63f4f34659 mempool: drop TxWithFee type 
All the fees are in transaction, this makes no sense.

a986e2a064 *: drop support for old on-chain assets 
You no longer can transfer them, so creating/renewing/storing doesn't make
much sense.

21efccd300 transaction: remove type field, set Version to 0 
Two changes being done here, because they require a lot of updates to
tests. Now we're back into version 0 and we only have one type of
transaction.

It also removes GetType and GetScript interops, both are obsolete in Neo 3.

3d18f09def core: fix CalculateClaimable for NEP5 NEO 
It's not stored as Fixed8, so calculations need to be adjusted for that.

39dfebccc4 core: no longer treat sysfee as claimable 
As it's not on Neo 3, it just gets burned and that's it. Only network fee is
being redistributed to CNs.

d9400800e3 transaction: drop Gas field from InvocationTX 
It essentialy is the new SystemFee, so use that. Had to increase GAS transfer
in test chain to 1000 to pay for deployment.

bf6525e54d core: fix GetUtilityTokenBalance 
The value stored in NEP5 tracker for GAS is Fixed8 already, so we need to
type-cast it, but not multiply by 10⁸ again.

44ae9086b6 core: improve and fix locking in storeBlock 
Getting batch, updating Prometheus metrics and pushing events doesn't require
any locking: batch is a local cache batch that no one outside cares about,
Prometheus metrics are not critical to be in perfect sync and events are
asynchronous anyway.

Native contracts also don't require any locks and they should be processed
before dumping storage changes.

4ebac5a069 core: fix bug in nep5 notifications handling 
Native contracts deployment creates `Transfer` notifications and adds
them into interop context. However, these notifications were not stored
for two reasons:
1. typo in `Transfer` (so these notifications were not recognised during
processing of the invocation tx in (*Blockchain).storeBlock(...) method)
2. these notifications have `from` adress setted to null, so conversion
to []byte fails. Same thing could happen with `to`.

Related C# issue: https://github.com/neo-project/neo/issues/1646

For now, made both `transfer` and `Transfer` valid.

30836ca69b core/native: untangle native contracts initialization 
The notion of NativeContractState shouldn't ever existed, native contract is a
contract and its state is saved as regular contract state which is critical
because we'll have MPT calculations over this state soon.

Initial minting should be done in Neo.Native.Deploy because it generates
notification that should have proper transaction context.

RegisterNative() shouldn't exist as a public method, native contracts are only
registered at block 0 and they can do it internally, no outside user should be
able to mess with it.

Move some structures from `native` package to `interop` also to avoid circular
references as interop.Context has to have a list of native contracts (exposing
them via Blockchainer is again too dangerous, it's too powerful tool).

82b230f19f core: rename *block.Base.GetHashableData to GetSignedPart() 
This allow to use `Block` as a Verifiable item.
When tx is provided, it is set as an interop's script container.
Otherwise, block is set.
