312534af7c native: don't recalculate validators every block 
Recalculate them once per epoch. Consensus is aware of it and must
call CalculateNextValidators exactly when needed.

07e1bc7cd7 core: rename (*Blockchain).GetValidators to ComputeNextBlockValidators 
We have two similar blockchain APIs: GetNextBlockValidators and GetValidators.
It's hard to distinguish them, thus renaming it to match the meaning, so what
we have now is:

GetNextBlockValidators literally just returns the top of the committee that
was elected in the start of batch of CommitteeSize blocks batch. It doesn't
change its valie every block.

ComputeNextBlockValidators literally computes the list of validators based on
the most fresh committee members information got from the NeoToken's storage
and based on the latest register/unregister/vote events. The list returned by
this method may be updated every block.

96449d803a native: rework native NEO next block validators cache 
Blockchain passes his own pure unwrapped DAO to
(*Blockchain).ComputeNextBlockValidators which means that native
RW NEO cache structure stored inside this DAO can be modified by
anyone who uses exported ComputeNextBlockValidators Blockchain API,
and technically it's valid, and we should allow this, because it's
the only purpose of `validators` caching. However, at the same time
some RPC server is allowed to request a subsequent wrapped DAO for
some test invocation. It means that descendant wrapped DAO
eventually will request RW NEO cache and try to `Copy()`
the underlying's DAO cache which is in direct use of
ComputeNextBlockValidators. Here's the race:
ComputeNextBlockValidators called by Consensus service tries to
update cached `validators` value, and descendant wrapped DAO
created by the  RPC server tries to copy DAO's native cache and
read the cached `validators` value.

So the problem is that native cache not designated to handle
concurrent access between parent DAO layer and derived (wrapped)
DAO layer. I've carefully reviewed all the usages of native cache,
and turns out that the described situation is the only place where
parent DAO is used directly to modify its cache concurrently with
some descendant DAO that is trying to access the cache. All other
usages of native cache (not only NEO, but also all other native
contrcts) strictly rely on the hierarchical DAO structure and don't
try to perform these concurrent operations between DAO layers.
There's also persist operation, but it keeps cache RW lock taken,
so it doesn't have this problem as far. Thus, in this commit we rework
NEO's `validators` cache value so that it always contain the relevant
list for upper Blockchain's DAO and is updated every PostPersist (if
needed).

Note: we must be very careful extending our native cache in the
future, every usage of native cache must be checked against the
described problem.

Close #2989.

6fa4bcdc1d core: remove contract script check on deploy/update 
This check is good and was present here since #1729, but it was
accidently removed from the reference implementation (see the
discussion in https://github.com/neo-project/neo/issues/2848). The
removal of this check from the C# node leaded to the T5 testnet state
diff since 1670095 heigh which causes inability to process new blocks
since 2272533 height (see #3049). This check was added back to the
C# node in https://github.com/neo-project/neo/pull/2849, but it is
planned to be the part of the upcoming 3.6.0 C# node release.

We need to keep our testnet healthy, thus, strict contract script
check will be temporary removed from the node code and is planned
to be added back to be a part of the next 3.6.0-compatible release.

Close #3049.

7589733017 config: add a special Blockchain type to configure Blockchain 
And include some node-specific configurations there with backwards
compatibility. Note that in the future we'll remove Ledger's
fields from the ProtocolConfiguration and it'll be possible to access them in
Blockchain directly (not via .Ledger).

The other option tried was using two configuration types separately, but that
incurs more changes to the codebase, single structure that behaves almost like
the old one is better for backwards compatibility.

It doesn't store id->hash mappings for native contracts. We need blockchain's

other direct user of native.GetContractScriptHash is the VM CLI, but I doubt
anyone will use it for native contracts (they have ~zero VM code anyway).

It also brings ToStackItem to Block and Transaction, previously this was
avoided to separate block and transaction packages from VM. But turns out
`transaction` depends on `stackitem` already, so this makes little sense (but
can be shuffled in another way if needed).

Context.Container is still a hash.Hashable because we have a number of
occasions (header or MPT root verification) where there is no ToStackItem
implementation possible. Maybe they can go with `nil` Container, but I don't
want to have this risk for now.

1472c271e6 core: fix native NEO's getCandidateVote signature 
This commit fixes T5 statediff at block #0. Management's storage item
differs between neo-go and C# nodes, the reason in native NEO contract
state.

The parameter should have `pubKey` name, unlike the other `pubkey`
arguments in this contract.

9a06995460 bigint: don't allocate in ToPreallocatedBytes 
Turns out, it's almost always allocating because we're mostly dealing with
small integers while the buffer size is calculated in 8-byte chunks here, so
preallocated buffer is always insufficient.

Fix StorageItem reuse at the same time. We don't copy when getting values from
the storage, but we don when we're putting them, so buffer reuse could corrupt
old values.

b66f666267 core: ensure memcached Seek operation is properly cancelled 
PR #2495 is not enought, the problem is reproduced during dump restore
with the stacktrace attached down below.

The reason is that SeekAsync starts goroutine that performs Seek
operation over private MemCachedStore. The goroutine iterates over
MemCachedStore's map without holding the lock (it's OK, because it's
private), whereas the main thread continues invocation and
performs writes to the same map. To fix that ic.Exec() needs to
wait until all goroutines are properly exited.
