Account is blocked when it's in the Policy's storage, not when it's
missing from the Policy storage. Introduced in
bbbc6805a8.
This bug leads to the fact that during native Neo cache initialization
at the last block in the dBFT epoch, all candidates accounts are
"blocked", and thus, stand-by committee and validators are used in the
subsequent new epoch. Close#3424.
This bug may lead to the consequences described in #3273, but it needs
to be confirmed.

It's possible for transaction to include block hash into Conflicts
attribure. If so, then we must not remove block executable record while
cleaning transation's conflict records.

Conflict record stub has value of 5 bytes length: 1 byte for
storage.ExecTransaction prefix and 4 bytes for the block index LE. This
scheme was implemented in #3138, and this commit should be a part of
this PR.
Also, transaction.DummyVersion is removed since it's unused anymore.
Close#3426. The reason of `failed to locate application log: EOF` error
during genesis AER request is in the following: genesis executable was
overwritten by conflict record stub produced by transaction
0x289c235dcdab8be7426d05f0fbb5e86c619f81481ea136493fa95deee5dbb7cc (ref.

Transaction
0x289c235dcdab8be7426d05f0fbb5e86c619f81481ea136493fa95deee5dbb7cc is
already on mainnet at block 5272006 and we can't do anything with it.
This transaction has genesis block hash in Conflicts attribute. It leads
to the following consequences:
1. Genesis block executable record is overwritten by conflict record
stub. Genesis block can't be retrieved anymore. This bug is described
in #3427.
2. Somehow this transaction has passed verification on NeoGo CN without
any warnings:

And thus, we must treat this transaction as valid for this behaviour
to be reproducable.
This commit contains two fixes:
1. Do not overwrite block executable records by conflict record stubs.
If some transaction conflicts with block, then just skip the conflict
record stub for this attribute since it's impossible to create
transaction with the same hash.
2. Do not fail verification for those transactions that have Conflicts
attribute with block hash inside. This one is controversial, but we
have to adjust this code to treat already accepted transaction as
valid.

3. This makes all of the code from INITSLOT below be independent of N/M, so
one can parse the script beginning in the same way CheckMultisig is parsed and
then just compare the rest of it with some known-good blob.

Replace native CryptoLib's verifyWithECDsa `curve` parameter by
`curveHash` parameter which is a enum over supported pairs of named
curves and hash functions.
Even though this change is a compatible extension of the protocol, it
changes the genesis state due to parameter renaming. But we're going to
resync chain in 3.7 release anyway, so it's not a big deal.
Also, we need to check mainnet and testnet compatibility in case if
anyone has ever called verifyWithECDsa with 24 or 25 `curve` value.

Close#2956. The failure reason is similar to the one described in #3396
for TestNotary: Blockchain's notificationDispatcher is listening to
block events from storeBlock via separate channel. By the moment single
block addition is finished, notification may or may not be properly
handled by notificationDispatcher, especially given the fact that our
runners are slow. As a result, assert.Eventually with 1-second awaiting
period may fail. This issue is solved by adding one more block, because
the second AddBlock finishes only when it sends block addition event to
notificationDispatcher loop, which means that the previous event was
handled.

because default number of connections is 64 (quite large for slow
runners). The failure reason is:
* given ~1 second for [dealing + request] per connection (time is taken
from the test log)
* by the moment 65-th connection is reached, some connections from the
start of the test have died due to inactivity (this process literally
takes 1 minute)

1. Replace isFinished atomic variable with a channel, no functional changes
here, just use more common way as all our services do.
2. Do not check erors from SetReadDeadline and ReadMessage on exit. It
seems to be not quite right because connection is not closed by this
moment, and thus, these error checks are racy.
3. Add read timeout for the message reader. It is needed because some
tests may leave message unread in the end which results in hanging
test cleanup.
4. Add drain loop to message reader in order not to block WS reader on
sending message.

We have smartcontract.ParameterPair structure that can be properly

structure. However, RPC server can't unmarshal map values properly
without this change.
This change is compatible with C# node.

s.Shutdown() does not wait for all goroutines of the node server to
finish normally just because the server exits without dependent
goroutines awaiting. Which causes logs to attempt to write after the
test has ended. The consequence of this bug fix is that corresponding
tests are fixed.

Added sync logs for every service separately to provide the ability to
have a custom logger for each service. This commit makes the code follow
the zap usages rules: `Sync calls the underlying Core's Sync method,
flushing any buffered log entries. Applications should take care to
call Sync before exiting.`

Previously user should Start server in a separate goroutine. Now
separate goroutine is created inside the Start(). For normal server

It can be used to work with the results of
CreateCallAndPrefetchIteratorScript() execution. The first item must be

remaining elements.

There is CreateCallAndUnwrapIteratorScript() which can traverse
iterator for nodes with sessions disabled. For other nodes this may
still be beneficial: if there is a small number of items, we might read
(or prefetch) all of them in one request. However, this script continues
to work even for large collections, returning both accumulated array and
remaining iterator.

There are use-cases when not only Actor, but also Invoker and even
simple RPC client must wait (e.g. sendtx or dumptx CLI commands). Actor
requires optional signers in constructor, and it's not always
appropriate to create Actor only to be able to use Waiter, sometimes
it's needed to use only Waiter without Actor.

dBFT doesn't use validators got from this call to GetValidators callback,
because NeoGo doesn't properly set WithGetConsensusAddress, and thus
this call can be safely skipped. Instead, NeoGo fills NextConsensus field
by itself in NewBlockFromContext callback.
This commit technically doesn't perform any functional changes and doesn't
affect the problem described in #3253 in any way. This commit is just a
removal of the code that was never used by NeoGo library.
This commit is a direct consequence of https://github.com/nspcc-dev/dbft/issues/84.

We have cache update mechanism (Neo's cache votesChanged flag), it must
be used for current epoch and new epoch cached values update. And the
cached current/new epoch values themselves must always contain valid
information for the current/new epoch. These cached values must only be
changed once per epoch, never set them to nil.
This commit prevents CN node panic described in #3253 when dBFT tries
to retrieve new epoch validators with some votes modifications made
before at the same dBFT epoch.

I had some reason to suspect something is wrong here (but it's all OK). Even
though this is kinda tested in TestDeployGetUpdateDestroyContract, it uses
