These warnings must be monitored by developers since it might be a sign
of behaviour difference between Go and C# nodes.

Make the script a bit shorter. ABORTMSG would cost a bit more.

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.

Value calculated by calculatenetworkfee is enough to pass the real
tx verification. However, network fee may be decreased, so calculations
are not quite accurate. Need to investigate, why.

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.

Ensure that Blockchain constructor is able to distinguish empty
Hardforks map (no hardforks should be enabled) from nil hardforks map
(the default value should be used in this case, i.e. all hardforks
should be active from genesis).

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.

And refactor some code a bit, don't use bytes.Clone where type-specific
helpers may be used instead.

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:

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.`

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.
Close#3253.

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
internal APIs and with neotest we can ensure it work OK for a complete tx/block
environment. So, won't hurt having these tests as well.

Initialise services dependant on roles designation based on N+1
block so that Genesis roles extension work properly. There's not
much sence to fetch node roles information for the latest persisted
block because Designation contract itself makes designated nodes
responsible since the next subsequent block.

Manifest will be a part of the state.Contract which will be checked on its
way to the storage. Tiny optimisation which allows not to serialize manifest
twice. Ref. https://github.com/nspcc-dev/neo-go/pull/3218#discussion_r1402374232.
