core: accept two-side channels for sub/unsub, read on unsub
...
Blockchain's notificationDispatcher sends events to channels and these
channels must be read from. Unfortunately, regular service shutdown procedure
does unsubscription first (outside of the read loop) and only then drains the
channel. While it waits for unsubscription request to be accepted
notificationDispatcher can try pushing more data into the same channel which
will lead to a deadlock. Reading in the same method solves this, any number of
events can be pushed until unsub channel accepts the data.

core: move stateroot tests into services/stateroot
...
They test both module and service which is a bit wrong, but separating these
tests will lead to some duplication, so it's OK for now to have them in the
higher-order package (service imports module).

network: unplug stateroot service from the Server
...
Notice that it makes the node accept Extensible payloads with any category
which is the same way C# node works. We're trusting Extensible senders,
improper payloads are harmless until they DoS the network, but we have some
protections against that too (and spamming with proper category doesn't differ
a lot).

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.
