8f73ce08c8 rpc: move session maintenance related code out of the result.Invoke
It's server who should be responsible for iterator ID creation and
iterator registration.

b5d39a3ffd rpc: add configuration extension for MPT-backed iterator sessions
Add ability to switch between current blockchain storage and MPT-backed
storage for iterator traversing process. It may be useful because
iterator implementation traverses underlying backed storage (BoltDB,
LevelDB) inside DB's Seek which is blocking operation for BoltDB:
```
Opening a read transaction and a write transaction in the same goroutine
can cause the writer to deadlock because the database periodically needs
to re-mmap itself as it grows and it cannot do that while a read transaction
is open.

If a long running read transaction (for example, a snapshot transaction)
is needed, you might want to set DB.InitialMmapSize to a large enough
value to avoid potential blocking of write transaction.
```

So during bbolt re-mmaping, standard blockchain DB operations (i.e. persist)
can be blocked until iterator resourses release. The described behaviour
is tested and confirmed on four-nodes privnet with BoltDB and
`SessionExpirationTime` set to be 180 seconds. After new iterator session
is added to the server, the subsequent persist took ~5m21s, see the log
record `2022-06-17T18:58:21.563+0300`:

0da0bb21ee rpc: make getnextvalidators behavior compliant with C# node
Turns out, our getnextvalidators implementation already works the way
getcandidates is supposed to work, but original getnextvalidators works a bit
differently. It only returns validators, it doesn't return Active flag (all
of them are active) and it represents votes as a number. So for the maximum
compatibility:
 * drop non-validator keys from getnextvalidators server-side
 * drop Active flag client-side (sorry, it doesn't exist)
 * allow unmarshalling old answers along with the new one

This technically breaks `query candidates` CLI command, but it'll be fixed
when getcandidates are to be introduced.

9862b40f2c rpc: support InitialGasDistribution response from old Neo-Go nodes
https://github.com/nspcc-dev/neo-go/pull/2435 breaks compatibility
between newer RPC clients and older RPC servers with the following
error:
```
failed to get network magic: json: cannot unmarshal string into Go struct field Protocol.protocol.initialgasdistribution of type int64
```

This behaviour is expected, but we can't allow this radical change.
Thus, the following solution is implemented:
1. RPC server responds with proper non-stringified
   InitialGasDistribution value. The value represents an integral
   of fixed8 multiplied by the decimals.
2. RPC client is able to distinguish older and newer responses. For
   older one the stringified value without decimals part is
   expected. For newer responses the int64 value with decimal part
   is expected.

The cludge will be present in the code for a while until nodes of
version <=0.98.3 become completely absolete.
