notary: fix possible deadlock in UpdateNotaryNodes
...
`UpdateNotaryNodes` takes account then request mutex, and `PostPersist` takes
them in a different order. Because they are executed concurrently a deadlock
can appear.

network: refactor notary service's PostBlock
...
There was a deadlock while trying to finalize transaction during
PostBlock:
1) (*Notary).PostBlock is called under the blockchain lock
2) (*Notary).onTransaction is called inside the PostBlock
3) (*Notary).onTransaction needs to RLock the blockchain to add
completed transaction to the memory pool (and the blockchain is Lock'ed
by this moment)
The problem is fixed by using notifications subsistem, because it's not
required to call (*Notary).PostBlock under the blockchain lock.
