0cbef58b3c consensus: enqueue newly created blocks 
Do not add them directly to chain, it will be done by the block queue
manager. Close https://github.com/nspcc-dev/neo-go/issues/2923. However,
this commit is not valid without
https://github.com/roman-khimov/dbft/pull/4.
It's the neo-go's duty to initialize consensus after subsequent block
addition; the dBFT itself must wait for the neo-go to complete the block
addition and notify the dBFT, so that it can initialize at 0-th view to
collect the next block.

d09158161e services/rpcsrv: Strengthen Server error channel's type 
According to docs, `Server` uses provided error channel only to write
encountered error to it. In this case, there is no need to accept rw
channel to create `Server` instance. Strengthening the type to
write-only will allow the caller to ensure control of reading errors
from the provided channel.

The change is backward compatible since any `chan` is `chan<-`.

584675ec23 state: optimize NEP17Transfer struct 
We have both from and to here, so technically we can either drop the neg/neg
trick from the processTokenTransfer() or drop one field from the structure
(the other side is a part of the key). Drop the field since this can make the
DB a bit more compact. Change Amount to be a pointer along the way since
that's the "native" thing for big.Int, we've used non-pointer field
specifically to avoid Neg/Neg problems, but it looks like this is not
necessary.

This structure is only used by the RPC server and I doubt anyone uses it via
the *Blockchain.

dfd4f6978f bigint: don't reallocate big.Int in ToBytes(), fix #2864 
In some cases n.Add() can reuse the []Word buffer and n.Sub() reallocate it
away. If that happens, we're out of luck with 0.99.0+ versions (since
3945e81857). I'm not sure why it does that, bit
width doesn't change in most of the cases and even if it does, we still have
enough of it in cap() to hold the old Abs() value (when we have a negative
value we in fact decreate its Abs() first and increase it back
afterwards). Still, that's what we have.

So when we have processTokenTransfer() doing Neg/Neg in-place its value is not
affected, but the original []Word bits that are reused by amount value are
(they're shared initially, Amount: *amount).

```

GetBlockByIndex payload can't be decoded, and the only possible cause
is zero (or <-1, but it's probably not the case) block count requested.

Error is improved as far.

d5a9af5860 is incompatible with the NeoFS
mainnet sidechain, so we add the old logic to the pre-Aspidochelone
behaviour. Changing flags at newMethodAndPrice() is a bit less convenient
unfortunately because this will affect interop validity checks, so let's have
this kludge here.
