4b4bac675b core: don't print persisting errors twice
As they're already printed in the calling goroutine. And they're alse not
always useful when printed by Persist().

102c926ef3 core: don't print useless persist messages with nil errors
Errors should be printed only when there are errors.

100fee164b unitTest: reworked RPC unit test
earlier we had an issue with failing test in #353 and other one #305.
Reworked these test to have in-memory database. This led to multiple
changes: made some functions like Hash and Persist public(otherwise
it's not possible to control state of the blockchain); removed
unit_tests storage package which was used mainly for leveldb in unit
tests.
I see these tests not really good since they look like e2e tests and
as for me should be run in separate step against dockerized env or
in case we want to check rpc handler we might want to rework it in order
to have interface for proper unit tests.
As for me this patchset at least makes as safe with not removing totally
previous tests and at the same time CircleCI will be happy now.

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.

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.

b263c97bbb core: add some mechanism to drop bad blocks from cache
If we can't persist anything from our cache there is something wrong with
it. Try to remediate some possible problems.

7812fb28ea core: optimize blockchain init with existing DB
There is no need to generate genesis block (it's already in the DB) and we can
add all hashes at once without iterating over them.

a9b9c9226d *: add/fix godoc comments to satisfy golint
Fixes things like:
 * exported type/method/function X should have comment or be unexported
 * comment on exported type/method/function X should be of the form "X ..."

ec7e17ffa6 pkg: make use of the new crypto/hash package
Simplifies a lot of code and removes some duplication. Unfortunately I had to
move test_util random functions in same commit to avoid cycle
dependencies. One of these random functions was also used in core/transaction
testing, to simplify things I've just dropped it there and used a static
string (which is nice to have for a test anyway).

There is still sha256 left in wallet (but it needs to pass Hash structure into
the signing function).

* 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
4) Fixed bug in https://github.com/CityOfZion/neo-go/pull/174#discussion_r264108135
5) minor simplications of the code

* Fixed minor issues related to

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

1360e1de68 Added rpc unit tests (#107)
* Fixed small incosistencies related to comments and variable name

* For testing purposes we have to move the method newBlockchain from the cli/server/server.go to  pkg/core/blockchain.go. In addition we have to rename it to NewBlockchainLevelDB in order to be able to export it and avoid naming conflicts. In future we still need to think how to switch between different blockchain implementation easily but for the time being this is not possible.

* Added unit tests for the rpc server

* Added unit_testnet chain fixture

* fixed port number

* Added errors handling

* move unit_testnet chain from 'cli/chains' to 'pkg/rpc/chains'
