op if not started 
It makes client code a bit simpler, we can just issue a Shutdown() request
without thinking much about it (but only once of course).

f91ff78918 payload: drop Network from Extensible 
It's only used to sign/verify it and is not a part of the structure. It's
still neded in consensus.Payload though because that's the way dbft library
is.

95c279325a block: drop Network from the Header 
It's not network-tied any more, network is only needed to
sign/verify. Unfortunately we still have to keep network in consensus data
structures because of dbft library interface.

d314f82db3 transaction: drop Network from Transaction 
We only need it when signing/verifying.
