73b630db9b *: switch from fixed8 to int64
Follow C# implementation, we have to marshall JSON Fixed8 fields without
taking into account decimals.

5251607fb7 transaction: s/txid/hash/ for JSON to match C# implementation
It uses `hash` for transactions now, but `txid` for application logs.

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.

a7cce3f894 smartcontract: use new VerifiableDecodable for ParameterContext
And implement it for Transaction, the only user of ParameterContext for
now. Which make correct signing/verifying possible for cases when
serialization for general transmission and signing differ.

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.

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.

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.

388fed06e5 transaction: forbid serializing invalid transactions
Transaction that has no data is invalid and can't be serialized, so throw an
error if someone tries to.

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.

7e371588a7 core/tx: remove one layer of indirection for scripts and inouts
It reduces heap pressure a little for these elements as we don't have to
allocate/free them individually. And they're directly tied to transactions or
block, not being shared or anything like that, so it makes little sense for
them to be pointer-based. It only makes building transactions a little easier,
but that's obviously a minor usecase.

e299a44983 io: drop Size() method from Serializable and associated
It's no longer needed after the io.GetVarSize() improvement. It's duplicating
a lot of EncodeBinary() logic also.

0da9fe6946 io: move size calculator there
It's mostly used for Serializable and in other cases where one needs to
estimate binary-encoded size of the stucture. This also simplifies future
removal of the Size() from Serializable.

5bf00db2c9 io: move BinReader/BinWriter there, redo Serializable with it
The logic here is that we'll have all binary encoding/decoding done via our io
package, which simplifies error handling. This functionality doesn't belong to
util, so it's moved.

This also expands BufBinWriter with Reset() method to fit the needs of core
package.

 * comment on exported type/method/function X should be of the form "X ..."
