N3 contracts require method and array of arguments to function correctly, but
CreateFunctionInvocationScript can produce scripts that won't work correctly
if one is to pass anything but a single array parameter to it. This doesn't
make much sense, so we can always expect there to be an array of parameters in
the third positional invokefunction argument (the same way C# node does).
In N3 no arguments passed should be treated as empty arguments array not as
missing array of arguments, because the array must be present even for
functions that accept no parameters.
In `(c *Client) AddNetworkFee` we define network fee for contract
witness verification via `invokecontractverify` RPC call, and that's the
initial purpose of this RPC method. But it was not implemented
correctly. It used `System.Contract.Call` instead of beheiving like
`initVerificationVM`.
During real contract witness verification the whole contract's script is
loaded into VM, and then we jump to the `verify` method. Thus, to define
exact contract verification price, we should act like this (and not just
perform `System.Contract.Call` of `verify` method).
Tests are added.
This bug is the reason of adding extra GAS (c.notary.extraVerifyFee) to
pre-calculated value in

It's just JSON, io.Serializable is only used for DB storage where the length
should be obtained from the stream. Fixes:

1. Remove GetScript, IsPayable, GetStorageContext.
2. Revert 82319538 related to GetStorageContext.
3. Rename Migrate to Update.
4. Move remaining to System.Contract.*.

That's how it was intended to behave originally. One thing questionable here
is contract price (policy thing, basically) being moved to smartcontract
package, but it's probably fine for NEO 2.0 (as it won't change) and we'll
make something better for NEO 3.0.
Merged two types:
- smartcontract.ParamType
- rpc.StackParamType
into single one:
- smartcontract.ParamType
as they duplicated the functionality.
NOTE: type smartcontract.MapType was added (as in C# implementation).
From now, list of supported smartcontract parameter types:
UnknownType
SignatureType
BoolType
IntegerType
Hash160Type
Hash256Type
ByteArrayType
PublicKeyType
StringType
ArrayType
MapType
InteropInterfaceType
VoidType
