b4e4567c2b *: don't use CompareTo name for three-way comparison functions
"Compare" is almost a standard one now, although math/big uses Cmp for historic
reasons (keys.PublicKey does so too). This also fixes Fixed8 since int64 to int
conversion is lossy.

c7b623cc38 *: drop pkg/util/slice, use slices.Reverse
This also removes bigint.FromBytesUnsigned(), it's not used very often and
it's somewhat misleading in the bigint package (which is supposed to use a
very specific enconding).

8c31831626 util: reduce allocations in util.Uint256DecodeStringLE
It is used a lot in clients (including our benchmark).
`Uint160` is already optimized.

844491d365 *: use more efficient WriteBytes where appropriate
Before this patch on block import we could easily be spending more than 6
seconds out of 30 in Uint256 encoding for UnspentBalance, now it's completely
off the radar.

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.

* Added new config attributes: 'SecondsPerBlock','LowPriorityThreshold'

* Added new files:

* Added new method: CompareTo

* Fixed empty Slice case

* Added new methods: LessThan, GreaterThan, Equal, CompareTo

* Added new method: InputIntersection

* Added MaxTransactionSize, GroupOutputByAssetID

* Added ned method: ScriptHash

* Added new method: IsDoubleSpend

* Refactor blockchainer, Added Feer interface, Verify and GetMemPool method

* 1) Added MemPool
2) Added new methods to satisfy the blockchainer interface: IsLowPriority, Verify, GetMemPool

* Added new methods: RelayTxn, RelayDirectly

* Fixed tests

* Implemented RPC server method sendrawtransaction

* Refactor getrawtransaction, sendrawtransaction in separate methods

* Moved 'secondsPerBlock' to config file

* Implemented Kim suggestions:
1) Fixed data race issues
2) refactor Verify method
3) Get rid of unused InputIntersection  method due to refactoring Verify method

19201dcf52 Implemented rpc server method GetRawTransaction (#135)
* Added utility function GetVarSize

* 1) Added Size method: this implied that Fixed8 implements now the serializable interface. 2) Added few arithmetic operation (Add, Sub, div): this will be used to calculated networkfeeand feePerByte. Changed return value of the Value() method to int instead of int64. Modified fixed8_test accordingly.

* Implemented Size or MarshalJSON method.
- Structs accepting the Size method implement the serializable interface.
- Structs accepting the MarshalJSON method implements the customized json marshaller interface.

* Added fee calculation

* Implemented rcp server method GetRawTransaction

* Updated Tests

* Fixed:
1) NewFixed8 will accept as input int64
2) race condition affecting configDeafault, blockchainDefault

* Simplified Size calculation

* 1) Removed global variable blockchainDefault, configDefault
2) Extended Blockchainer interface to include the methods: References, FeePerByte, SystemFee, NetworkFee
3) Deleted fee_test.go, fee.go. Moved corresponding methods to blockchain_test.go and blockchain.go respectively
4) Amended tx_raw_output.go

* Simplified GetVarSize Method

* Replaced ValueAtAndType with ValueWithType

* Cosmetic changes + Added test case getrawtransaction_7

* Clean up Print statement

* Filled up keys

* Aligned verbose logic with the C#-neo implementation

* Implemented @Kim requests
Refactor server_test.go

* Small fixes

* Fixed verbose logic
Added more tests
Cosmetic changes

* Replaced assert.NoError with require.NoError

* Fixed tests by adding context.Background() as argument

* Fixed tests
