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.

fed95e0069 smartcontract: (un)marshal AnyType value as null 
Neo 3 can emit Null in its transfer notifications in `from` or `to` fields
when minting/burning tokens (unlike Neo 2 that emitted util.Uint256{} for this
case), then it gets converted to Parameter as AnyType and we have to JSONize
it somehow for proper RPC functioning.

3dbe549a61 smartcontract: store MapType Parameter as a slice of KV pairs 
Fixes #809.

Basically, there are three alternative approaches to fixing it:
 * allowing both []byte and string for ByteArrayType value
   minimal invasion into existing code, but ugly as hell and will probably
   backfire at some point
 * storing string values in ByteArrayType
   incurs quite a number of type conversions (and associated data copying),
   though note that these values are not changed usually, so dynamic
   properties of []byte are almost irrelevant here
 * storing only []byte values in ByteArrayType
   makes it impossible to use them as map keys which can be solved in several
   ways:
   - via an interface (Marshalable)
     which is good, but makes testing and comparing values in general harder,
     because of keys mismatch
   - using serialized Parameter as a key (in a string)
     which will need some additional marshaling/unmarshaling
   - converting MapType from map to a slice of key-value pairs
     not a bad idea as we don't use this map as a map really, the type
     itself is all about input/output for real VM types and this approach is
     also a bit closer to JSON representation of the Map
