a986e2a064 *: drop support for old on-chain assets 
You no longer can transfer them, so creating/renewing/storing doesn't make
much sense.

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.

d9400800e3 transaction: drop Gas field from InvocationTX 
It essentialy is the new SystemFee, so use that. Had to increase GAS transfer
in test chain to 1000 to pay for deployment.

JSON.

valid.

4912e4f425 *: drop Publish transaction type 
It shouldn't be used even in NEO 2 as it was substituted by contract
deployment interop functions.

5fa11987d2 core: add validUntilBlock field to transaction 
1. closes #841

2. Commented out test cases where binary transaction are used.
These test cases marked with `TODO NEO3.0: Update binary` and need to be
updated.

3. Updated other tests.

4. Added cache to calculateValidUntilBlock() RPC-client method.

65503aa9b4 core: add nonce field to transaction 
1. Closes #840: added Nonce field to transaction.Transaction and
removed Nonce field from transaction.MinerTx

2. Added following methods to different tx types:
  - NewMinerTx()
  - NewMinerTxWithNonce(...)
  - NewEnrollmentTx(...)
  - NewIssueTx()
  - NewPublishTx(...)
  - NewRegisterTx(...)
  - NewStateTx(...)
in order to avoid code duplication when new transaction is created.

3. Commented out test cases where binary transaction/block are used.
These test cases marked with `TODO NEO3.0: Update binary` and need to be
updated.

4. Updated other tests

5. Added constant Nonce to GoveringTockenTx, UtilityTokenTx and genesis
block to avoid data variability. Also marked with TODO.

9abda40171 testserdes: implement helpers for encode/decode routines 
Frequently one needs to check if struct serializes/deserializes
properly. This commit implements helpers for such cases including:
1. JSON
2. io.Serializable interface

634e9483d3 transaction: unmarshal Witness properly 
Both verification and invocation scripts need to
be unmarshaled from hex.
Also fix failing RPC tests: block contains non-pointer
`transaction.Witness` field and (*Witness).MarshalJSON method
is not called.

6add4f3e50 transaction: disallow negative outputs 
Otherwise it is possible to make outputs which will sum
to the expected value, but steal GAS from some other account.

72d72296c3 core: implement (*Transaction).GetSignedPart() 
Marshalling it and taking all but last byte violates incapsulation
and is just wrong in case transaction already contains any witnesses.

We don't need a pointer here and this change makes this field compatible with
Transaction.Inputs which is useful in many scenarios.

8b3080b972 io: rename Read/WriteBytes to Read/WriteB 
go vet is not happy about them:
  pkg/io/binaryReader.go:92:21: method ReadByte() byte should have signature ReadByte() (byte, error)
  pkg/io/binaryWriter.go:75:21: method WriteByte(u8 byte) should have signature WriteByte(byte) error

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.
