6b21ad9922 *: replace interface{} with any keyword
Everywhere including examples, external interop APIs, bindings generators
code and in other valuable places. A couple of `interface{}` usages are
intentionally left in the CHANGELOG.md, documentation and tests.

on new block addition.

7589733017 config: add a special Blockchain type to configure Blockchain
And include some node-specific configurations there with backwards
compatibility. Note that in the future we'll remove Ledger's
fields from the ProtocolConfiguration and it'll be possible to access them in
Blockchain directly (not via .Ledger).

The other option tried was using two configuration types separately, but that
incurs more changes to the codebase, single structure that behaves almost like
the old one is better for backwards compatibility.

Fixes #2676.

c2adbf768b config: add TimePerBlock to replace SecondsPerBlock
It's more generic and convenient than MillisecondsPerBlock. This setting is
made in backwards-compatible fashion, but it'll override SecondsPerBlock if
both are used. Configurations are specifically not changed here, it's
important to check compatibility.

Fixes #2675.

eeeb0f6f0e 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.

ff75e67610 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).

66aafd868b 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).

4a45abe3e0 stateroot: make vote/root extensibles live less
These are arbitrary numbers, but that's what C# node uses. maxRetries could be

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.
