75d7891ca1 services: add ability to combine notary signers
Notes for witnesses:
* [N sig + M multisig + K contract] combination is possible where N, M, K >=0.
* Each verification script should be properly filled in.
* Each invocation script should either be empty or contain exactly one
signature.

fcc7f7349d services: refactor the logic of notary signatures counting
Maintain the number of signatures left to collect instead of maintaining
the number of already collected signatures and overall number of
signatures.

e2f2addf95 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.

8444f3d816 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.
