1eb9a4c6c6 core: allow to use verification contracts 
In NEO3 we can't just appcall hash, as verification script has no access
to state. Instead we use `verify` method of an arbitrary contract.

bcb7b9ba63 smartcontract: rename parameter ByteString to ByteArray 
Debugger expects it to be ByteArray. C# compiler also compiles it
as `ByteArray` (in both manifest and debug.json).

The previous commit 6a2161207a changed
this line as C# implementation serializes Blockchain.ApplicationExecuted.Stack
as array of stackitem.Item and deserializes it as array of
smartcontract.Parameter.

dba248236c smartcontract: add CreateDefaultMultiSigRedeemScript 
And use it where appropriate. Some of our code was just plain wrong (like the
one in GAS contract) and unification is always useful here.

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.

5ef08f60ae remove github.com/pkg/errors from dependencies 
It's not needed any more with Go 1.13 as we have wrapping/unwrapping in base
packages. All errors.Wrap calls are replaced with fmt.Errorf, some strings are
improved along the way.

685d44dbc1 *: support _initialize method in contracts 
Invoke `_initialize` method on every call if present.
In NEO3 there is no entrypoint and methods are invoked by offset,
thus `Main` function is no longer required.
We still have special `Main` method in tests to simplify them.

d2ddf7b7cb *: support invoking methods by offset 
Allow to invoke methods by offset:
1. Every invoked contract must have manifest.
2. Check arguments count on invocation.
3. Change AppCall to a regular syscall.
4. Add test suite for `System.Contract.Call`.

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.

9097a1a23d smartcontract: update (Parameter).MarshalJSON method 
MarshalJSON should be defined on structure (not pointer), as we use
structures to marshal parameters (e.g. in NotificationEvent and
Invoke of RPC result package) and never use pointers for that purpose.

Also added marshalling of nil array into `[]` instead of `null` to
follow C# implementation.

b483c38593 block/transaction: add network magic into the hash 
We make it explicit in the appropriate Block/Transaction structures, not via a
singleton as C# node does. I think this approach has a bit more potential and
allows better packages reuse for different purposes.
