121c9664b4 core: restrict maximum gas allow for verification 
Disallow costly verification methods. We put this limit in policy
contract as it may be a subject to change in future.
In fact this value also overrides gas limit for header verification.

db027ad9c5 vm: zero GAS means no GAS, use fee data to properly limit execution 
We were accepting transactions with zero system fee, but we shouldn't do
that. Also, transaction's verification execution has to be limited by network
fee.

7eef895061 consensus: use GetNextBlockValidators where appropriate

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).

It is rather slow to get it from base every time we need to append to
it. This commit stores all NEP5Transfers in batches, so that
only a last batch needs to be unmarshaled during block processing.

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
user    96m17.200s
sys     13m37.084s

after:
real    159m16.551s
user    69m58.279s
sys     7m34.334s

So it's almost two-fold which is a great improvement.

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.

9b03f968b1 core: fixe FreeGasLimit constraint 
Lack of FreeGasLimit in privnet leads to gas limit exceeding in case of transactions with small amount of GAS to be used for invoke operation (< real cost of the transaction). Solution: Fixed constraint in case when FreeGasLimit == 0. So now we are able to perform transactions in privnet with FreeGasLimit = 0 for free.

b675903f52 mempool/core: redesign mempool dances on block acceptance 
We not only need to remove transactions stored in the block, but also
invalidate some potential double spends caused by these transactions. Usually
new block contains a substantial number of transactions from the pool, so it's
easier to make one pass over it only keeping valid items rather than remove
them one by one and make an additional pass to recheck inputs/witnesses.

bf84e1f2fb core: cache top block 
Turns out, our dApps use it a lot and we were going to the DB to get it which
is a useless waste of time. Technically we could also remove blockHeight here,
but not doing it at the moment as it's more involved.

It eliminates this time waste from the pprof graph, but doesn't change 1.4M ->
1.5M 100K mainnet block import test case in any noticeable way.

a7457d08a1 vm/core: add ID support for SYSCALL, redo interop registration 
This solves two problems:
 * adds support for shortened SYSCALL form that uses IDs (similar to #434, but
   for NEO 2.0, supporting both forms), which is important for compatibility
   with C# node and mainnet chain that uses it from some height
 * reworks interop plugging to use callbacks rather than appending to the map,
   these map mangling functions are clearly visible in the VM profiling
   statistics and we want spawning a VM to be fast, so it makes sense
   optimizing it. This change moves most of the work to the init() phase
   making VM setup cheaper.

Caveats:
 * InteropNameToID accepts `[]byte` because that's the thing we have in
   SYSCALL processing and that's the most often usecase for it, it leads to
   some conversions in other places but that's acceptable because those are
   either tests or init()
 * three getInterop functions are: `getDefaultVMInterop`, `getSystemInterop`
   and `getNeoInterop`

Our 100K (1.4M->1.5M) block import time improves by ~4% with this change.

eb1749d190 core: remove persisting from GetValidators() 
It's a getter function and even though it's quite fancy with its transactions
processing (for consensus operation) it shouldn't ever change the state of the
Blockchain. If we're to change anything here these changes may conflict with
the actual block processing later or may lead to broken state (if transactions
won't be approved for some reason).

This seriously improves the serialization/deserialization performance for
several reasons:
 * no time spent in `binary` reflection
 * no memory allocations being made on every read/write
 * uses fast ReadBytes everywhere it's appropriate

It also makes Fixed8 Serializable just for convenience.

d0f9a28196 vm/core: improve block import speed with PublicKey caching 
This change (closely related to the neo-project/neo#1321 proposal) speeds up
1.4M mainnet blocks import by 30%. Basically, we're eliminating key decoding
for block's multisignature that has the same keys most of the time.

Things I don't like about this patch:
 * yet another parameter for verifyHashAgainstScript()
 * vm keys are not copied in/out

But it's rather simple and solves the problem for this particular case, so I
think it's worth it.

7e371588a7 core/tx: remove one layer of indirection for scripts and inouts 
It reduces heap pressure a little for these elements as we don't have to
allocate/free them individually. And they're directly tied to transactions or
block, not being shared or anything like that, so it makes little sense for
them to be pointer-based. It only makes building transactions a little easier,
but that's obviously a minor usecase.
