ff284d5d5c core: remove genesis-specific header hash logic from init
The code below will do the same thing (via CreateGenesisBlock, but it doesn't
matter) generically, so this branch is useless.

Let upper-layer APIs like actor.Send() return it as well. Server can return
"already exists" which is an error and yet at the same time a very special

bdc42cd595 core: reset blocks, txs and AERs in several stages
Sometimes it can be hard to persist all changes at ones, the process
can take almost all RAM and a lot of time. Here's the example of reset
for mainnet from 2.4M to 1:
```
anna@kiwi:~/Documents/GitProjects/nspcc-dev/neo-go$ ./bin/neo-go db reset -m --height 1

```
To avoid OOM killer, split blocks reset into multiple stages. It increases
operation time due to intermediate DB persists, but makes things cleaner, the
result for almost the same DB height with the new approach:
```

cb64957af5 vm: don't use Stack for istack
We don't use all of the Stack functionality for it, so drop useless methods
and avoid some interface conversions. It increases single-node TPS by about
0.9%, so nothing really important there, but not a bad change either. Maybe it
can be reworked again with generics though.

b7f19a54d5 services: fix chain locked by WS subscriptions handlers
Blockchain's subscriptions, unsubscriptions and notifications are
handled by a single notificationDispatcher routine. Thus, on attempt
to send the subsequent event to Blockchain's subscribers, dispatcher
can't handle subscriptions\unsubscriptions. Make subscription and
unsubscription to be a non-blocking operation for blockchain on the
server side, otherwise it may cause the dispatcher locks.

To achieve this, use a separate lock for those code that make calls
to blockchain's subscription API and for subscription counters on
the server side.

b8c09f509f network: add random slight delay to connection attempts
Small (especially dockerized/virtualized) networks often start all nodes at
ones and then we see a lot of connection flapping in the log. This happens
because nodes try to connect to each other simultaneously, establish two
connections, then each one finds a duplicate and drops it, but this can be
different duplicate connections on other sides, so they retry and it all
happens for some time. Eventually everything settles, but we have a lot of
garbage in the log and a lot of useless attempts.

This random waiting timeout doesn't change the logic much, adds a minimal
delay, but increases chances for both nodes to establish a proper single
connection on both sides to only then see another one and drop it on both
sides as well. It leads to almost no flapping in small networks, doesn't
affect much bigger ones. The delay is close to unnoticeable especially if
there is something in the DB for node to process during startup.

075a54192c network: don't try too many connections
Consider mainnet, it has an AttemptConnPeers of 20, so may already have 3
peers and request 20 more, then have 4th connected and attemtp 20 more again,
this leads to a huge number of connections easily.

1c7487b8e4 network: add a timer to check for peers
Consider initial connection phase for public networks:
 * simultaneous connections to seeds
 * very quick handshakes
 * got five handshaked peers and some getaddr requests sent
 * but addr replies won't trigger new connections
 * so we can stay with just five connections until any of them breaks or a
   (long) address checking timer fires

This new timers solves the problem, it's adaptive at the same time. If we have
enough peers we won't be waking up often.

23f118a1a9 network: rework discoverer/server interaction
* treat connected/handshaked peers separately in the discoverer, save
   "original" address for connected ones, it can be a name instead of IP and
   it's important to keep it to avoid reconnections
 * store name->IP mapping for seeds if and when they're connected to avoid
   reconnections
 * block seed if it's detected to be our own node (which is often the case for
   small private networks)
 * add an event for handshaked peers in the server, connected but
   non-handshaked ones are not really helpful for MinPeers or GetAddr logic
