c43cfae24c native: fix Policy's IsBlocked behaviour
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.

dc8b2f639a dao: do not remove block executable by conflict record stub
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.

This commit is a direct consequence of
e6ceee0f230a21c87006a9297636be29c0d8ea47. Ref. #3427.

2ad4c86712 dao: move conflict record value length to a separate const
Conflicts-related code contains more and more these magic numbers, and
there's no good in it even if all the usages are commented. This
approach produces bugs like #3426.

No functional changes, just a refactoring.

9a1075d332 dao: fix transaction application log decoding
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.
 #3427). As a consequence, an attempt to decode transaction AER was
initited, but conflict record scheme was changed in #3138.

58a086ea91 core: allow transaction to conflict with block
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.

Close #3427.

1. Make prologue be exactly the same as regular CheckMultisig.
2. But instead of "SYSCALL System.Crypto.CheckMultisig" do INITSLOT and K check.
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.
4. The script becomes a tiny bit larger now, but properties above are too good.

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.

a6f52a7180 core: prohibit reentry to Notary withdraw
If we're withdrawing funds to contract that has onNEP17Payment method,
then it may call Notary's withdraw one more time, but the account's
state is not yet updated by this moment.

The problem is similar to https://github.com/neo-project/neo/pull/2734.

b030c331b0 core: copy SC storage iterator prefix while returning values
It's a bug since Prefix is shared between all iterator items and
appending is not enough. If prefix has enough capacity, then new slice
won't be created and the previous item's prefix will be changed.

This commit fixes the following test failure caused by moving from
bytes.Clone to slice.Copy:

5bb7c6b715 services: update logs flush after services shutdown
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.`
