f9f1fe03b2 core: refactor native call
1. `System.Contract.CallNative` expects version on stack.
2. Actual method is determined based on current
   instruction pointer.
3. Native hashes don't longer depend on NEF checksum.

1840c1c80d core: redefine opcode prices
Prices are defined in as a coefficients to `BaseExecFee` which
is defined by Policy contract (TBD later).
Native method prices are defined without need to multiply.

ad3547783d native: drop Neo.Native.Deploy, move contract init to management contract
The contract is almost a stub at the moment, though it does deploy other
contracts.

090bee8624 native: change OnPersist/PostPersist handling
Every contract now has these and they're always invoked. See
neo-project/neo#1913 and neo-project/neo#2119.

2290b91b83 core: fix verification call flag
Previous commit sets AllowCall flag as required for Neo.Native.Call, but
invocation script was loaded with ReadStates flag => native contracts
verification failed.

Other contracts can also make use of AllowCall call flag.

42ae226f9e native: use proper stack for result
When native method calls other contract result should be put
on the stack of current context. With oracles this problem wasn't
noticed because of void return type.

30526046e7 native: don't push void result in Call
This was done in https://github.com/neo-project/neo/pull/1693
for native calls. `OnPersist` script still uses `DROP` though
as value is pushed via `CheckReturn` logic for regular calls.

0e2784cd2c always wrap errors when creating new ones with fmt.Errorf()
It doesn't really change anything in most of the cases, but it's a useful
habit anyway.

Fix #350.

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).
