55b2cbb74d core: refactor and improve verification and pooling 
Now we have VerifyTx() and PoolTx() APIs that either verify transaction in
isolation or verify it against the mempool (either the primary one or the one
given) and then add it there. There is no possibility to check against the
mempool, but not add a transaction to it, but I doubt we really need it.

It allows to remove some duplication between old PoolTx and verifyTx where
they both tried to check transaction against mempool (verifying first and then
adding it). It also saves us utility token balance check because it's done by
the mempool anyway and we no longer need to do that explicitly in verifyTx.

It makes AddBlock() and verifyBlock() transaction's checks more correct,
because previously they could miss that even though sender S has enough
balance to pay for A, B or C, he can't pay for all of them.

Caveats:
 * consensus is running concurrently to other processes, so things could
   change while verifyBlock() is iterating over transactions, this will be
   mitigated in subsequent commits

Improves TPS value for single node by at least 11%.

Fixes #667, fixes #668.

c7032022f8 core: don't search through the whole DAO in isTxStillRelevant 
New transactions are added to the chain with blocks. If there is no
transaction X at height N in DAO, it could only be added with block N+1, so
it has to be present there. Therefore we can replace `dao.HasTransaction()`
check with a search through in-block transactions. HasTransaction() is nasty
in that it may add useless load the DB and this code is being run with a big
Blockchain lock held, so we don't want to be delayed here at all.

Improves single-node TPS by ~2%.

3a379e4f3e core: don't reverify mempooled transactions in AddBlock 
The end effect is almost as if `VerifyTransactions: false` was set in the
config, but without actually compromising the guarantees provided by it.

It almost doubles performance for single-mode benchmarks and makes block
processing smoother (more smaller blocks are being produced).

d0c29f52c9 core: verification script must return exactly one value 
C# node is quite picky as it expects there to be exactly one value returned,
but our testchain actually adds 4 signatures for multisig cases instead of 3
which makes it technically incompatible with C# node.

236438d799 core: do MPT compaction every once in a while 
We need to compact our in-memory MPT from time to time, otherwise it quickly
fills up all available memory. This raises two obvious quesions --- when to do
that and to what level do that.

As for 'when', I think it's quite easy to use our regular persistence interval
as an anchor (and it also frees up some memory), but we can't do that in the
persistence routine itself because of synchronization issues (adding some
synchronization primitives would add some cost that I'd also like to avoid),
so do it indirectly by comparing persisted and current height in `storeBlock`.

Choosing proper level is another problem, but if we're to roughly estimate one
full branch node to use 1K of memory (usually it's way less than that) then we
can easily store 1K of these nodes and that gives us a depth of 10 for our
trie.

6ca22027d5 mpt: implement (*Trie).Collapse() 
Because trie size is rather big, it can't be stored in memory.
Thus some form of caching should also be implemented. To avoid
marshaling/unmarshaling of items which are close to root and are used
very frequenly we can save them across the persists.
This commit implements pruning items at the specified depth,
replacing them by hash nodes.

ae9658a108 dao: migrate nep5 balances with the contract 
Fixes #1144. It's quite simple approach, we just update balance info right
upon contract migration. It will slow down migration transactions, but it
takes about 1-2 seconds to Seek through balances at mainnet's 3.8M, so the
approach should still work good enough. The other idea was to make lazy
updates (maintaining contract migration map), but it's more complicated to
implement (and implies that a balance get might also do a write).

There also is a concern about memory usage, it can give a spike of some tens
of megabytes, but that also is considered to be acceptable.

Fixes state mismatch for the key ffffffff0e00000000000000000000000000000001 in
the first blocks.

It also affects tests as now the first validator is different and it receives

7633439845 rpc/block: rework the way Block is JSONized 
Our block.Block was JSONized in a bit different fashion than result.Block in
its NextConsensus and Index fields. It's not good for notifications because
third-party clients would probably expect to see the same format. Also, using
completely different Block representation is probably making our client a bit
weaker as this representation is harder to use with other neo-go components.

So use the same approach we took for Transactions and wrap block.Block which is
to be serialized in proper way.

Fix `Script` JSONization along the way, 3.0 node wraps it within `witnesses`.

c7a040ff81 core: fix bug with native contracts methods initialisation 
`NewNEO()` and `NewGAS()` methods are trying to initialise
both `onPersist` and `incBalance` methods of NEO and GAS AFTER
nep5TokenNative is set to the VALUE of created nep5 token.
In this situation an attemmpt to call the corresponding native contracts
methods (e.g. transfer native GAS) leads to contract invocation failure,
as far as `nep5TokenNative.incBalance` method is nil.

Fixed this by initializing both `onPersist` and `incBalance` methods
before getting the value of nep5 contract.

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).

Most of the time it's persisted into the MemoryStore or MemCachedStore, when
that's the case there is no real need to go through the Batch mechanism as it
incurs multiple copies of the data.

Importing 1.5M mainnet blocks with verification turned off, before:
real    12m39,484s
user    20m48,300s
sys     2m25,022s

After:
real    11m15,053s
user    18m2,755s
sys     2m4,162s

So it's around 10% improvement which looks good enough.

23464401bc core/state: merge spent and unspent coins state, use it to store more things 
This change reduces pressure on DB by doing the following things:
 * not storing additional KV pair for SpentCoin
 * storing Output right in the UnspentCoin, thus eliminating the need to get a
   full transaction from DB

At the same time it makes UnspentCoin more fat and hot, but it should probably
worth it.

Also drop `GetUnspentCoinStateOrNew` as it shouldn't ever existed, UTXOs
can't come out of nowhere.

1.5M block import time (VerifyBlocks disabled) on AMD Ryzen 5 1600/16GB/HDD,
before:
real    302m9.895s

a9abd3d841 core: fix wrong endian used in interop functions 
C# uses ToArray() or UintXXX(bytes) here which interprets hashes as they
should be interpreted (BE, although they always convert to LE when converting
to String just for the fun of it). It leads to state difference for us at
block 2025204 where even though we have the same value for the key, the key
itself differs, ours:

dd2b538e2a0c1db1ae5061c15be14f916bd1e678e512ffcda6d9499d8e7fe97ee71fd6b8004583d9afe09cc4dadbd5deb63d01e061009b7cffdaa674beae0f930ebe6085af900093e5fe56b34a5c220ccdcf6efc336fc5000000000000000000000000000000000010

theirs:

dd2b538e2a0c1db1ae5061c15be14f916bd1e67861e0013db6ded5dbdac49ce0afd9834500b8d61fe77ee97f8e9d49d9a6cdff12e5009b7cffdaa674beae0f930ebe6085af900093e5fe56b34a5c220ccdcf6efc336fc5000000000000000000000000000000000010

In this key there is a tx hash encoded
(e512ffcda6d9499d8e7fe97ee71fd6b84583d9afe09cc4dadbd5deb63d01e061 in LE used
by all the tools like neoscan).

I love Neo.

eb11e5fb11 core: implement basic policying support, fix #370 
Implement mempool and consensus block creation policies, almost the same as
SimplePolicy plugin for C# node provides with two caveats:
 * HighPriorityTxType is not configured and hardcoded to ClaimType
 * BlockedAccounts are not supported

Other than that it allows us to run successfuly as testnet CN, previously our
proposals were rejected because we were proposing blocks with oversized
transactions (that are rejected by PoolTx() now).

Mainnet and testnet configuration files are updated accordingly, but privnet
is left as is with no limits.

Configuration is currently attached to the Blockchain and so is the code that
does policying, it may be moved somewhere in the future, but it works for
now.

c8a248596e core: introduce ValidatorsCount, make a proper count 
We were completely lacking ValidatorsCount that is supposed to track the
number of votes with particular count of consensus nodes which in theory can
change the number of active consensus nodes (if it ever to exceed the number
of standby validators), so we were not producing the right count and based on
that not giving the right set of validators.

Fixes #512.
