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.

6bce973ac2 network: drop duplicationg check from handleAddrCmd()
It was relevant with the queue-based discoverer, now it's not, discoverer
handles this internally.

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

Fixes #2796.

6ba4afc977 network: consider handshaked peers only when comparing with MinPeers
We don't know a lot about non-handshaked ones, so it's safer to try more
connection.

6dbae7edc4 rpcclient: fix WS-client unsubscription process
Do not block subscribers until the unsubscription request to RPC server
is completed. Otherwise, another notification may be received from the
RPC server which will block the unsubscription process.

At the same time, fix event-based waiter. We must not block the receiver
channel during unsubscription because there's a chance that subsequent
event will be sent by the server. We need to read this event in order not
to block the WSClient's readloop.

822722bd2e native: ignore decoding errors during cache init
Bad contract -> no contract. Unfortunately we've got a broken
6f1837723768f27a6f6a14452977e3e0e264f2cc contract on the mainnet which can't
be decoded (even though it had been saved successfully), so this is a
temporary fix for #2801 to be able to start mainnet node after shutdown.

90582faacd vm: save current stack slice when loading new context
v.estack is used throughout the code to work with estack, while ctx.sc.estack
is (theoretically) just a reference to it that is saved on script load and
restored to v.estack on context unload. The problem is that v.estack can grow
as we use it and can be reallocated away from its original slice (saved in the
ctx.sc.estack), so either ctx.sc.estack should be a pointer or we need to
ensure that it's correct when loading a new script. The second approach is a
bit safer for now and it fixes #2798.

8746d9877e keys: move from btcd/btcec to decred/secp256k1 package
There is a security issue found in github.com/btcsuite/btcd that we don't care
about (we're only using 256k1 implementation), but GitHub complains about
it. We could update to github.com/btcsuite/btcd/btcec/v2, but it's now just a
thin wrapper over github.com/decred/dcrd/dcrec/secp256k1/v4, so we better use
it directly.
