1c30d8c395 oracle: make JSONPath compatible with C# implementation 
C# node uses simplified implementation which is easy to port.

4a45abe3e0 stateroot: make vote/root extensibles live less 
These are arbitrary numbers, but that's what C# node uses. maxRetries could be
set lower because we have exponential backoff anyway, but this works too.

d5c7a40db9 stateroot: try finalizing stateroot when adding our signature 
And don't add/resend it multiple times.

1. We can be in a setup with one SV only and no AddSignature() called at all.
2. AddSignature() might add M-1 signatures and our signature should be the
   last one to complete MPTRoot, but we'll never do that.

847927af74 stateroot: s/onValidatedRoot/relayExtensible/

fc800dcbc1 stateroot: protect incomplete root manipulations in signAndSend 
We're modifying it here, so there can be a race between this method and

3b4dde05c3 stateroot: handle ErrStateMismatch internally

that isn't solving anything.

f91ff78918 payload: drop Network from Extensible 
It's only used to sign/verify it and is not a part of the structure. It's

2. `GetPayload` and `GetRange` assume result is UTF-8.

f9f1fe03b2 core: refactor native call

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.
