5d514538cf rpc: add new header_of_added_block event subscription
New event is to notify the user about header's content by the moment
when block is stored (which happens after block's processing). This is
needed for proper Waiter work.

Closes #2751.

d7d850ac7d native: never set Neo's newEpoch* cache values to nil
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.

b31d39836a native: test immediate contract availability
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.

bbbc6805a8 native: fix NeoToken initialization process
Refactored native NeoToken cache scheme introduced in #3110 sometimes requires
validators list recalculation during native cache initialization process (when
initializing with the existing storage from the block that is preceded each N-th block).
To recalculate validators from candidates, native NeoToken needs an access to
cached native Policy blocked accounts. By the moment of native Neo initialization,
the cache of native Policy is not yet initialized, thus we need a direct DAO access
for Policy to handle blocked account check.

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.
