It's not an ideal solution, but at least it solves the problem for
now. Caveats:
* consensus only needs one method, so it's mirrored to Blockchain
* rpcsrv uses core.* definition of the StateRoot (so technically it might as
well not have an internal Ledger), but it uses core already unfortunately
1. It's not good for pkg/core to import anything from pkg/neorpc.
2. The type is closely tied to the state package, even though it's not stored
in the DB
It makes a copy of the resulting set, so the lock can be released
earlier. This helps a lot with iterators that keep Seek() unfinished for a
long time,
Specifying a certain stateroot R as `invoke*historic` RPC-call
parameter, we're willing to perform historic call based on the storage
state of root R. Thus, next block should be of the height h(R)+1. This
allows to use historic functionality for the current blockchain height.
They test both module and service which is a bit wrong, but separating these
tests will lead to some duplication, so it's OK for now to have them in the
higher-order package (service imports module).
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.
This allows to reuse it across different packages.
testchain can't be used because of circular dependencies.
Init() is not changed except for filepath.Join() use instead of direct string
appends which is a better approach anyway. rootpath is required because
current directory will change from package to package.
