241d5f593e *: use methods of binary.AppendByteOrder where applicable
We often use binary.PutUint*, but almost all these cases have preallocated
buffer of the size that matches exactly the desired one and use a single or
a couple of calls to PutUint*. Thus, I don't think that replacing
binary.PutUint* by AppendUint* will make things better for all these usages.

d9644204ee native: make newEpochNextValidators always contain non-empty value
If it's the end of epoch, then it contains the updated validators list recalculated
during the last block's PostPersist. If it's middle of the epoch, then it contains
previously calculated value (value for the previous completed epoch) that is equal
to the current nextValidators cache value.

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.

ee4b8f883b core: check signers of on-chained conflict during new tx verification
During new transaction verification if there's an on-chain conflicting
transaction, we should check the signers of this conflicting transaction.
If the signers intersect with signers of the incoming transaction, then
the conflict is treated as valid and verification for new incoming
transaction should fail. Otherwise, the conflict is treated as the
malicious attack attempt and will not be taken into account;
verification for the new incoming transaction should continue.

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.

20b19d4599 interop/contract: fix state rollbacks for nested contexts
Our wrapping optimization relied on the caller context having a TRY block,
but each context (including internal calls!) has an exception handling stack
of its own, which means that for an invocation stack of

    entry
    A.someMethodFromEntry()   # this one has a TRY
    A.internalMethodViaCALL() # this one doesn't
    B.someMethod()

we get `HasTryBlock() == false` for `A.internalMethodViaCALL()` context, which
leads to missing wrapper and missing rollbacks if B is to THROW. What this
patch does instead is it checks for any context within contract boundaries.

Fixes #3045.
