21efccd300 transaction: remove type field, set Version to 0
Two changes being done here, because they require a lot of updates to
tests. Now we're back into version 0 and we only have one type of
transaction.

It also removes GetType and GetScript interops, both are obsolete in Neo 3.

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.

03ecab5eec smartcontract: add JSON marshal/unmarshal for InteropType
We actually have to do that in order to answer getapplicationlog requests for
transactions that leave some interop items on the stack. It follows the same
logic our binary serializer/deserializes does leaving the type and stripping
the value (whatever that is).

5a62eb923e smartcontract: fix uint160 marshalling in smartcontract.Parameter
There's a bug after #785: smartcontract.Parameter of type hash160 should
be marshalled in LE (as default marshaller for uint160 does) instead of
BE, so fixed.

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

bbd802681e cli: make gas parameter to deployment add gas to the base price
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.

	SignatureType
	BoolType
	IntegerType

	ByteArrayType

54d888ba70 io: add type-specific read/write methods
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.

8d4dd2d2e1 vm: move opcodes into their own package
This allows easier reuse of opcodes and in some cases allows to eliminate
dependencies on the whole vm package, like in compiler that only needs opcodes
and doesn't care about VM for any other purpose.

And yes, they're opcodes because an instruction is a whole thing with
operands, that's what context.Next() returns.

supposedly it's also a nice choice for contract state storage).

b77e533d13 crypto/wallet: move public/private key into the new keys package
And drop associated _pkg.dev remnants (refs. #307).

Original `dev` branch had two separate packages for public and private keys,
but those are so intertwined (`TestHelper` subpackage is a proof) that it's
better unite them and all associated code (like WIF and NEP-2) in one
package. This patch also:
 * creates internal `keytestcases` package to share things with wallet (maybe
   it'll be changed in some future)
 * ports some tests from `dev`
 * ports Verify() method for public key from `dev`
 * expands TestPrivateKey() with public key check
